GB Auto to leverage Tembo 4×4 conversion kits for Australia mining sector electrification

VivoPower International and its 51% subsidiary, Tembo e-LV BV, have entered into a non-binding Heads of Agreement with GB Auto Group Pty Limited and GB Electric Vehicles Pty Ltd in Australia that will confirm and expand GB Auto’s position as the exclusive distributor within Australia for Tembo’s electric Toyota Land Cruiser, Hilux, and electric vehicle conversion kits.

The agreement proposed by the HoA contemplates a seven-year term. Following the successful deployment of several pilot vehicles into the Australian mining sector, GB Auto intends to commit to purchase at least 500 Tembo electric conversion kits in the first year, and at least 2,000 kits (including the first-year commitment) during the first four years. These orders would be worth around $250 million.

GB Auto plans to increase its Australian footprint, adding facilities to ensure the delivery on these volumes. Tembo will offer GB Auto a first right of refusal on distribution rights for any additional Tembo products.

VivoPower will own all vehicle data and grant GB Auto a non-exclusive, non-transferrable, no royalty licence to use it for sales and maintenance of Tembo products, VivoPower says.

“The proposed agreement would position VivoPower as GB Auto’s partner of choice for the sale, construction, installation, and maintenance of all sustainable energy solutions (SES) and services of Tembo’s products, including EV charging infrastructure, battery storage, renewable electricity generation, and micro-grids,” the company said.

VivoPower will also be GB Auto’s partner of choice for rental, leasing or other financing solutions for Tembo’s products or related SES solutions. VivoPower said the parties expected to finalise the agreement as promptly as practicable.

Executive Chairman and CEO of VivoPower, Kevin Chin, said: “We are very pleased to be entering this partnership with GB Auto Australia given their established track record and reputation with their customers, who comprise some of the world’s pre-eminent mining houses.”

CEO and Founder of GB Auto, Graeme Bensley, said: “We are very excited to partner with VivoPower in relation to their SES offering, incorporating Tembo electric vehicles. SES are ideally suited to the requirements of our mining sector customers. We are witnessing strong demand from these customers for EV and are confident of the strong long term growth outlook.”

Tembo 4×4 e-LV expands battery-electric retrofit range

Tembo 4×4 e-LV has added a new option to its line-up of battery-powered equipment for the underground mining industry, with an extra-large 10 personnel carrier joining the portfolio, according to one of its distributors.

The new conversion kit is specifically targeted for applications where a maximum number of people are required to be transported at once.

The more spacious supervision vehicle option, which comprises forward-facing six personnel carrier, will also be available as a battery-electric conversion kit.

Last year, Tembo signed an agreement with the GHH Group to include the electric off-road light duty vehicles within its product offering and its worldwide sales and service program. As part of the agreement, GHH offers the vehicles in Germany, Turkey, Greece, Russia, India, the USA, Mexico, Chile, New Zealand, South Africa, Botswana, Mozambique, Namibia, Tanzania, Zambia, Zimbabwe, the CIS states and Latin America.

The conversion kits are for both mechanical and electrical service vehicles, which are based on the enhanced, flatbed platform designed to take any special equipment like a crane or workshop machinery or service equipment for servicing mining machinery, GHH says.

The first Tembo Electric Cruiser came on the market in 2016. The company’s approach to turning the Toyota Land Cruiser and Hilux series into fully-fledged electric multi-purpose vehicles, especially for construction and mining industries, has been well received, with Boliden’s Tara mine, in Ireland, the first to trial one of its ‘green’ machine.

The Tembos correspond largely to the series standard of Toyota, but are equipped with an electric motor with 65 kW of power and 250 Nm of torque, a special 1:3 transmission and a powerful battery designed for at least 10 years or 8,000 charging cycles. They can achieve 80 km run time with a 28 kWh battery pack and 200 km with a 72 kWh battery pack.
In two-and-a-half hours the vehicles are charged from 20% to 80% with the single-phase charger. Using a three-phase charger, this charge time decreases to only one hour.

No external infrastructure is required for operation as a 15 kW charger is also on board with the single phase and a 22 kW with the three phase. Battery recuperation is in place and a charging cable wallbox can also be supplied with the vehicle, if required.

The vehicles reach a top speed of 80 km/h and can climb gradients of up to 45°, GHH says.

Tackling the big mine electrification questions

“There is consensus in the industry that once we start doing electrification, we will innovate much more in other areas of the mining space.”

