N2 - Batteries are a critical component that largely governs the performance and cost of an electric vehicle. There are a variety of types of batteries competing for use, each with cons and pros. Among these options, Li-4 Ti-5 O-12 batteries excel with superior performance in terms of safety, stability, service life. In order to make better use of its merits for electric vehicle applications, understanding its charging/discharging characteristics becomes of necessary importance. To this end, this paper experimentally investigates internal resistance evolution, cathode thermal properties, charging/discharging characteristics against different rates, as well as the influence of temperature on charging/discharging process. Then, charging/discharging ca d analyzed in detail. The results show that mass energy density of Li4 Ti-5 O-12 battery is only 69.45Wh/kg, the volume energy density is only 82.94Wh/L, DC resistance is just pacity and energy against -30°C and 45°C are selected an only 0.5∼1.2m, Charging/discharging capacity and energy against high temperature increases by 50mAh and 240mWh, whereas, the same process against Low temperature only lasts 20s, leading to sharply decline of capacity and energy.
