Abstract

The invention discloses an optimal control method for detecting a battery state based on a V2G function. The method comprises the following steps: controlling an optical storage charging detection system to charge a vehicle battery to a first cut-off condition, discharge the vehicle battery to a second cut-off condition and recharge the vehicle battery to the first cut-off condition in sequence; detecting an electricity utilization peak-valley period, if the electricity utilization peak-valley period is in the peak electricity period, checking the state of a vehicle battery, and if the vehicle battery is in the charging stage, preferentially controlling other vehicle batteries in the discharging stage to charge the vehicle battery; if the vehicle battery is in the discharging stage, the vehicle battery is preferentially controlled to supply power to other vehicles with charging requirements; otherwise, the state of the vehicle battery is checked, and if the vehicle battery is in the charging stage, other vehicle batteries in the discharging stage are preferentially controlled to charge the vehicle battery; and if the vehicle battery is in the discharging state, the vehicle battery is preferentially controlled to charge the energy storage module of the optical storage charging detection system.
