Lithium battery power detection method1. Voltage testing method: It means that the power of a lithium battery is obtained by simply monitoring the voltage of the battery. The power and voltage of lithium batteries are not linearly related, so this testing method is not accurate, with a power measure...

With the promotion of energy conservation and environmental protection in society, more and more environmentally friendly products are being applied to the market. In the battery industry, ternary lithium batteries quickly occupied the market with numerous advantages and gradually replaced tradition...

The IEC standard cycle life test for lithium batteries is:After discharging the battery at 0.2C to 3.0V/Charge at 1.1C constant current and constant voltage to 4.2V with a cut-off current of 20mA, let it sit for 1 hour, and then discharge at 0.2C to 3.0V (one cycle)After 500 cycles, the capacity sho...

Nowadays, people objectively have to choose between two technologies when purchasing new energy vehicles: lithium iron phosphate batteries and ternary lithium batteries. Industry insiders tell us that ternary series should be chosen for those who value endurance and vehicle lightweighting, while lit...

1、 Voltage related faults1. High battery voltage: After being fully charged and idle, the voltage of a single or several battery strings is significantly higher, while other individual cells are normal.Reason for malfunction: ① Collection error; ② LMU balance function is poor or ineffective; ③ T...

When using lithium batteries, it should be noted that the battery enters a sleep state after being left for a period of time, at which point the capacity is lower than normal and the usage time is shortened accordingly. But lithium batteries are easy to activate, as long as they undergo 3-5 normal c...
