Abstract

A battery management system (212) for managing the voltage output of the contained battery. The battery management system (212) includes a communication interface (2122) and a battery controller (2127). The communication interface (2122) is used to communicate with a power controller of a mobile platform, and the communication interface (2122) acquires the electrical parameters of the battery and transmits the electrical parameters to the power controller of the mobile platform , for the power supply controller to generate corresponding voltage output control signals according to the electrical parameters. The communication interface (2122) also receives the voltage output control signal sent by the power controller. The battery controller (2127) is connected to the communication interface (2122), and is used to generate a corresponding voltage output instruction according to the voltage output control signal received by the communication interface (2122), so as to control the corresponding output of the battery. voltage. The invention also relates to a battery, a mobile platform and an electric device.

Description

technical field [0001] The invention relates to the technical field of safety management of an intelligent battery combined power supply system, in particular to a battery, a battery management system, a mobile platform and electrical equipment. Background technique [0002] As the power of electrical equipment increases, it is usually necessary to connect lithium batteries in series and parallel to form a more complex power supply system. In a multi-battery combination power supply system, the voltage and power of each battery may be different, and the combination of batteries with different power and voltage usually introduces some safety and compatibility issues, such as: [0003] 1. When batteries of different voltages are used in parallel, there is often a battery with a higher voltage charging a battery with a lower voltage with a large current, causing potential safety hazards and damage to the battery cell; [0004] 2. Each battery has an independent switch button a...

AI Technical Summary

Problems solved by technology

[0003] 1. When batteries of different voltages are used in parallel, there is often a battery with a higher voltage charging a battery with a lower voltage with a large current, causing potential safety hazards and damage to the battery cell;

[0004] 2. Each battery has an independent switch button and power indicator. When each battery is turned on first and then combined into the power supply system, there will often be a large current impact at the moment of connection, which will cause circuit damage;

[0005] 3. The combined power supply system needs a general switch button to turn on, plus the signal line and power supply line, which will lead to more interface terminals;
