Hybrid Energy Storage Systems (HESS) consist of two or more energy storage devices that offer different attributes and together can deliver a more capable overall system.
Hybrid Battery Pack
In the automotive world, a hybrid battery pack is one that uses more than one type of battery cell or supercapacitor. The aim being to provide a broader set of capabilities, such as:
- Improved balance between energy and power
- Hot and cold performance
- More accurate state estimation
Note: we have to be careful as a “Hybrid Battery Pack” can also be a battery pack from a Hybrid Electric Vehicle.
