In Residential Energy Storage System, the battery management system has two main functions, namely battery protection and battery monitoring.

Battery protection

Detecting various fault conditions and protecting the battery from damage during charging and discharge is the main purpose and function of BMS. The operation of the battery outside its specifications will cause damage to the battery and cause the battery to fail, thereby causing maintenance work and causing a major cost impact. The battery must be closely monitored during the charging and discharge process to avoid these negative effects.

The following protection must be provided:

Over -pressure/under pressure

Pouring current

Reverse current

Short circuit

Designers who adopt the Yingfeeling solution will benefit from:

Wider SOA

Short -circuit protection, with higher rated peak current current

Tailoring to open and close solutions for application needs

Reduce the number of BOM and more effective parallel solutions, so it has cost benefits

Battery monitoring batteries must be monitored and protected by systematic. The battery management system is responsible for monitoring each section in the battery pack and ensuring that they run within the scope of safety. Various parameters (such as battery voltage, SOC, health status (SOH) and temperature) have a decisive effect on the performance, safety and service life of the battery. It is necessary to protect the battery from the impact of external faults that may be in danger. One of the main functions of BMS is to protect the battery from damage during the normal operation of the system (charging and discharge process). In Yingfeeling's product portfolio, the designer will find the appropriate device to disconnect the battery system when detecting the failure, thereby protecting its value will not be damaged. They can also help detect system failures, such as overcurrent and short circuits.
