Abstract
A charging and discharging system includes: a rotary electric machine being able to output a driving force for traveling; a drive circuit unit for supplying electric power of a main battery to drive the rotary electric machine, and charging the main battery through regeneration of the rotary electric machine; and a control unit for controlling the drive circuit unit. The charging and discharging system is configured not to charge a backup battery connectable to the drive circuit unit through regeneration of the rotary electric machine.
Claims7
A vehicle charging and discharging system, comprising:
- a rotary electric machine being able to output a driving force for traveling;
- a drive circuit unit for supplying electric power of a main battery to drive the rotary electric machine, and charging the main battery through regeneration of the rotary electric machine;
- a control unit for controlling the drive circuit unit, wherein a backup battery connectable to the drive circuit unit is not charged by regeneration of the rotary electric machine;
- a normal charging circuit unit connected to a normal charger and being able to charge the main battery;
- and
- a rapid charging circuit unit connected to a rapid charger being able to supply electric power larger than electric power of the normal charger, the rapid charging circuit unit being able to charge the main battery, wherein
- the backup battery is chargeable only from the normal charging circuit unit.
A vehicle charging and discharging system, comprising:
- a rotary electric machine being able to output a driving force for traveling;
- a drive circuit unit for supplying electric power of a main battery to drive the rotary electric machine, and charging the main battery through regeneration of the rotary electric machine;
- and
- a control unit for controlling the drive circuit unit, wherein:
- a backup battery connectable to the drive circuit unit is not changed by regeneration of the rotary electric machine, and
- when a remaining charge amount of the main battery becomes equal to or less than a predetermined remaining amount, the control unit brings the drive circuit unit into a state in which the rotary electric machine is drivable by supplying electric power of the backup battery.
