Some time ago, Volkswagen announced a recall of the electric version of its Golf sedan (e-Golf) sold in the United States because its battery management system may regard internal current surges as critical current conditions, causing the vehicle's electric motor to suddenly stall. First, let’s take a look at Volkswagen’s battery structure
The high probability here is that the battery management system detects a high current pulse and then performs protection. The level definition of this fault is relatively high.
When we are considering this matter, we can take a look at the German architecture. In fact, it is a relatively high-level battery management system (BMS main module ASILC).
I think many BMS algorithms can be placed directly in VCU. Let’s do the following analysis:
1) Measurement function:
1) Basic information measurement: monitoring of battery voltage and current signals, and detection of battery pack temperature. The most basic function of the battery management system is to measure the voltage, current and temperature of the battery cells. This is the top-level calculation and control logic of all battery management systems. Base.
2) Insulation resistance testing: Insulation testing of the entire battery system and high-voltage system is required in the battery management system.
3) High-voltage interlock detection (HVIL): used to confirm the integrity of the entire high-voltage system. When the integrity of the high-voltage system loop is damaged, safety measures are initiated.
2) Estimation function
1) SOC and SOH estimation: the core and the most difficult part
2) Balance: When there is an imbalance of SOC × capacity between cells, adjust it through the balancing circuit.
3) Battery power limitation: There are certain limits on the input and output power of the battery under different SOC&temperatures.
