In order to provide sufficient voltage to the device, lithium battery packs are usually composed of multiple batteries connected in series, but if there is a capacity mismatch between the batteries, it will affect the capacity of the entire battery pack. For this, we need to balance the mismatched b...

What is the purpose of the lithium-ion battery pack balance maintenance device?1. Overcharging maintenance purpose: Overcharging maintenance purpose refers to strictly prohibiting recharging by the charger when a certain working voltage is reached. The MOS transistor that is about to manipulate over...

Attach a parallel balancing circuit to each individual battery in the battery pack to achieve the purpose of shunting. In this mode, when a battery reaches full charge first, the balancing device can prevent it from overcharging and convert excess energy into heat energy, continuously charging the u...

Lithium batteries are known as "rocking chair type" batteries, in which charged ions move between the positive and negative electrodes to achieve charge transfer, providing power to external circuits or charging from external power sources.During the specific charging process, an external...

Can power batteries have both high energy density and ultra fast charging?Micro Macro Power, which was first known for its fast charging batteries, has explored this under current and future technological conditions. At the 2019 Shanghai Auto Show, Weihong Power introduced three batteries specifical...

At present, there are more and more articles promoting the fast charging of power batteries. Some manufacturers' promotions are exaggerated, and some experts also follow the trend, saying that electric vehicles can be charged in 30 minutes or 15 minutes, and even more ridiculous, saying that the...

The new car has been launched, and of course, I am referring to electric vehicles. This introduction often appears: fast charging, 80% charging in half an hour, and a range of 200 kilometers, completely solving your range anxiety! Fast charging is used by commercial vehicles to improve equipment eff...

According to foreign media reports, GBatteries, an unknown YC (Silicon Valley Entrepreneurship Incubator) startup, boldly claims that it can quickly charge electric vehicles like refueling a fuel tank.Silicon Valley GBatteries claims to be able to fully charge a 60kWh battery pack in 15 minutes.GBat...

StoreDot is equipped with dedicated battery packs and charging stations for this technology, and claims to be able to replenish electric vehicles with a range of 480 kilometers in just 5 minutes, which is similar to the time it takes for a traditional car to fill a tank of gas.For this purpose, Stor...

Recently, a German research team discovered the key to capacity loss in lithium-ion batteries and hopes that the research results can provide direction for more efficient battery manufacturing.Scientists from the Technical University of Munich in Germany have found that the active lithium in a singl...