If anyone in the mining sector thought electrification was not in their wheelhouse, Theo Yameogo’s words might make them think again.

Yameogo, Partner and National Mining & Metals Co-Leader at EY Canada, made such a statement during The Electric Mine Virtual Conference earlier this week. The event, organised by International Mining Events, brought leaders in the electrification space together to discuss the latest developments in the industry, of which there were many.

The stage was set for mine electrification reveals, and Henrik Ager, President of Sandvik Mining and Rock Technology (soon to be Sandvik Mining and Rock Solutions), did not disappoint, acknowledging that the company is currently working on development of what would be its largest underground truck: a battery-powered 65 t vehicle.

This was all part of the company’s aim to have a “full range electrified offering by 2022”, he said.

Azizi Tucker, Co-Founder and CTO of XING Mobility, was next up, providing an overview of the Taiwan-based company’s offering in his presentation: ‘Electrification from prototype to mass production’.

With a remit to provide commercial, industrial and specialty vehicle makers with modular, high power and safe battery and powertrain technologies, XING is making an entrance into the mining space at just the right time.

Tucker talked attendees through the elements that make the company’s IMMERSIO™ battery solutions ideal for the mining sector: “With the modular size and shape of our batteries, we can really suit any vehicles. We find this very popular with the original equipment manufacturers (OEMs) as they can utilise their existing chassis.”

The elimination of corrosion, ability to operate consistently in high-temperature environments, a variety of sealing techniques and the use of nickel-manganese-cobalt lithium-ion chemistry has allowed the company to provide the safe and enclosed battery solution miners are looking for.

He concluded by saying XING was in conversation with a variety of mining companies, mining OEMs and mine site operators about deploying solutions in the space.

Attendees were then treated to a demonstration of Tembo 4×4 e-LV’s Electric Cruiser via video during the session: ‘Green conversions: the Tembo 4×4 e-LV electric light utility vehicle platform’ (pictured below). They got up close and personal with the battery-electric utility vehicle as it travelled on- and off-road close to the company’s Netherlands HQ.

After a 15-minute demo showing off the Electric Cruiser’s attributes, Paul Smeters, Tembo 4×4 e-LV’s Marketing Manager, and Alexander Haccou, Tembo 4×4 e-LV’s Technical Director, joined the event to answer audience questions.

The inevitable query came up early during the live Q&A: have you tested this vehicle in an underground mine?

Haccou was prepared for this, explaining that Boliden’s Tara underground zinc-lead mine in Ireland was the first recipient of the company’s Electric Cruiser, and a unit had been operating there for a few years now observing many of the maintenance benefits battery-electric machines are becoming renowned for.

The Electric Cruiser has also been tested in Australia and Canada with the help of Tembo 4×4 e-LV partners in those regions, he added.

“We don’t use fast charging or battery swapping,” Haccou said in response to another question. “What we have seen in several mines is the daily amount of usage is less than the battery’s full capacity.”

After several questions related to an active thermal management system for batteries had come up in previous sessions, Nicolas Champagne’s entrance to the virtual event proved timely.

His presentation, ‘Battery thermal management system using a highly advanced dielectric fluid’, homed in on the use of a dielectric fluid with specific features to allow direct cooling of the battery electrochemical cells.

Champagne, Formulation Team Manager of the R&D department for TOTAL Lubricants, revealed results from use of the fluid in bench tests and simulations at the battery pack level, extrapolating what these results could mean for battery-powered vehicles in the mining sector.

He said the company is in discussions with at least one mining customer about deploying its fluid on a battery-powered vehicle.

After previous sessions had discussed the potential for fast charging and battery swapping, Champagne made clear that TOTAL Lubricants’ solution would prove beneficial in all battery-powered applications throughout the mining sector.

 

Following a lunch break, it was the turn of Epiroc’s Anders Hedqvist (Vice President of R&D, underground) and Franck Boudreault (Electrification Transformation Lead, underground) to deliver a scoop (pun intended).

The pair, during their presentation, ‘From one generation to the next – learnings from zero emission mining’, took it in turns to provide updates.

Boudreault revealed the company’s plan to create battery-electric conversion kits for not only Epiroc diesel-powered equipment out in the field but other OEMs’ machines, before Hedqvist disclosed the company’s in-development battery-electric 18 t LHD would be trialled at LKAB’s Sustainable Underground Mining (SUM) project in Sweden. Epiroc has already delivered a diesel-powered Scooptram ST18 to be trialled in autonomous mode at the SUM project.

