AI Technical Summary

Technical Problem

The existing method of setting protection values in residential battery systems using a dual in-line package (DIP) switch is inconvenient and time-consuming, requiring on-site disassembly and assembly, which places high demands on installers.

Method used

A battery system with a processing circuit, constant current source, and multiple battery packs, each equipped with sense resistors, allows for the direct representation of voltage protection values through the connection of sense resistors in series with the constant current source, eliminating the need for on-site adjustment with a DIP switch.

Benefits of technology

This approach simplifies the setting of protection values, reducing installation time and labor costs while enhancing safety and convenience by allowing the voltage of the constant current source to directly reflect the protection value corresponding to the number of connected battery packs.

Abstract

The present application discloses a battery system and a power supply system. The battery system comprises a processing circuit, a constant current source and a plurality of battery packs; each battery pack comprises at least one sampling resistor; the sampling resistors of all the battery packs are connected in series across the constant current source; voltages across the constant current source can directly reflect corresponding voltage protection values when different numbers of battery packs are connected in series; the processing circuit is connected across the constant current source, and uses the voltage across the constant current source as a voltage protection value to compare same with a voltage after the plurality of battery packs are connected in series. According to the battery system provided by the present application, the voltage protection value is directly represented by means of the voltage across the constant current source, and there is no need for an installation worker to open a switch box on site to adjust the voltage protection value by means of a DIP switch, thereby achieving convenience and rapidness, improving the safety, and reducing personnel costs.
