Embodiment Construction

[0012] The automatic charging device for the storage battery of a stationary electric vehicle according to the present invention is introduced below through an embodiment.

[0013] refer to figure 1 , the power battery 1 of the electric vehicle is connected to a DC-DC converter (DC-DC), the output voltage of the power battery is 380V, and the DC-DC converter (DC-DC) 2 can convert the 380V DC voltage output by the power battery The 12V DC voltage for charging the storage battery 3; the start switch 4 of the electric vehicle is connected to the control circuit 5, when the start switch 4 is set to the ON state, that is, when the car key is turned to the ON gear, the control circuit 5 is directly connected to the DC- DC converter (DC-DC), through the DC-DC converter (DC-DC), the 380V DC voltage output by the power battery is converted into 12V DC voltage to charge the battery. When the electric vehicle is parked for a long time, start the switch 4 In the closed state, the control...

Abstract

The invention relates to an automatic charging device for a static electric automobile storage battery, which comprises a direct current-direct current (DC-DC) converter, a charging control circuit and an automobile startup switch, wherein the DC-DC converter is connected with an automobile power battery; the charging control circuit, under the condition that the automobile startup switch is turned on, is connected with the DC-DC converter directly to enable the DC-DC converter to work and charges the storage battery by using the power battery of an automobile, and the charging control circuit, under the condition that the automobile startup switch is turned off, detects the voltage of the storage battery automatically, and when the voltage of the storage battery is overlow (lack of power), triggers the working of the DC-DC converter and charges the storage battery by using a vehicle-mounted power battery; and the automobile startup switch is used for starting or turning off the engine of the automobile.

Description

technical field [0001] The invention relates to an automatic charging device for a storage battery of a stationary electric vehicle. More specifically, the present invention relates to a system that uses the power battery (nominal voltage of 380V) of an electric vehicle to automatically charge the storage battery. The problem of the battery failing to start normally. Background technique [0002] Automobiles have been around for hundreds of years. However, after many years of development, the power of automobiles still mainly uses gasoline or diesel oil (collectively referred to as fuel oil) as fuel, and the energy released by the combustion of fuel is used as power to drive automobiles. However, as the number of automobiles in the world continues to rise, automobiles powered by fuel combustion have also brought about environmental pollution. And more importantly, the rapid consumption of automobile fuel has led to a continuous rise in fuel prices and a rapid increase in v...
