How to judge which lithium iron phosphate battery is good

Safety factor of lithium iron phosphate battery Among lithium-ion batteries, lithium-ion batteries with lithium iron phosphate as the cathode material have the best safety factor. The important reason is that Lifepo4 has good oxygen-retaining ability under high temperature standards. Even if the temperature is above 500c, it will not lose oxygen, which is much higher than lithium borate, lithium manganate and ternary materials. However, under abuse conditions, even lithium-ion batteries with LiFePO4 as the positive electrode may have safety issues. ... Read More

Electric vehicle lithium-ion battery charging methods and matters

(1) Do not charge in the sun in hot weather, and do not charge immediately after driving. Summer is here, this is especially important, remember not to charge the electric car in the hot sun, nor to put the battery in the sun . In the same way, you should stay away from open flames and high-temperature heat sources both during normal times and when charging. (2) When an electric vehicle is found to indicate that the battery is too ... Read More

What are the precautions for lithium-ion battery balancing

Precautions for balancing lithium-ion batteries It takes a long time to balance lithium-ion batteries during discharge. Since the discharge speed is related to the resistance of the load resistance, the efficiency of balancing is low when the system is working. If balance is performed during discharge and a shorter balance time is desired, an external power transistor with a smaller on-resistance should be connected. This type of transistor is very common, such as MOSFET or FET. If you want to ... Read More
