What is an electric vehicle battery tester? What are the precautions

First of all, the electric vehicle battery has a battery, the red clip clamps the positive electrode. The black clip clamps the negative pole, and then pull the trigger in the middle of the two wires to the right, the pointer will swing to the right (that is, the electric heating wire inside will burn red after a long time), the pointer is located in the blue area and the right side, this The battery is good. Let it go right away. Of course, it will be more accurate to detect when the battery is basically used up. A fully charged battery is difficult to measure accurately. The battery tester is quite a high-current discharge tester. It cannot be measured after the battery is fully charged. When the battery voltage is about 12.5V, the battery voltage above 10V is basically no problem. The maintenance of the battery is very important. If you develop bad habits, it will shorten the service life of the battery or cause damage. General storage batteries can be used for 2 to 3 years. But if the usage is unreasonable, it may be replaced in 3 to 4 months. If you let the battery work when the engine is stopped, you must prevent the battery from losing power, because if it loses power, it is easy to cause damage to the battery. Now there is a technology that can repair damaged batteries, using pulse charging technology to activate the battery electrolyte, and it can continue to be used. But if the power loss is severe, the battery will be scrapped in advance. Through the above understanding, do you know what an electric vehicle battery tester is? I hope it will help you. By the way, the author of Baibai Safety Net will share with you some safety precautions when using the battery tester for electric vehicles to make your operation safer. Safety precautions for electric vehicle battery tester: 1. When using this tester, the ambient temperature should not be higher than 40℃, otherwise it will affect the service life of the tester. 2. When using this detector, the ambient temperature should not be lower than 0°C. If the outdoor temperature is lower than 0℃ and the battery enters a warm room from a cold outdoor, frost may appear in the battery box, so please leave the battery at the indoor temperature for 2 hours before testing. 3. The detector does not have a waterproof design, so water should be prevented from entering the restoration device, and the detector should not be placed in an environment with water vapor and humidity. If you accidentally detect water or humid gas in the instrument. Please put the detector in a ventilated and dry place to dry naturally for 48 hours before using it, but do not bake it. 4. The detector cannot withstand strong continuous vibration and severe impact. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
