Valve-regulated Lead Acid Battery (VRLA Battery) suitable for use in EV (Electric Vehicle) with high output power and high regenerative charge characteristics has been developed by enhancing performance of lead acid battery that is superior in reliability and cost performance. In order to solve the problem of low energy density of LA batteries compared with other batteries such as Ni/MH and Li-ion rechargeable batteries, fast charge has been studied as an important method to increase EV's range per charge. However, fast charge has a problem that charging is stopped insufficiently due to a sudden increase in voltage and battery temperature during constant current charge at high rate. This paper focuses on pulse charge as a solution to extend the total driving distance of EV while using LA battery. For this purpose, drafts were evaluated as the influence of high-rate pulse charge on fast charge performance and active materials, and the influence of partial charge cycle including equalization charge on cycle life performance.
