Car battery tester and auto battery charging tool for different batteries

As one of the three components of electric vehicles, the battery is the power source of the entire system. It has always been regarded as an important landmark technology of the development of electric vehicles, accounting for about 30 percent of the vehicle cost. And its performance is also directly related to the length of the vehicle range. Today, I will give you a detailed explanation of the classification, advantages, and disadvantages of automobile batteries, as well as the testing and charging of automobile batteries.

Classification of common automotive batteries

In a broad sense, batteries can be divided into chemical batteries, physical batteries, and biological batteries. Chemical batteries are most widely used in electric vehicles.


In the process of technological development, automobile companies have used different types of batteries, but for the consideration of cost and technology. At present, the vast majority of battery has been eliminated by the market, such as the lead-acid battery, lithium manganese acid battery, and so on. Now the mainstream battery in the market is mainly lithium-ion batteries, a few car companies use nickel-metal hydride batteries, such as Toyota.

Lithium-ion battery

At present, the lithium batteries equipped with electric vehicles in the sale are mainly lithium iron phosphate batteries and three lithium batteries, lithium iron phosphate battery thermal stability, safety, low cost, long life; low energy density, afraid of low temperature. Thermal stability is the best in power lithium-ion batteries. The biggest pain point lies in low-temperature charging. When the temperature is below -5℃, the charging efficiency is low and it is not suitable for charging in cold areas.

The ternary lithium-ion battery has high energy density, long cycle life, and no fear of low temperature. Insufficient stability at high temperatures. The disadvantage is that the deoxidation temperature of ternary material is 200℃, and it can not pass the needle test, indicating that the ternary battery is easy to cause combustion, explosion, and other safety accidents in the case of internal short circuit and battery shell damage.

Ni-MH Batteries

Nickel-metal hydride batteries are often used in hybrid vehicles. One advantage of nickel-metal hydride batteries is that they are more stable than lithium-ion batteries, but their packs are larger. Moreover, the capacity of the NIMH battery will attenuate in the cycle charging and discharge process. Excessive charging or discharging may aggravate the capacity loss of the battery.

Tool for car battery detection and charging

AUTOOL BT380 is an instrument that supports vehicle battery testing and charging. It uses the most advanced conductance measurement technology to easily, quickly, and accurately test the vehicle start system, vehicle charging system, and vehicle battery, and can charge the 12V vehicle battery. It supports multiple languages, including Japanese, English, Russian, German, Spanish, Polish, Portuguese, Korean, and other languages that can also be customized according to user needs. It is also suitable for a variety of batteries and can be tested on all 12V vehicles with start systems, charging systems, and start lead-acid batteries, including ordinary lead-acid batteries, AGM flat-panel batteries, AGM spiral batteries, and colloidal batteries. As long as the charging line is connected to the 220V power interface, you can choose four functions to charge the car battery, battery charging test, start the test, and charge test.
