Explore where we enhance vehicle performance.

Continental designed-in our ultracapacitor technology for the voltage stabilization system supporting start-stop in Lamborghini and PSA Peugeot Citroën models, and that’s only the beginning. Automotive leaders are pushing the boundaries of what the vehicle can attain experientially and mechanically. Complex, high-power applications become possible with our solutions.

Start-stop
Maxwell’s ultracapacitors relieve vehicle batteries from high current, repetitive cycling for seamless engine restarts.

 

Regenerative energy recovery
In regenerative systems, energy is captured, stored and re-used at a later time. Maxwell’s ultracapacitors have superb efficiency rates for this specialized application.

 

Power assist hybrid electric vehicles
In mild and full hybrid vehicles, ultracapacitors can reduce battery drain and lengthen battery life.

 

Short-term backup power
The car of the future will be dependent on sensor technology, which requires backup power in the event of battery failure. Ultracapacitors are an ideal solution for reliable system redundancy.

 

Peak power assist for high power functions
Power demands are increasing in the automobile, and batteries cannot meet all the requirements for these demands. Maxwell fills the performance gap for peak power applications such as boardnet stabilization and electric power steering.
