Abstract

The invention provides an inter-vehicle charging device. The invention provides a small-size low-cost inter-vehicle charging device capable of supplying the charging current suitable for a battery of a rescue object vehicle without using a DC / DC converter for fast charging. A rescue vehicle comprises a battery, an inverter; a motor for driving the vehicle and driven by the inverter; and a control device capable of managing the battery, controlling the inverter and controlling the charging of the batteries of the other rescue object vehicles. The inter-vehicle charging device for charging the battery of the rescue object vehicle using the rescue vehicle comprises a standardized connector for supplying the charging current output from a neutral point of the motor and one bus of positive, negative direct-current buses of the inverter to the battery and receiving and sending a control signal for charging the battery between the control device and the rescue object vehicle, and cables.

Description

technical field [0001] The present invention relates to an inter-vehicle charging device mounted on a vehicle such as an electric vehicle or a hybrid vehicle to charge a battery of another vehicle. Background technique [0002] In order to use vehicles such as electric vehicles or hybrid vehicles with sufficient battery power (hereinafter referred to as rescue vehicles) to rescue so-called electric vehicles such as electric vehicles that cannot run on their own due to exhausted batteries (hereinafter referred to as rescue target vehicles), as vehicles There is an invention described in Patent Document 1 as a prior art for charging and discharging between batteries. [0003] Hereinafter, the above-mentioned prior art will be described. [0004] Figure 19 It shows a main circuit configuration in which a rescue vehicle 101 with a sufficient remaining battery charge charges a rescue target vehicle 102 with a depleted battery. [0005] First, in order to suppress the battery B...
