How to check whether the lithium battery capacity reaches the standard

The method to test whether the capacity of lithium batteries meets the standard is: use battery capacity tester, use multi-purpose tester, use battery management software, use a multi-purpose battery charger, and using a multimeter.

1. Use a battery capacity tester: This is the most commonly used method. Using a battery capacity tester can quickly and accurately detect whether the lithium battery capacity reaches the standard. Simply insert the lithium battery into the tester to read the battery capacity information.

2. Use a multi-purpose tester: A multi-purpose tester usually has multiple functions such as testing voltage, current, resistance, capacitance, etc. By selecting the corresponding test function, the lithium battery capacity information can be testedés.

3. Use battery management software: Some battery management software can help users detect the capacity information of lithium batteries. This method usually requires installing software on the computer and connecting the battery to the computer.

4. Use a multi-purpose battery charger: Some multi-purpose battery chargers can detect battery capacity information. Select the corresponding test function on the charger to test the battery capacity information.

5. Use a multimeter: A multimeter can also be used to test battery capacity information. Set the multimeter to the DC voltage range and connect the positive and negative terminals of the battery to the corresponding positions on the multimeter to read the battery voltage information. Then calculate the informationmations on battery capacity based on standard lithium battery voltage and capacity formulas.

How to check whether the capacity of lithium battery is qualified?

Cannot be measured. The number of volts of an electric vehicle battery is usually marked on the case. If the mark is not visible, the battery V number can be calculated based on the number of internal batteries.

The voltage of a single battery is 12 V. When three batteries are connected in series, it is 36 V. When four batteries are connected in series, it is 48 V. When five batteries are connected in series, it is 36 V. 60V. There are also voltages for a single battery, i.e. 16V.

How to maintain the electric vehicle battery and use the charger correctly:

1. Determine whether the mains power and input voltage of the charger areconsistent.

2. Determine whether the charger's output voltage matches the battery's nominal voltage.

3. First plug in the plug connecting the charger to the battery box, then plug in the AC power plug.

Lithium battery capacity refers to the amount of electricity it can hold. The unit is usually "ampere-hour" or "milliampere-hour". For example: the capacity of a lithium battery is 500 mAh, which means that if the battery current is 10 mA in operation, it can work continuously for 50 hours.

Lithium battery capacity test is based on full charge voltage and termination voltage set as parameters. Since the minimum discharge voltage of the lithium battery is 2.75 V, therefore a voltage lower than 3 V makes no sense. Lithium battery testing; Fixed current discharge is generallyexpressed in C, and lithium batteries are generally tested with a discharge of 0.5 C.

1.Charge the battery fully. The voltage of a single lithium battery after fully charged is 4.2V;

2. Use a multimeter to set the constant current of the lithium battery to 0.5C relative to the battery capacity. , and set the final tension. is 3 V;

3. Multiply the constant current discharge time by the discharge current to obtain the battery capacity; check: If the constant current discharge cannot reach two hours, then the rated value; the voltage is not sufficient and the lithium battery risks counterfeiting.

After the lithium battery capacity test is completed, performance tests, electrochemical tests and other items should be carried out. During the testing process of 3C lithium batteries, battery test modules and modulesHigh current shrapnel microneedling can be performed. be used as connections. The conductive bridge can transmit large currents of 1-50A, and its performance is stable and reliable, which is conducive to stable testing.
