Battery charging system

摘要

A battery charging system includes a battery, a load and a controller to control supply power to be supplied from an external power source to the battery and the load, in accordance with a request charging power and a request load power. The controller limits power supplied from the external power source to the battery to an allowable battery power, and distributes the supply power from the external power source between the battery and the load in a state holding limitation of limiting the supply power from the external power source to the allowable battery power when a request for the supply of power to the load is generated.

主权项

1. A battery charging system, comprising:
a heavy electric line adapted to make electrical connection with an external power source; an in-vehicle battery connected electrically with the heavy electric line and arranged to be charged with power supplied through the heavy electric line; a load connected electrically with the heavy electric line and arranged to receive power supplied through the heavy electric line; a calculating section configured to calculate a charging power allowable by the battery, as an allowable battery power; a battery power requesting section configured to request supply of charging power to the battery; a load power requesting section configured to request supply of power to the load; and a controlling section configured to control supply power to be supplied from the external power source to the battery and the load, in accordance with a request charging power from the battery power requesting section and a request load power from the load power requesting section, the controlling section being configured:
to limit power supplied from the external power source to the battery to the allowable battery power, andto distribute the supply power from the external power source between the battery and the load in a state holding limitation of limiting the supply power from the external power source to the battery to the allowable battery power when a request for the supply of power to the load is generated by the load power requesting section.
