【Abstract】 Nickel-Metal Hydride(NiMH) batteries are the promising power batteries for EV and HEV due to their high specific energy,high power,long life and wide operating temperature range.The state of charge (SoC) of batteries is much necessary both in electric and in hybrid vehicles as it is a measure of the amount of electrical energy stored in it.According to the current situation at home and abroad, the development of modeling and SoC estimator of NiMH battery for EV is presented, and suitable situation for every method is introduced.更多还原
