What is the 16-cell lithium-ion battery active balance reference design?

The 16-Cell Lithium-Ion Battery Active Balance Reference Design describes a complete solution for high current balancing in battery stacks used for high voltage applications like xEV vehicles and energy storage systems.

What type of batteries are used in energy storage cabinets?

Lithium batteries have become the most commonly used battery type in modern energy storage cabinets due to their high energy density, long life, low self-discharge rate and fast charge and discharge speed.

How to solve current balancing between Battery strings connected in parallel?

Currently, there are two solutions in the industry to solve the problem of current balancing between battery strings connected in parallel: passive selection and active current balancing. Current imbalance in batteries connected in parallel is mainly caused by diferences of cell parameters such as SOC, SOH, and internal resistance.

How does bidirectional power control affect battery current imbalance?

For new batteries of a same batch, after bidirectional power control is added, the cell current imbalance decreases from 20% to 2%, which can be completely decoupled from cell parameters.

What is bsm48106h battery management system?

The BSM48106H features a three-level Battery Management System (BMS) that monitors and manages critical cell information, including voltage, current, and temperature. Additionally, the BMS balances charging and discharging processes to enhance cycle life.

How to design an energy storage cabinet?

The following are several key design points: Modular design: The design of the energy storage cabinet should adopt a modular structure to facilitate expansion, maintenance and replacement. Battery modules, inverters, protection devices, etc. can be designed and replaced independently.
