The safety performance test content of lithium battery includes overcharge, short circuit, drop, heating, vibration, squeeze, acupuncture, heavy object impact, etc.  Only after passing these tests can lithium batteries be truly installed on new energy vehicles and used by consumers. So why is the overcharge test so important?

Battery overcharging is probably one of the most common problems people encounter .

For example, Overcharging your car battery is especially dangerous because it’s difficult to notice, and when it happens, the results can range from mild to the more disastrous. 

Specially designed overcharge test machine is more suitable for safety battery test.

GESTER Battery Overcharging testing machine is mainly used for battery overcharge and discharge, charge and discharge test, the battery placed in the explosionproof box, external charge and discharge tester, for the operation of personnel and equipment protection.

Overcharge test principle

Fully charge the lithium battery, and then perform an overcharge . When the battery is overcharged, the voltage rises to a certain voltage and stabilizes for a period of time. When it approaches a certain time, the battery voltage rises rapidly, and when it reaches a certain limit , The battery top hat is pulled off, the voltage drops to ov, and the battery does not catch fire or explode.

Overcharge test machine Feature

1. 4 ranges, High acquisition frequency, high accuracy
2. Independent control
3. Power-off data protection, Off-line operation mode.
4. User-defined protection conditions, such as upper and lower limited current/voltage, delay time, temperature, etc.

GESTER Battery test chamber is made of steel material with good texture and anti explosion effect. We are aimed at providing total testing solutions for various industries. Accordingly, we have set up several independent laboratories.
