Lithium battery assessment test project
Definition
Full charge: to achieve the specified capacity of the manufacturer, charge the battery under the manufacturer's recommended charging conditions (including current, voltage, temperature, time, etc.). Furthermore, the time required for the battery is within a week after the charge.

Complete discharge: discharge under the recommended discharge conditions (including current, temperature, etc.) by the manufacturer, and on the battery according to the specified discharge voltage. And the time required for the battery is within a week after the discharge.

A newly produced battery: the requirement for the battery is less than a month after production and is accepted less than the XX charging cycle.

Battery cycle: according to the manufacturer's recommended conditions, the battery is continuously charged and discharged, and the discharge capacity of the battery has been reduced by 40% to 60% at the manufacturer's designated capacity.

Indoor temperature: in the test, the room temperature is 20 + 5 degrees, which is the temperature in the ordinary room. The setting value is based on a simple test environment.

Explosion: an explosion is an explosion or damage to the inside of the battery or the part of the battery shell that is split open.

Fire: fire is caused by spontaneous combustion or burning inside the battery.

Safety valve operation: the meaning of the operation of the safety valve refers to the discharge of the battery during the normal use of the battery (releasing the internal pressure of the battery to the outside world).

Deformation: the deformation refers to the visible and visible deformation of the cell caused by external pressure or internal pressure.

Evaluation test project

（1）Electrical test
Standard test method standard for battery condition temperature assessment of test items
1．The external short circuit is fully charged. The newly produced battery is at room temperature of 60 degrees, and the wire with resistance less than 50m ohm is short circuited for 6 hours.
2．The normal room temperature of the battery at the normal room temperature after the full charge discharge is 250%. * if the safety or protection function is achieved during the test, the test of no explosion and no fire can be terminated.

3．Continuous charging, fully discharged, just finished battery is charged at the normal room temperature according to the method recommended by the manufacturer, and there is no explosion, no ignition and no split in the specified voltage for 28 days.

4．The full discharge of excess charging has been charged to 250% of the calculated capacity at the normal room temperature of the battery produced by the manufacturer. * if the safety or protection function is achieved during the test, the test of no explosion and no fire can be terminated.
5．The battery is discharged at high current and discharged completely. The battery is just under normal room temperature. The battery charge is 3 times that recommended by the manufacturer, and the current is charged to the battery. The capacity of the battery is over 100%, no explosion and no fire.
（2）Mechanical performance test

Standard test method standard for battery condition temperature assessment of test items
1．The battery that vibrate completely or completely discharged is vibrating at normal room temperature for 90 to 100 minutes in three directions of XYZ, the amplitude is 0.8mm, the frequency is 10HZ, and the frequency change rate is 1HZ/min. After the test, the full discharge battery will be charged to the full capacity recommended by the manufacturer. No explosion, no fire, no deformation
2．The acceleration is completely charged or fully discharged. The normal production of the battery is accelerated at the initial time of 3 milliseconds, and the average acceleration is 75g (G is the gravity acceleration unit). The peak time is 125-175g. Vibrate in the direction of each XYZ perpendicular to each other. After the test, the full discharge battery will be charged to the manufacturer's recommended capacity. No explosion, no fire, no deformation
3．The battery that is completely or completely discharged at the normal room temperature is free to drop 10 times from the 1.9m high to the cement ground. After the test, the full discharge battery will be charged to the manufacturer's recommended capacity. No explosion, no fire phenomenon (small battery drop test machine BE-F-320S, Baer brand)
4．The nail is fully charged through the battery and is fully charged at the normal room temperature of the battery. The nail in diameter 2.5 to 5mm through the longitudinal axis of the battery * puts the nail into the battery 6h. No explosion, no ignition (battery needle test machine BE-9002)

5．The battery is fully charged, and the battery is just released at normal temperature. The battery is placed between two flat iron plates, so that the vertical axis of the battery is parallel to the flat iron plate. Then the 13kN pressure is applied to the battery without explosion or ignition. (battery extruder, BE-6045).

6. Hit the battery at normal room temperature with a cylindrical stick (7.9MM diameter) over the top of the battery and perpendicular to the longitudinal axis of the battery. 9.1kg has a considerable weight falling down from 61cm. No explosion, no ignition (battery impact test machine BE-6045)

7.10m falls completely at the normal room temperature of the battery that has just finished and will drop the battery to the cement ground at a high level of 10m. No explosion, no fire

（3）Environmental performance test

Standard test method standard for battery condition temperature assessment of test items
1．High temperature storage battery is fully charged just finished production (a) at a temperature of 100 DEG C oven stored in 5 hours after the battery at the temperature of 20 DEG place 24h (b) at 60 DEG C oven after 30 days storage battery will be placed at a temperature of 20 DEG C place 24 hours without explosion, no fire the phenomenon of

2. The heat conflict is fully charged, and the newly completed battery passes through 10 consecutive cycles within 2 hours at the temperature of -20 C and 40 C to shift the battery from -20 to 60 C, and the replacement time does not explode, no ignition, no damage and no deformation in 5 minutes.

3. Low voltage fully charged, just finished battery. At room temperature, the battery is placed at absolute pressure equal to or less than 11.6kpa, time is 6 hours, no explosion and no fire.

(3) II environmental performance test (improper behavior)

Standard test method standard for battery condition temperature assessment of test items

4. Heat is heated and the battery is completely recharged and the battery is put into the oven at a rate of 5 + 2 / min until 130. Put the battery in the oven for about 60 minutes. No explosion, no fire

5. Drop into the water and completely recharge the battery at room temperature and immerse the battery in the water (room temperature) for 24 hours without explosion and fire.
