Part of our high-energy ZEN range, the ZEN 42 is a battery pack that can be recharged at night, enabling heavy vehicles to travel more than 300 km without recharging. Incredible performance to limit your impact on climate change.
On the roof, at the rear, on the sides or in the chassis, ZEN 42 batteries fit into any space in the vehicle. The NMC lithium-ion cells installed in ZEN 42 high-energy batteries deliver high performance for intensive daily use on 100% electric buses and trucks.
Thanks to their narrow width, these batteries can also be installed on the sides of the vehicle chassis.
Heavy-duty electric vehicle powertrains generally operate at up to 730 V, so the voltage range of ZEN 42 batteries is 510 V to 736 V for optimum adjustment.
Autonomy boosted by ultra-high energy density cells
147 Wh/kg and 156 Wh/L. Composed of safe, industry-proven NMC lithium-ion cells, ZEN 42 batteries offer excellent energy density, enabling electric vehicles to operate autonomously for a full day, while optimizing available volumes.
A format optimized for ZEN 42
Roof-mounted, rear-mounted, side-mounted or chassis-mounted, ZEN 42 batteries fit into any vehicle space. The NMC lithium-ion cells installed in ZEN 42 high-energy batteries deliver high performance for intensive daily use on 100% electric buses and trucks.

Reliability and durability
To design the ZEN 42 battery, our experts in mechanical engineering, thermal engineering and electronics worked together to develop a reliable, high-quality product at the cutting edge of innovation.
This high-energy battery has an excellent service life, thanks to the integration of premium pocket lithium-ion cells.
The safety and durability of these cells have been proven in numerous industrial sectors and by the extensive use of ZEN 42 batteries by their operators.
This results in a very competitive total cost of ownership (TCO).
The estimated lifetime of a bus is 8 years.
