Embodiment Construction

[0015] like figure 1 As shown, the electrical equipment control method for preventing the vehicle battery from feeding power of the present invention uses a combination meter to monitor the vehicle battery voltage, and disconnects the high-power electrical equipment that does not affect the safe operation of the vehicle when the vehicle voltage is lower than 23.5V. . Specifically, the opening condition of the high-power electrical equipment is: the vehicle voltage ≥ 23.5V and the equipment switch is turned on; the closing condition of the high-power electrical equipment is: the vehicle voltage is <23.5V or the equipment switch is turned off.

[0016] like figure 2 Shown is a schematic diagram of the system of the embodiment. In this embodiment, there are a total of four electrical equipments M1~M4. The equipment switches K1~K4 of each electrical equipment are respectively connected in series with a relay J1~J4. The battery is connected in series with a manual power switch S...

Abstract

The invention discloses an electric equipment control method for preventing a storage battery of a whole vehicle from feeding. The method comprises the following steps: monitoring the voltage of the storage battery of the whole vehicle by using a combination instrument, and disconnecting high-power electric equipment which does not influence the safe operation of the whole vehicle when the voltageof the whole vehicle is lower than 23.5 V. The starting conditions of the high-power electric equipment are as follows: the voltage of the whole vehicle is greater than or equal to 23.5 V, and an equipment switch is turned on. The turn-off condition of the high-power electric equipment is that the voltage of the whole vehicle is less than 23.5 V or an equipment switch is turned off. High-power electric equipment which has no influence on safe operation of the whole vehicle is selected, overshoot and overdischarge of the storage battery are avoided, the service life of the storage battery is prolonged, and feed of the storage battery of the whole vehicle is prevented from influencing starting of the vehicle and normal operation of other equipment.

Description

technical field [0001] The invention relates to the field of vehicle batteries, in particular to a control method for electrical equipment preventing the vehicle battery from feeding power. Background technique [0002] Vehicle electrical equipment is increasing day by day, especially high-power electrical equipment (such as air conditioners, refrigerators, water dispensers, microwave ovens, etc.) Larger loads, if no corresponding management measures are taken, will often cause the vehicle battery to feed power, affecting vehicle startup and battery life. Contents of the invention [0003] The object of the present invention is to provide a control method for electrical equipment that prevents the battery from feeding power to the vehicle, to control the high-power electrical equipment that does not affect the safe operation of the vehicle, to avoid overcharging and over-discharging of the battery, and to affect the service life; The car battery feeds power, affecting the...
