Intelligent system preventing power lack for automobile battery

Abstract

The invention discloses an intelligent system preventing power lack for an automobile battery. The intelligent system comprises an ECU, an engine, an electric generator, a gear switch and a storage battery, the ECU is electrically connected with the engine which is connected with the electric generator, the electric generator is connected with the storage battery, and the storage battery and the gear switch are connected with the ECU respectively. According to the intelligent system, the ECU adopts normalizing for power supply, battery voltage is monitored in real time, when the battery voltage is lower than a safe value, and an automobile is in a safe state, the electric generator is started to charge the battery, wherein the safe value varies according to different batteries; after charging is completed, the storage battery voltage is monitored continuously, and circulation detection and circulation charging are achieved. In this way, the intelligent system has the following advantages that the battery voltage is monitored in real time, intelligent charging is conducted, and the problem of power lack of the battery is solved; power lack of the battery is prevented, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to an intelligent system for preventing power loss of an automobile storage battery. Background technique [0002] As the power supply of the vehicle electronic system, the battery is related to the normal operation of all electronic systems. If the vehicle is parked for too long, since the ECU (vehicle controller) and the anti-theft system of the vehicle are still working normally when the vehicle is parked, there may be a power loss and the engine cannot be started. Some car owners forget to turn off the lights or the car entertainment system after parking. If the time is too long, the vehicle will also lose power. Battery loss is not only inconvenient to recharge but also affects the service life of the battery. [0003] current technology: [0004] When the battery loses power and the vehicle cannot be started, the existing method is usually to use another battery to help it. [0005] Prior art mainly has following shortco...

AI Technical Summary

Problems solved by technology

[0006] 1) The battery voltage cannot be monitored, and the battery loss cannot be predicted in advance;

[0007] 2) The power supply process is cumbersome, time-consuming and labor-intensive, and cannot be intelligently replenished;

[0008] 3) It is not possible to replenish the power in advance, and the battery will lose power, which will easily damage the life of the battery