It was Yameogo, a mining engineer with much experience operating in underground mines in Canada, that provided the event’s big picture talk in his presentation, ‘Will electrification spark the next wave of mining innovation?’

He talked up the need for industry collaboration between miners, OEMs and service providers in not only electrifying equipment and operations, but also other types of technology.

“That type of collaboration and co-creation framework will actually help mining companies also think about innovation and other items part of electrification and equipment, in general,” he said.

The focus narrowed slightly to open-pit electrification during Dr Bappa Banerjee’s talk, ‘An electric future for mine haulage’. Dr Banerjee, General Manager of Mining Equipment for Wabtec, emphasised from the off that there was no one-size fits all solution to going electric in this sector.

“It’s becoming clear to us…that perhaps it will be a combination of technologies that really help us get to a solution that is feasible,” he said.

This solution, he said, depended on the mine application and haulage scenario, underlining the need for technology flexibility.

In his presentation, Dr Banerjee pitted a diesel-powered haul truck with 2,500 horsepower (1,864 kW) as his baseline solution against a hybrid solution with a 2,500 hp diesel engine and 200 kWh battery as one alternative, and all-electric truck platforms equipped with trolley assist (with 800 kWh battery) and stationary charging (1,200 kWh battery).

The energy cost versus productivity outcome he showed proved his earlier point about different applications suiting different solutions, with varied results depending on if these trucks were deployed on downhill, uphill or flat hauls.

GE Transportation, since merged with Wabtec, has previously demonstrated a battery-diesel hybrid solution on a Komatsu 830E-1AC and Wabtec has plans to release trolley solutions for Komatsu 830E-5 and 930E-5 haul trucks in 2021, so this analysis includes hard industry data.

Dr Banerjee concluded on the decision-making aspect of going electric: “These are not just point in time decisions we have to make regarding the CAPEX and where we are in the lifecycle of the mine, but decisions across decades sometimes.

“Perhaps the best way to approach this would be to start with a technology that is more flexible up front or has more options.”

Brian Huff, Vice President of Technology for Artisan Vehicle Systems, a Sandvik Mining and Rock Technology business unit, used his presentation to reinforce that battery-powered solutions were the way forward in the underground environment.

‘Rethink the machine, not the mine’ was the title of his presentation and Huff stayed true to it from the off: “The basic message is that this is not as hard as you think it is. There is a real big change coming to the mining industry, but it may not be as difficult as you think to accomplish a conversion to battery-electric equipment.”

Similar to Hedqvist’s mention of the newfound freedom available to engineers when designing these next generation battery-electric machines, Huff explained that Artisan’s generation three BEV blueprint started with a battery-electric driveline and built from there.

“Major parts of the frame can be removed to facilitate swapping…[and you can have] double to triple the power density of the machine (compared with the diesel-powered equivalent) to improve performance,” he said.

He moved on to tackle the usual range anxiety question head on, displaying a video of a 13 km haul on a one-in-seven grade. Within this, he showed that the ability to swap batteries during the uphill haul meant there was no loss in haulage productivity when compared with the a similar payload diesel-powered machine.

The time losses related to battery swapping – around six minutes per swap with the Z50 – were more than offset by the increased haulage speed, according to Huff. “It is about 10% faster on the climb,” he said when comparing the BEV unit with a conventional diesel truck.

Productivity could be further boosted with the introduction of Artisan’s patented AutoConnect system. Fitted on the company and Sandvik’s newest 18 t payload LH518B LHD, this system allows the battery swap to be completed in well under five minutes, according to Huff. IM understands an AutoConnect retrofit option could allow the Z50 haul truck to match that swap time.

Add to this productivity benefit, decreases in operating cost and total cost of ownership, and it is hardly surprising Barrick recently signed off on a trial of four of these Z50s at its Turquoise Ridge joint venture gold mine in Nevada.

Safety, cost, maintenance, productivity and even battery life; you name it, The Electric Mine Virtual Conference discussed it.

The good news is a second dose of electrification talk is only four months away, with The Electric Mine 2021 conference taking place on March 15-16, 2021, in Stockholm, Sweden.

