A Turnkey Solution for Designing Electric Commercial Vehicles

The future of commercial transportation is upon us – and it is electric. Now, Leclanché is leveraging its extensive experience in e-Transportation to allow bus and commercial vehicle developers to bring next generation e-commercial vehicles to market. An optional IoT tool allows remote data logging and real-time access to battery status, performance and diagnostic data – ideal for optimizing fleet operations. Whether you are planning to develop fully electric or hybrid solutions, let Leclanché help you hit the road smarter, quicker and risk-free. Meet INT-39 Energy.

What is it?

The INT-39 Energy HV pack is a “plug and play,” modular, all-in-one, high cycle life battery system for commercial vehicle manufacturers.

It is a fully engineered, self-contained battery system that is optimized to support the needs of e-Truck, municipal service, ground support equipment, construction vehicle and e-Bus designers.

Leclanché’s extensive experience in helping to design electric/hybrid vehicles for markets around the world is integral to the pack’s design.

The pack is available with an energy capacity of 39.4 kWh (at 657 V) and can be expanded to include as many as eight packs providing up to 315 kWh of energy capacity.

The INT-39 Energy HV pack is designed for installation within vehicles and is also suited to roof mounting applications given that the packs are fully self-supported and can be end-mounted.

Our in-house technology

European made cells and modules in Leclanché factories in Germany and Switzerland means no supply issue and almost immediate delivery. With a cycle life of 4000 cycle at 100% depth of discharge, our cells last significantly longer than other cells on the market. The results are lower costs of ownership. The high energy density enable the vehicle to cover a longer range before recharging.
