The battery system grouping technology is a constantly evolving process, from early lead-acid battery packs to the current mainstream lithium battery packs; From individual applications to multiple group applications; From consumer electronics products to power lithium battery systems, battery group...

As a new type of power technology, lithium-ion battery packs must be connected in series to meet the voltage requirements during use. The uneven performance of individual cells is not solely due to battery production technology issues. Even if the voltage and internal resistance of each battery are...

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...
