Abstract

Provided is a starting control device of an electric vehicle. The device can perform a briaging starting to charge a main battery (4) and an auxiliary battery without additionally providing with the number of the parts. A socket (44) receives charging voltage and auxiliary voltage of the main battery from an external power supply.A charging line (Lch) connects the charging voltage to the main battery (4), auxiliary power supply lines (L5, L6) connect the auxiliary voltage to a vehicle drive control unit (452). A main switch (9) is provided on a constant line (L4) for inputting the output of an electric power converting unit (6) to the vehicle drive control unit (452).The vehicle drive control unit (452)includes an electric power converting unit starting unit (75) started when the auxiliary voltage (5) is applied to output a starting signal (ST) of the electric power converting unit (6), and means for maintaining the starting signal (ST) to charge the sub-battery with the electric power from the electric power converting unit (6) when the voltage applied from the electric power converting unit (6) through the main switch (9) to the vehicle drive control unit (452) is a predetermined value.

Description

technical field [0001] The present invention relates to a starting control device for an electric vehicle, and more particularly to a high-voltage main battery that supplies power to an electric motor (hereinafter, simply referred to as "motor") as a driving source of the vehicle, and to an electric drive device other than the electric motor installed in the vehicle. (Auxiliary equipment) A starting control device for an electric vehicle that is powered by a low-voltage secondary battery. Background technique [0002] Generally, an electric vehicle has a high-voltage main battery that supplies power to a vehicle running motor and a low-voltage sub-battery that supplies power to in-vehicle devices other than the motor. The high-voltage power from the main battery is converted to low voltage by a power converter (DC-DC converter) and supplied to the sub-battery, thereby charging the sub-battery. On the other hand, in a structure in which the vehicle drive control unit is driv...
