The field-effect transistor used as a protective element in lithium-ion battery protection boards. To ensure that the battery will not be reconnected to the circuit in case of abnormalities, a special design is made to the circuit. The method is to protect the control part of the circuit. The...

(1) Constant voltage charging method: During the charging process, the output voltage of the charging power supply remains constant. As the state of charge of the lithium-ion battery pack changes, the charging current is automatically adjusted. If the specified voltage constant value is approp...

4. Dimethyl carbonate is a non-toxic, environmentally friendly, and widely used chemical raw material; Simultaneously, it has a high evaporation temperature and a fast evaporation rate. 5. Methyl ethyl carbonate, a colorless and transparent liquid, is a high-tech and high va...

The electrolyte of lithium-ion batteries is the carrier for ion transport in batteries. Generally composed of lithium salts and organic solvents. Electrolyte plays a role in conducting ions between the positive and negative electrodes of lithium-ion batteries, ensuring the advantages of high v...

Correct charging method for ternary power lithium-ion battery pack 1. Use a matching charger to fully charge the ternary lithium-ion battery and then charge it for an hour. 2. Discharge to about 20% remaining before charging, excessive discharge will damag...

◆ Liquid cooling structure heat dissipation method for power lithium battery pack 1. The heat of the battery cell is transferred to the liquid cooling tube through thermal conductive silicon film, and the heat is carried away by the free circulation of thermal expansion and con...

Heat dissipation methods for ternary power lithium-ion battery pack systems There are two types of heat dissipation for lithium-ion battery packs: active and passive, and there is a significant difference in efficiency between the two. The cost required for passive systems is re...

Power lithium batteries are the core of electric vehicles, which are resistant to high temperatures, waterproof, and can withstand freezing. When an electric car cannot be driven, the first thing that comes to mind is that the battery has a problem. Can the ternary lithium-ion battery pack wit...

3. Do not replace the charger casually and do not remove the speed limit of the controller Chargers from various manufacturers generally have personalized needs, so do not replace them casually when unsure. If the required driving range is relatively long, it is necessary to...

1. Placing power supply Lithium ion battery packs have some remaining battery capacity before leaving the factory, and can also be used for short distance cycling after electric vehicles are sold. After the first cycling, the battery needs to be charged for the first time. I...
