The invention discloses a transient control method for charging and discharging conversion of an automobile battery, computer equipment and an automobile, and the method comprises the steps: inputting the charging and discharging data of the last moment, and enabling the charging and discharging data to comprise target charging and discharging power, an instantaneous charging and discharging state and zero power retention time; obtaining steady-state target charging and discharging power; determining current instantaneous real-time theoretical output target charging and discharging power; determining a current instantaneous charging and discharging conversion mark; setting a charging and discharging conversion time threshold value, and determining current instantaneous charging and discharging data; the power battery executes target charging and discharging power in the current instantaneous charging and discharging data; and inputting the current instantaneous charging and discharging data into the next instantaneous charging and discharging data, and repeating the steps. When charging and charging of the power battery are mutually converted, a set duration is kept at a zero power point; direct reversion of chemical reaction in the power battery is avoided, and the service life and reliability of the power battery are improved; and when the current instantaneous target charging and discharging power is not subjected to charging and discharging conversion, the current instantaneous target charging and discharging power stably follows the steady-state target charging and discharging power.