VivoPower to expand battery-electric vehicle reach with Tembo 4×4 e-LV investment

VivoPower International has signed a non-binding Letter of Intent (LoI) to acquire a 51% stake in specialist battery-electric and off-road vehicle company Tembo 4×4 e-LV BV.

The purchase consideration will be $4.7 million and VivoPower will have the option to acquire the remaining 49% of Tembo in the future, it said.

Founded in the Netherlands, Tembo has since grown its global sales and distribution channels across four continents, with customers in Australia, Africa, Europe, and North America. In April, it signed a distribution agreement with ACCÈS for its Electric Cruiser (covering the province of Quebec), while in June, it added CPS Africa as a distributor in parts of Africa.

For its fiscal year ended December 31, 2019, Tembo generated $2.3 million in revenue and an EBITDA loss of $0.2 million (unaudited), derived from battery-electric and off-road vehicle solutions, VivoPower said.

Executive Chairman and CEO of VivoPower, Kevin Chin, said: “We are very pleased to have the opportunity to invest in Tembo and to partner with Frank Daams and his team. We believe that this will deliver a win-win outcome for both parties, given the growing interest in electric vehicles from VivoPower’s customer base and the proven capabilities, technology and solutions that Tembo has already been delivering.

“Importantly, this investment would expand VivoPower’s market for electric light vehicles (ELVs) and sustainable energy solutions significantly beyond the Australian mining and infrastructure sectors. We believe that consummation of this transaction has the potential to transform our addressable market into a global one. Based on an analysis of publicly available industry data, the company estimates that the potential global addressable market for ELVs could be at least $36 billion within the markets in which Tembo is currently active (which presently do not include the United States, Asia or South America).”

Founder and CEO of Tembo, Frank Daams, said: “We are delighted by the prospect of welcoming VivoPower as a shareholder. We believe that VivoPower will bring significant value add, especially given their diverse customer base for which we can deliver a battery-electric vehicle solution. The investment has the potential to enable us to scale up production capacity, expand our global salesforce and invest further in R&D and product development.”

VivoPower, an international battery technology, electric vehicle, solar and critical power services company, is conducting due diligence and is in the process of negotiating definitive documents with Tembo in line with the LoI. The company anticipates entering into a definitive agreement with Tembo and plans to disclose the terms of such definitive agreement when and if executed. The company is working to close the transaction as promptly as practicable, subject to finalising confirmatory tax, legal and accounting due diligence.

CPS Africa aligns with Tembo 4×4 e-LV to offer Electric Cruiser

CPS Africa is entering the underground mine electrification arena with the help of Tembo 4×4 e-LV and its Electric Cruiser.

The Belgian branch of CFAO Automotive, CPS Africa says it has signed a deal with Tembo that will see it offer the battery-electric support vehicle to parts of the Africa market (those outside of South Africa, Botswana, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe).

CPS said: “The challenges for the modern mining industry are clear: reducing health and safety risks in numerous mining sites, while gravely decreasing gaseous emissions – diesel particles in particular.

“The use of diesel-powered vehicles in the mining industry is rapidly decreasing, and now there is a safer and cleaner solution available: the Electric Cruiser developed by Tembo 4×4 e-LV based in the Netherlands.”

The Electric Cruiser is based on the Toyota Land Cruiser 70 series model, and is available as an all-wheel drive vehicle in several versions. The vehicle is equipped with a 110 kW electric motor with 250 Nm torque.

The temperature-controlled, modular and exchangeable battery provides a range of 80-100 km in proven underground use, according to Tembo.

“The battery is designed for a long service life of at least 8,000 charging cycles (80% depth of discharge) and charges from 20% to 80% in 1.5 hours,” the company said.

External infrastructure is not required, with a 22 kW charger on board the vehicle.

Tembo claims the Electric Cruiser reaches a maximum speed of 80 km/h and can negotiate inclines of up to 45°.

Some of the key findings early adopters of the Electric Cruiser experienced in Australia, Canada, Germany, Ireland and Sweden include low direct operating costs and substantially lower underground mining ventilation costs, CPS Africa said.

“As one of the market leaders in automotive distribution on the African continent, CPS Africa saw great potential for the Electric Cruiser and, from now on, these innovative electric off-road light duty vehicles are an essential part of their product portfolio,” the company said.

Strategically located in Antwerp, Belgium, CPS Africa says it can guarantee fast and reliable deliveries, being in proximity of the second busiest container port in Europe.
