Elucidation of the results and uses of the lithium-ion battery management system

1. Battery parameter detection. Including total voltage, total current, single lithium-ion battery voltage detection (preventing overcharge, overdischarge or even reverse polarity), temperature detection (preferably each string of batteries, critical cable discussion, etc. have a temperature sensor), smoke detection ( Monitoring electrolyte leakage, etc.), insulation detection (monitoring leakage), collision detection, etc. 2. The state of lithium-ion battery is expected. Including state of charge (SOC) or depth of discharge (DOD), health state (SOH), performance state (SOF), energy state, hindrance and safety state (SOS), etc. 3. Online hinder diagnosis. Including obstruction of detection, obstruction of example determination, obstruction of positioning, obstruction of information output, etc. Obstruction detection refers to the collection of sensor signals, recovery of diagnostic algorithms to diagnose obstruction cases, and early warning. 4. Battery safety control and alarm. Including thermal system control, high-voltage power safety control. After the BMS diagnoses the obstacle, it informs the vehicle controller through the network and requires the vehicle controller to carry out effective processing to prevent high temperature, low temperature, overcharge, overdischarge, overcurrent, leakage, etc., to the lithium-ion battery and personal damage. 5. Charging control. There is a charging management module in the BMS, which can control the charger to safely charge the lithium-ion battery according to the characteristics of the battery, the temperature fluctuations and the power level of the charger. 6. Battery balance. The existence of ambiguity makes the capacity of the lithium-ion battery pack smaller than the capacity of the smallest monomer in the pack. Battery balancing is based on the information of single cells, recycling active or passive, dissipative or non-dissipative balancing methods, as far as possible to make the capacity of the battery pack close to the capacity of the smallest cell. 7. Heat up. According to the temperature distribution information and charging and discharging requirements in the lithium-ion battery pack, the intensity of active heating/dissipation is determined, so that the battery can work at the most suitable temperature as much as possible, and the battery function can be fully utilized.
