1. Electrical detection: overcharge, overlapping, external matrix, forced discharge, etc. 2.

Mechanical detection: Falls, impact, glue, vibration, extrusion, acceleration. 3. Hot detection: fire, sand bath, hot plate, thermal shock, oil bath.

4. Environmental detection: antihypertensive, height, soaking, gas resistance, etc. 5.

Capacity detection: 18650 lithium ion battery capacity detection is parameter with full charge voltage and set, because the lowest discharge voltage of the lithium ion battery is 2.75V, so the voltage of less than 3V has been detected on lithium ion battery No meaning; the fixed current discharge is generally used, and the lithium ion battery is generally detected with 0.5c discharge.

6. Safety performance detection: Lithium ion battery safety performance can be qualitatively and quantitatively evaluated by the heat decomposition of the battery thermal out of control. The amount of exothermic rate and cumulative heat dissipation of the battery at different temperatures are parameters of the thermostability of the battery.

Many times, using battery power supply, pure battery power supply! Instead of, for example, RTC real-time clock power-off protection! When doing millimeter wave battery power supply project, according to project requirements, the battery sample supplied is finely detected. : 1. From the baler, discharge.

One record data per minute! Until the discharge to the target value, then 10 detection points. 2. Discharge current maximum 2.

87A, minimum 1.353A! --- Target is to maintain output power at 5.5 W or more!.
