Why lithium battery charging is first constant current and then constant voltage charging

Mar 19, 2025

03-192025

Lithium batteries adopt a constant current followed by constant voltage charging strategy, which is mainly based on safety and battery life considerations. This strategy not only ensures charging efficiency, but also avoids safety hazards such as dendrite growth, and comprehensively improves charging safety and battery cycle life by about 30%.

What exactly does a battery management system (BMS) manage?

Mar 19, 2025

03-192025

BMS is the "brain" of the battery pack, ensuring the safe and efficient operation of the battery pack through real-time monitoring, status assessment, charge and discharge control, thermal management, balancing management, fault diagnosis and other functions.

Characteristics and grid structure of traditional power system

Mar 18, 2025

03-182025

Our country is making every effort to promote the construction of a new power system, and its core features can be summarized in three keywords： Clean: wind and solar energy are the main power sources, and a diversified supply system is built with hydrogen energy and biomass energy;
2. Intelligent: Through smart meters and AI dispatching systems, a second-level response is achieved, and virtual power plants aggregate distributed resources to participate in grid regulation;Marketization: The national unified power market promotes green power transactions, time-of-use electricity prices guide users to use electricity at off-peak times, and energy storage power stations gain profits through peak-valley price differences.

What is battery pack technology?

Mar 13, 2025

03-132025

Battery pack technology is a technology that assembles battery cells, battery management system (BMS), structural parts, thermal management system and other components into a complete battery system that can be directly powered by energy.

Lithium-ion batteries are mainly used in four fields: consumer electronics, electric vehicles, energy storage systems, and industrial equipment.

Uncover the four core components of lithium-ion batteries

Mar 11, 2025

03-112025

The synergy of the positive electrode energy supply, the negative electrode lithium storage, the electrolyte bridging, and the separator escort can achieve the "efficient cycle" of lithium-ion batteries.

Why do lithium batteries use aluminum as the shell?

Mar 10, 2025

03-102025

The main reasons for using aluminum shells in lithium batteries can be analyzed in detail from the following aspects: light weight, corrosion resistance (especially under positive potential), good conductivity, good processing performance, low cost, good heat dissipation performance, etc.

A new breakthrough in solid-state batteries

Mar 10, 2025

03-102025

On February 25, solid-state battery company ION Storage Systems announced a major breakthrough in its new 40mm × 40mm solid-state battery cells: under the commercial specifications, the battery capacity is increased by 25 times compared with the previous generation, and the charge and discharge cycles exceed 1,000 times without volume expansion, overcoming the long-standing electrode deformation problem of solid-state batteries.
