216 216  When battery modules are connected in parallel, the most charged modules transfer charge to the least charged modules. The process of charge transfer is accompanied by the flow of balancing currents. The BMS Main X device detects modules with high balancing currents and generates “Current unbalance (CH)” (charge circuit) and “Current unbalance (DCH)” (discharge circuit) errors for them.
