Storage technologies for electric vehicles

So, ESS is required to become a hybrid energy storage system (HESS) and it helps to optimize the balanced energy storage system after combining the complementary characteristics of two or more ESS. Hence, HESS has been developed and helps to combine the output power of two or more energy storage systems (Demir-Cakan et al., 2013).
