Abstract

The present invention provides a charging system for an electric vehicle, capable of preventing generation of a short-circuit current even if short circuit occurs at a vehicle side charging lead. A charging system (10) for an electric vehicle (12) is arranged on vehicle side charging leads (46p, 46n) between a vehicle side charging connector (30) and an electrical storage device (24), and has a diode (32) for preventing a backflow current from the electrical storage device (24) to a charging device (14).

Description

technical field [0001] The invention relates to charging systems for electric vehicles. Background technique [0002] A charging system for an electric vehicle is known (Patent Document 1). In Patent Document 1, when charging, the charging port 1 is connected to an external charger, and the drive battery 3 is charged from the external charger ( figure 1 , paragraphs [0009], [0010]). Charging port 1 is connected to driving battery 3 via power supply lines L1 , L2 between charging port 1 and driving battery 3 , and power supply lines L3 , L4 between inverter circuit 2 and driving battery 3 . Charging relays 4a, 4b are provided on the power supply lines L1, L2, and main relays 5a, 5b are provided on the power supply lines L3, L4 ( figure 1 , paragraph [0009]). During charging, the charging relays 4a and 4b are turned on (connected state), and the output of the external charger connected to the charging port 1 is supplied to the drive battery 3, thereby charging the drive ba...
