Abstract

There is provided a distributor of an electric automobile in which the number of switch devices and opening and closing devices is reduced without a sacrifice of functions to thereby simplify and make small a structure. The distributor 10 includes contacts 12P and 12N for cutting off or connecting a driving circuit 68D of an air conditioner 68 and a DC-to-DC converter 66 from or to a main battery 64, electromagnetic coils 12RP and 12RN for opening and closing the contacts 12P and 12N, and a control terminal 12C for controlling the electromagnetic coils 12RP and 12RN.

Claims

1. A distributor for an electric automobile comprising converter switch means for cutting off or connecting a DC-to-DC converter from or to a main battery, converter switch actuating means for opening and closing said switch means, a converter control terminal for controlling said converter switch actuating means, pre-charge switch means which shares a portion of said converter switch means for cutting off a driving circuit of a drive motor from said main battery or for connecting said driving circuit to said main battery through a resistor, pre-charge switch actuating means for opening and closing said pre-charge switch means, and a pre-charge control terminal for controlling said pre-charge switch actuating means.

2. A distributor of an electric automobile comprising pre-charge switch means for cutting off a driving circuit of a drive motor from a main battery or connecting said driving circuit to said main battery through a resistor, pre-charge switch actuating means for opening and closing said pre-charge switch means, a pre-charge control terminal for controlling said pre-charge switch actuating means, discharge switch means provided between said driving circuit and said pre-charge switch means for connecting terminals of said driving circuit with each other through a resistor and for cutting off the connection between two terminals of the driving circuit, discharge switch actuating means for opening and closing said discharge switch means, and a discharge control terminal for controlling said discharge switch actuating means.

3. A distributor of an electric automobile comprising a charging input terminal for connecting a charger, converter switch means for cutting off or connecting said charging input terminal and a DC-to-DC converter from or to a main battery, converter switch actuating means for opening and closing said converter switch means, and a converter control terminal for controlling said converter switch actuating means.
