The dual battery control method of the vehicle according to the present invention will now be described in detail.

The dual battery control method for a vehicle according to the present invention is a method for controlling a dual battery of a vehicle according to the present invention, A maximum charge control step S151 of charging the first battery group 12 and the second battery group 13 at maximum to stop the operation of the generator 11 and stopping the operation of the generator 11 from the second battery group 13, (S152) for directly supplying power from the generator (11) to the electric load (14), or a no-charge control step (S153) for supplying power directly to the electric load (14) And a first battery charge control step (S154) in which only the first battery group 12 is charged.

The dual battery control method for a vehicle according to the present invention uses the dual battery control device of the vehicle described above and also the dual battery control method for a vehicle according to the present invention is characterized in that the first battery group 12 and the second battery group 13 Are each composed of a plurality of batteries.

The driving state determination step (S110) determines whether the vehicle is currently decelerating. If the vehicle is decelerating, the maximum regenerative energy can be used from the vehicle to determine whether the vehicle is decelerating. Since the specific method of determining whether the vehicle is decelerating is a normal technique, a detailed description thereof will be omitted.

If it is determined in step S110 that the vehicle is decelerating, the control unit 15 controls the switch 16 installed between the generator 11 and the second battery group 13 (step S131) Is turned ON. When the switch 16 is turned on, the generator 11 and the second battery group 13 are electrically connected.

The maximum charge control step S151 is performed after the first switch-on step S131. The maximum charge control step (S151) is a step of obtaining the maximum regenerative energy from the vehicle because the vehicle is in deceleration state. Therefore, the maximum voltage is output from the generator 11 to charge the first battery group 12 and the second battery group 13 to the maximum.

The second battery charging state determining step (S120) is executed when it is determined that the vehicle is not decelerating in the traveling state determining step (S110). In the second battery charging state determining step S120, the charging state of the second battery group 13 is compared with the non-generating control entering second battery charging amount a, It is determined whether the charge state is higher than the non-power generation control entry second battery charge amount (a).

The second switch on step S132 is performed when the amount of charge of the second battery group 13 in the second battery charging state determining step S120 is greater than the charging amount a of the no power generation control entering second battery . The second switch-on step S132 is a step in which the controller 15 controls the switch 16 installed between the generator 11 and the second battery group 13 as in the first switch-on step S131 (ON).

In the power generation control step S152, the operation of the generator 11 is stopped after the second switch-on step S132, and power is supplied from the second battery group 13 to the electric load 14 . Since the second battery group 13 is fully charged, the operation of the generator 11 can be stopped to reduce the power required for the operation of the generator 11, so that the improvement in fuel economy can be expected accordingly . Also, by supplying power from the second battery group 13 to the electric load 14, it is possible to reduce the frequent charge / discharge of the first battery group 12, The life of each battery can be prolonged.

The controller determines that the vehicle is not decelerating in the driving state determination step S110 and determines that the charging amount of the second battery group 13 in the second battery charging state determining step S120 is the second non- If it is judged that it is not larger than the battery charge amount (a), the switch-off step S133 is performed. In the switch-off step S133, the controller 15 turns off the switch 16 provided between the generator 11 and the second battery group 13 so that the second battery group 13 is turned off, The circuit connecting the second battery group 13 and the electric load 14 is turned off and the circuit connecting the second battery group 13 and the electric load 14 is also turned off. Therefore, the second battery group 13 can not be charged from the generator 11, and power can not be supplied from the second battery group 13 to the electric load 14.

The first battery accumulation charge amount determining step S141 compares the accumulated charge accumulation amount of the first battery group 12 with the preset no charge control accumulated first charge accumulation charge accumulation amount b, 12) is larger than the no-charging-control-controlled first battery cumulative charging amount (b). The accumulated charge amount of the first battery group 12 is detected by monitoring the state of the first battery group 12 sensed by the sensor 12a installed in the first battery group 12 by the controller 15 .

In the first battery accumulation charge amount determination step S142, the cumulative charge / discharge amount of the first battery group 12 in the first battery cumulative charge amount determination step S141 is determined as the cumulative charge cumulative amount of charge ). The first cumulative charge amount of the first battery group 12 is compared with the cumulative first charge cumulative amount c of the first charge accumulation control of the first battery group 12 in step S142, Charge control entry first battery cumulative charge amount (c). The accumulated charge amount of the first battery group 12 can also be detected by monitoring the state of the first battery group 12 sensed by the sensor 12a installed in the first battery group 12, have.

The no-charge control step S153 is performed when the accumulated charge amount of the first battery group 12 is lower than the no-charge control-entered first battery accumulated charge amount c in the first accumulated battery charge determination step S142 . That is, when the cumulative amount of charge of the first battery group 12 is greater than the first charge accumulation charge amount b of the first charge accumulation control group, 1 < / RTI > battery cumulative charge amount (c). In the no-charge control step S153, the control unit 15 controls the generator 11 to supply power to the electric load 14, and the battery of the first battery group 12 is substantially And controls the voltage of the current output from the generator 11 so as not to be charged. For example, when the current is outputted from the generator 11 to the voltage of the voltage level of the first battery group 12, charging of the first battery group 11 hardly occurs. At this time, since the second battery group 13 is in a state where the switch 16 is off and the control unit 15 stops charging the first battery group 12, charging is not performed , The power output from the generator 11 is directly supplied to the electric load 14 of the vehicle.

The first battery charge control step S154 may include a step S151 of determining whether the cumulative charge / discharge amount of the first battery group 12 in the first battery cumulative charge amount determining step S141 in the first battery cumulative charge amount determining step S141 is greater than the cumulative charge / Control is performed so that power is supplied from the generator 11 to the first battery group 12 and the electric load 14 when the first battery accumulation charge amount b is not higher than the first charge accumulation charge amount b. The control unit 15 controls the first battery group 12 to be charged while the generator 11 is operated. That is, the voltage of the current output from the generator 11 is sufficiently higher than the voltage of the first battery group 12 so that the first battery group 12 is charged. At this time, power is supplied from the generator 11 to the electric load 14, and the second battery group 13 is not charged because the circuit is not connected to the generator 11.

If it is determined that the accumulated charge amount of the first battery group 12 is not lower than the accumulated charge amount c of the first battery group 12, And a cumulative data initialization step (S143) for initializing the charge amount and the accumulated charge amount are performed. After the cumulative data initialization step (S143) is performed, the first battery accumulation charge amount determination step (S141) is returned.

If either the maximum charge control step S151, the no power generation control step S152, the no-charge control step S153, or the first battery charge control step S154 is performed, A key-off determination step (S160) is performed. If it is determined that the key-off is not performed in the key-off determining step S160, the process returns to step S110.
