POWER SUPPLY SYSTEM FOR VEHICLE

摘要

A power supply system for a vehicle, which executes the following control, is provided. When a connector coupled to an external power supply is connected to the vehicle , a CHR is set to an on state. When a voltage is lower than a threshold, B2 charging process is executed. When the voltage is higher than the threshold and an SOC1 of a first battery is lower than a threshold, a charging device is stopped and both a first SMR and a second SMR are set to an on state, and B1 charging process is executed. When the SOC1 is higher than or equal to the threshold, the charging device is stopped and both the first SMR and the second SMR are set to an off state.

主权项

1. A power supply system for a vehicle, the power supply system comprising:
a first electrical storage device that is a power supply source to an electrical load, the electrical load being a drive source of the vehicle; a converter configured to bidirectionally adjust a voltage between the first electrical storage device and the electrical load; a second electrical storage device that is a power supply source connected to the electrical load in parallel with the converter; a charging device connected to the converter in parallel with the second electrical storage device, the charging device being configured to charge at least one of the first electrical storage device or the second electrical storage device by a power supply outside the vehicle; and a control device configured to control the converter such that the first electrical storage device is charged using electric power from the second electrical storage device and electric power from the charging device, after the second electrical storage device is charged using electric power from the charging device.
