Peaking Power Sources and Energy Storages

“Energy storages” are defined in this book as devices that store energy, deliver energy outside (discharge), and accept energy from outside (charge). There are several types of energy storages that have been proposed for EV and HEV applications. These energy storages, so far, mainly include chemical batteries, ultracapacitors or supercapacitors, and ultra-high-speed flywheels. The fuel cell, which essentially is a type of energy converter, will …
