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. Full charge discharge completely recharged the battery at the normal room temperature at the normal room temperature of the factory recommended by the manufacturer to force the depth discharge calculation capacity of 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, full discharge, just finished battery, normal room temperature, according to the method recommended by the manufacturer, and at the specified voltage for 28 days, no explosion, no fire and no split.

4. Full discharge of overcharge and full discharge at the normal room temperature of the battery is charged to 250% of the calculated capacity by the current recommended 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. Main current is fully charged. The battery is completely discharged. The battery that has just been finished is at normal room temperature. The battery charge is 3 times the current 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 whole battery is fully charged or discharged completely. The battery will vibrate 90 to 100 minutes in three directions of XYZ at room temperature, 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 battery that has just been produced is normal at room temperature. It accelerates in the initial 3 milliseconds in time. The average acceleration is 75g (G is the acceleration unit of gravity), and it reaches 125-175g when it reaches the peak. 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 has been completely charged or fully 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. Nails are completely charged through the battery and are fully charged at the normal room temperature of the battery. The nail in diameter 2.5 to 5mm passes through the longitudinal axis of the battery and puts the nail into the battery 6h. No explosion, no ignition (battery needle test machine BE-9002)

5. Squeeze and recharge the battery that is just finished, and put the battery into two flat iron plates at normal room temperature, 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 and no fire. (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
