Real EV dataset

This dataset contains data obtained from batteries of five commercial electric buses operating in Chengdu, China. Each vehicle was monitored over a period of approximately seven months. Battery packs installed in these EVs consist of more than 180 serially connected single lithium-ion cells. Data of battery voltage, current, SOC, and surface temperature were collected through control area network (CAN) communication every 10 seconds. The battery packs underwent dynamic multi-step fast charging profiles and dynamic discharging profiles. In all cases, the charge-discharge processes are incomplete.
