First of all, the battery of emergency starting power can not only start the car, but also charge other electronic digital appliances. In fact, the automobile emergency starting power is also called multi-functional automobile emergency starting mobile power in the industry. It has the characteristics of traditional automobile starting power and has been improved by technology. Combined with the current mobile power, it is more compact and portable.
The new auto emergency starting power integrates the advantages of traditional auto emergency starting power and mobile phone power. It can not only start the car, but also charge the mobile phone, tablet computer, laptop computer and vehicle supplies. And it's about the same size as a mobile phone. So what kind of battery is applicable to the emergency starting power of the car?
We know that there are many mobile power sources on the Internet that claim to be able to start the car. Some car owners suspect that the output current of small mobile power sources is not enough. How can they drive the starter? In fact, the principle of mobile power starting the car is a little different from the traditional way.
The battery of the rescue vehicle cannot be connected in a positive and negative way, otherwise it will generate a huge charging current and burn out the equipment. The way of mobile power rescue is to use the battery of the original car as a huge capacitor. Mobile power charges the battery. After the battery is loaded, the current needed for starting can be generated at the moment of starting.
It is equivalent to releasing the power of long-term charging of mobile power in an instant. The power consumption required for a single start is very small. A mobile power of 10Ah, in theory, if the energy is transferred to a 60A battery, the battery can be charged from 0 to 3% of the state of charge, and then the battery has the opportunity to start the car.
Therefore, the battery used in the emergency starting power should be lithium-ion battery with high rate. The high-performance polymer lithium-ion battery is built in the emergency start-up power of automobile, which is not comparable to ordinary lead-acid battery. The lead-acid battery is large and heavy, which is not conducive to carrying out and using, nor to life application; the service life of the emergency start-up power of automobile is long, and the charge and discharge cycle can be more than 500 times.
