A key point in the development of storage batteries for electric vehicles (EVs) is the possibility for fast recharging. It is widely recognized that the lead/acid system represents an excellent candidate for EVs because of the low cost, durability, and expectance of improvements in the near future. The viability of the lead/acid battery for EV applications would be greatly enhanced if fast recharging could be applied to the system without shortening its life. The present paper reports the results obtained by simulating the charging behaviour with a mathematical model that is capable of predicting the behaviour of nonconventional lead/acid cells both on discharge and recharge. The effects of important parameters such as plate dimensions, acid distribution, and porosity of the active mass are taken into account. The data obtained with the simulation are compared with results got from fast-recharge testing of commercial batteries
