Effect of Voltage on Current Flow. The voltage in a battery circuit diagram influences the flow of electric current. According to Ohm''s law, the current (I) in a circuit is directly proportional to the voltage (V) and inversely proportional to the resistance (R) of the circuit, represented by the equation: I = V/R. Therefore, as the voltage

This circuit measures the amount of current flowing in and out of the battery pack, enabling accurate estimation of the state of charge and detecting any abnormal current conditions, such as a short circuit. By monitoring current levels, the BMS can maintain the battery within safe operating parameters and prevent potential hazards.
The BMS monitors the battery pack to protect both the battery and the rest of the system. A substandard BMS not only reduces the system''s safety, but it also provides inaccurate battery SOC management. These inaccuracies have a very significant effect on the product''s final quality, as they can result in potentially dangerous faults, or faults that negatively impact user

Therefore, in discharging mode, current flows in the opposite direction from charging mode, out of the HV+ terminal. Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode.
