Battery Control System Function

It receives battery status information from various sensors of electric vehicle to prevent a failure due to a battery abnormality.
It receives the charging voltage of the battery for each cell and detects the charging state and the internal state of the battery.
Where a difference in charging voltage occurs for each cell inside a battery, the voltage deviation between the cells is reduced through cell balancing.
When a battery is found to be abnormal, if there is a risk due to an increase in the internal load of the battery, the main relay circuit is blocked to prevent safety accidents.
When charging and discharging a battery, the temperature of each cell inside the battery is detected and the battery state is continuously checked through CAN communication.
The charge and discharge voltages according to the cell voltage are controlled.
When the internal temperature of the battery rises, the internal temperature of the battery is controlled to an optimal level through cooling water and air conditioning refrigerant.
