Hello, I want to ask you a question about batteries. What is the difference between lead-acid batteries used in new energy vehicles and ordinary vehicles?

The differences between lead-acid batteries for new energy vehicles and ordinary vehicles are as follows.

1 the capacity of new energy vehicle batteries is many times larger than that of ordinary ones, in order to increase endurance.

The material of new energy battery plate is lead-calcium alloy, while the material of ordinary battery plate is mainly lead-antimony alloy.

The electrolyte concentration of new energy batteries is lower than that of ordinary lead-acid batteries, which varies from factory to factory. Only in this way can the maximum storage capacity be reflected, and the standard proportion of ordinary cars is 1.28. This is to minimize the internal resistance and provide hundreds of amperes of current instantly, so that the car can start smoothly in severe winter.

The battery of new energy allows deep discharge, and the discharge current ratio is very small, which belongs to small current long-term discharge, and the discharge time can last for more than two hours. Ordinary batteries are discharged with large current for a short time, usually starting the car in cold weather 10 seconds, and heating the car for 2 seconds. If the car breaks down, take a taxi continuously in winter (assuming the starter won't burn out) and turn the key for at most 5 minutes, and the electricity will be completely used up.
