BMS Funtion :
1) SOC Calculating:Use Vmin EKF algorithm, dynamically estimate the battery pack SOC
2) Current detection: Via the Hall current sensor, real-time detection of the current charge and discharge circuit
3) Communication function: 3-Way Can interface outside, can communicate with BMU, vehicle controller, charger etc to collect interactive voltage, temperature,error code,control instructions and other information.
4) Alarm and Protection: When overcharge, over discharge happened, BCU can implement appropriate alarm and protection under error condition, and display on LCD screen.
5)System Expansion: BCU supports multiple active/passive node output, it can achieve ensuring the effective strength of electrical isolation, security controls via CAN communication and relay control and management levels, to meet customer diverse requirements.
6)Data storage:Support 8G data storage, can record power battery pack long-time running entire performance parameters and battery pack adjusting and errors.
7)System self-test
8) Remote management
