Description

A car emergency starter power supply

technical field

The invention relates to an automobile emergency starting power supply.

Background technique

With the development of the times, cars have entered ordinary families, bringing great convenience to people's travel, but they will also encounter many problems. For example, cars cannot be started under certain special circumstances, which will bring great inconvenience to users. Big trouble.

At present, cars generally use batteries to start the engine. When the engine is started, the battery is charged by its own power generation system. Under normal circumstances, the power of the battery can be balanced. However, due to the aging of the car battery, insufficient charging, long-term storage or cold weather, It will lead to insufficient power supply of the battery and the failure of the generator to start normally, which will affect the normal use of the vehicle. If the vehicle is started multiple times at this time, it will also cause certain damage to the battery and starter; in order to solve the above problems, there are currently Emergency start-up power supplies are mainly lead-acid batteries and lithium batteries, but both have self-consumption problems, and will lose power after a period of storage. If the power cannot be replenished in time, it will not be used when an emergency is needed. Therefore, Now it is necessary to design a car emergency power supply, which has a large capacity and can be charged even when the backup power supply is out of power, so as to be used in an emergency.
