Abstract
A charge control method for a vehicle is provided which includes charging a first battery when the vehicle is in an IG ON operational state, maintaining the IG ON operational state and monitoring a second battery voltage. The charge control method further includes charging a second battery, calculating a vehicle speed when the vehicle is in an EV READY state and adjusting the EV READY state of the vehicle to the IG ON operational state when the calculated vehicle speed is less than a predetermined speed.
Claims12
A charge control method for a vehicle comprising:
- verifying with a vehicle controller whether a first battery charging connector is connected to the vehicle;
- charging a first battery when the vehicle is in IG ON operational state when the first battery charging connector is connected;
- maintaining the IG ON operational state after charging the first battery in the IG ON operational state;
- monitoring with the vehicle controller a second battery voltage while maintaining the IG ON operational state;
- and
- charging a second battery with the vehicle controller by engaging the first battery based on the result of monitoring the second battery voltage.
A charge control system for a vehicle comprising:
- a vehicle controller that verifies whether a first battery charging connector is connected to the vehicle;
- a first battery charged when the vehicle is in IG ON operational state when the first battery charging connector is connected and maintaining the IG ON operational state after charging the first battery;
- a second battery voltage monitored by the vehicle controller while maintaining the IG ON operational state;
- and
- a second battery that is charged with the first battery based on the result of monitoring the second battery voltage.
A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
- program instructions that verify whether a first battery charging connector is connected to the vehicle;
- program instructions that charge a first battery when the vehicle is in IG ON operational state when the first battery charging connector is connected;
- program instructions that maintain the IG ON operational state after charging the first battery in the IG ON operational state;
- program instructions that monitor a second battery voltage while maintaining the IG ON operational state;
- and
- program instructions that charge a second battery with the vehicle controller by engaging the first battery based on the result of monitoring the second battery voltage.
