Intelligent monitoring and repairing device for automobile storage battery

Abstract

The invention relates to an intelligent monitoring and repairing device for an automobile storage battery, is convenient to use and can realize rapid charging between a standby battery and the automobile storage battery in positive and reverse directions. The intelligent monitoring and repairing device for the automobile storage battery comprises a main control processor, a voltage monitoring circuit, a charging management circuit, a DC-DC conversion circuit, the standby battery and a switch circuit. The automobile storage battery with an insufficient voltage for start of an automobile can be charged through the equipped standby battery to make the voltage of the automobile storage battery increase to have enough electric quantity to start the automobile in the relatively short time. When the automobile storage battery is in fault or is over the service life, a state of the automobile storage battery can be comprehensively analyzed and determined according to a charging and discharging current, the capacity and a voltage curve of the automobile storage battery, and a fault prompt can be provided for a user to rapidly replace the automobile storage battery. If the automobile storage battery is in a fake fault only because of lack of electric quantity after long-term idleness, a slow trickle current charging mode is first provided for a while, and a proper rapid charging current mode can be provided to automatically restore functions of the automobile storage battery after the automobile storage battery recovers.

Description

technical field [0001] The invention relates to a power bank, in particular to an intelligent device for monitoring and repairing the use state of an automobile storage battery. Background technique [0002] When the car battery is dead, the common practice in the past is to go to the repair shop to charge it for a few hours, and then there is an emergency starter power supply for cars, which has a history of two or three years. This kind of emergency starter power supply is installed in a shell Several ordinary lithium batteries are connected in series. When in use, directly use two wire clips to charge the battery in such a way that the positive and negative poles of the emergency starter power supply are connected to the positive and negative poles of the car battery. [0003] There are following deficiencies in using the above-mentioned emergency starting power supply: [0004] 1) When connecting the emergency starting power supply to the car battery, it is easy to caus...

AI Technical Summary

Problems solved by technology

[0004] 1) When connecting the emergency starting power supply to the car battery, it is easy to cause some people to be injured

[0005] Many drivers only know how to drive, and they don’t know where the car battery is, let alone the positive and negative poles of the battery. Especially for women, if the positive and negative poles are connected incorrectly, the consequences will be very serious. The battery exploded, causing casualties

[0006] 2) Troublesome operation

[0007] When connecting the emergency start power supply to the car battery, first open the front cover of the car, use tools to loosen the nuts on the positive and negative poles of the battery, and then connect the clips on the emergency start power supply to the corresponding electrodes and tighten them. But, so, when the tool cannot be found, the above-mentioned connection operation cannot be performed with bare hands, which is a very troublesome thing for most drivers who only know how to drive and do not maintain well

[0008] 3) In some special cases or harsh environments, when the battery is out of power, it is very inconvenient to use the above-mentioned emergency start-up power supply, such as getting off the vehicle in cold winter and in the wild where you can't see your fingers, it is very inconvenient, such as on viaducts, chain bridges, Operation is not possible in areas where disembarkation is prohibited, such as highways or safari parks

[0009] 4) It takes a long time to connect the emergency start power supply to the car battery. It takes more than ten minutes at the fastest from opening the front cover, connecting to closing the wire

[0010] 5) When the lithium battery in the emergency starting power supply is low, it needs to be taken out and charged elsewhere, which is very cumbersome
