Problems solved by technology

And when we use the charging gun to charge the power battery, it is impossible to charge the starter battery at the same time
This will cause the small battery to lose power during the use of the electric vehicle

Abstract

The invention provides a device and method for charging a starting power supply of an electric vehicle. The device comprises a vehicle socket CLCZ, a power storage battery DL, a DC-to-DC module DC / DC, an intelligent battery sensor IBS, a starting storage battery XD, a battery management module BMS and a starting power supply charging relay K1. When the battery management module BMS detects that the electric quantity of the starting storage battery XD is insufficient through the intelligent battery sensor IBS, the starting storage battery charging relay K1 is switched on to charge the starting storage battery XD. The charging device has the advantages that when the electric automobile is charged fast and slowly, the starting storage battery can be effectively charged, the situation that the automobile is in danger due to the fact that the starting storage battery is lack of electricity is prevented, the overall structure is simple, and reliability is high.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a device and a method for supplementing power from a starting power supply of an electric vehicle. Background technique [0002] Unlike traditional gasoline vehicles, electric vehicles have two sets of electrical systems, high voltage and low voltage. The high-voltage electrical system is the power battery, which is mainly used to drive the motor of the car. It is mainly used for a long period of medium-current continuous discharge, and occasionally for high-current discharge (starting, accelerating), and is used in a deep cycle, as well as power supply for high-power subsystems. . The low-voltage electrical system, that is, the general starting battery, is what we often call a 12V small battery. It is usually used in low-power subsystems of automobiles, such as double flashing, lighting, instrumentation, central locking, and for vehicle controllers, motor control systems, Th...
