Design and Implementation of BMS Based on STC12C5A60S2

In connection with adverse effects of the single battery’s performance inconsistency of Lithium-ion batteries for electric vehicle, we’ve designed the battery management system and its balanced module. The systems based on MCU(Micro Controller Unit) STC12C5A60S2 accurately real-time capture and analyzes processing on the parameters of the battery pack, and then carry out function of balanced charge and discharge, management and protection by control circuit for battery pack. The results show that the system not only could make the charge and discharge of battery balance but also could effectively compensate the battery’s inconsistency, so that each battery has played the best performance.
