How to choose the emergency power supply for automobile

How to choose the emergency starting power supply for automobiles At present, almost all automobile batteries use lead-acid batteries, which have a lot to do with their cost and convenient maintenance. Lead-acid batteries still have irreplaceable aspects in the automotive industry. With the extension of use time, the performance of car batteries will also drop sharply. status. This situation is more common in winter. In winter, the battery's performance is greatly reduced by the temperature, and it will be more troublesome if the car cannot be started in the middle. The automobile emergency starting power supply can solve the failure to start due to insufficient power. The automobile emergency starting power supply is also called the automobile mobile power supply in the industry, and its small size is also a feature of the current new type of automobile emergency starting power supply. It not only has the ability to start the car in an emergency, but also can be used as a backup mobile power source to provide power to mobile phones and other electrical equipment. So what kind of battery should be used for car emergency start power supply? 1) The high-safety power lithium battery has high requirements for safety because it needs to be placed on the car for a long time. Once a battery accident occurs, the consequences are very serious. 2) Polymer lithium battery, power-type polymer lithium battery can be compact, light, and powerful. Strong plasticity. 3) Good low temperature performance. Most of the battery lack of electricity occurs in the cold winter, so the utilization rate of the car's emergency starting power supply in winter will be higher. Good low-temperature performance is required. 4) High-rate lithium batteries are used. Generally, the starter motor power of a car can reach 300W, which requires high discharge performance of the starter battery. Only when the discharge performance is satisfied and matched can the start-up be completed. Therefore, it is better to use high-rate lithium-ion batteries for the car's emergency starting power battery. Although there are also rate-type nickel-hydrogen batteries used as power sources. However, compared with the compactness and convenience of lithium batteries, other batteries are irreplaceable.
