Abstract

Battery management system (BMS) is an inevitable process when it comes to electrical vehicles the battery health (SOH), state of charge (SOC), C-rate, E-rate, temperature all the said parameters relatively depend directly on remaining useful life of the battery. The above said are the various parameter involved in the BMS. The energy storage system becomes more important technology need to be taken almost care for the longer life of the battery. The different types of battery lead to the different range of outputs, so choosing the battery type will need to be taken care for the need of electrical vehicle types it is not only for electrical vehicles. It is also important for hybrid electrical vehicles, there are various techniques involved in the estimation SOH and SOC, which becomes the basic parameter for battery management system. In the past decades, electrical vehicles became a part of human need, which in turn greatly reduces the gas pollutants; however, the disposal of battery wastage is also to be a considered.
