The invention relates to the related technical field of vehicles. The invention discloses a vehicle battery charging and discharging control method and device, electronic equipment and a storage medium. The method comprises the steps that a charging pile electrically connected with a vehicle charging and discharging interface is controlled to charge a vehicle power battery through a direct connection charging circuit of a vehicle charging and discharging circuit, and the vehicle charging and discharging circuit comprises a boosting charging circuit based on a motor system and the direct connection charging circuit; the vehicle charging and discharging interface is in on-off connection with a vehicle power battery through a boost charging circuit and a direct connection charging circuit which are connected in parallel; the battery voltage of the vehicle power battery is detected, and when the battery voltage is larger than or equal to a preset voltage threshold value, the charging pile is controlled to charge the vehicle power battery through the boost charging circuit. The method adapts to the voltage change of the battery in the charging process, so that the battery can be continuously charged when the voltage exceeds the maximum voltage of the charging pile, and the battery can be fully charged.
