Batteries for hybrids
In hybrid systems, the electric motor powered by batteries assists the combustion engine during start-up and acceleration. This synergy allows manufacturers to reduce the size and power requirements of the combustion engine, therefore lowering fuel consumption and improving overall efficiency.
Start-up & acceleration generate a lot of heat and place heavy demands on batteries, which must therefore possess advanced characteristics. With unmatched temperature control, our batteries are ideally suited for hybrid applications.
WATTALPS battery solutions deliver full performance at extreme temperatures, unmatched power density, energy savings and certified safety.
When selecting a battery for hybrid powertrains, you may consider the following key challenges.
Key challenges for batteries used in hybrid applications
Thanks to our battery solutions based on immersion cooling technology, we have helped our customers address these challenges successfully.
High power density
Hybrid batteries must provide high power output for acceleration and regenerative braking.
Weight vs. efficiency trade-off
Hybrids include two sources of energy, increasing space and weight constraints. A battery must store enough energy to power the electric motor but also needs to be lightweight to maintain fuel efficiency.
Frequent charge-discharge cycles
Hybrid systems constantly switch between battery power and combustion engines, requiring batteries to handle frequent charging and discharging efficiently.
Thermal management
Frequent charge-discharge cycles generate heat, which can degrade battery performance over time. Effective cooling systems are essential to prevent overheating, maintain performance and maximize life.
Regenerative braking
Hybrid vehicles capture energy during braking and store it in the battery, with high levels of current inrush, putting strong stress on the cells.
Cell balancing
WATTALPS has implemented specific balancing technology for hybrid powertrains, enabling to trigger balancing even if the battery remains at partial charge (no need for full charge to trigger balancing).

Example of a WATTALPS battery system designed for hybrid powertrain
39kWh – 280kW
In this use case, the challenge issued by our customer for his hybrid truck was not only to meet the battery performance requirements in terms of kW and kWh, but also to downsize the battery in order to reduce fuel consumption and increase payload capacity.
Thanks to our patented immersion cooling technology and battery design, not only did we meet the performance specifications but we also managed to reduce the size & volume by 3.
