Battery, battery management system, mobile platform and electric device

Abstract

A battery management system is used for managing the voltage output of a battery and includes a communication interface which is used for communicating with a power supply controller of a mobile platform, and the communication interface is used for obtaining the electrical parameters of the battery where the communication interface is located and transmitting the electrical parameters to the powersupply controller of the mobile platform, so that the power supply controller generates the corresponding different types of voltage output control signals according to the electrical parameters. Thecommunication interface also receives different types of voltage output control signals sent by the power supply controller, and a battery controller is connected with the communication interface andis used for determining the type of the voltage to be outputted of the battery according to the type of the voltage output control signal received by the communication interface and generating a corresponding voltage output instruction according to the type of the voltage, so that the battery is controlled to output the corresponding voltage. The invention also relates to the battery, the mobileplatform and an electric device.

Description

[0001] This application is a divisional application with the application number 201680004470.2, the application date is November 14, 2016, and the invention name is battery, battery management system, mobile platform and electrical equipment. technical field [0002] 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 [0003] 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: [0004] 1. When batteries of different voltages are used in...

AI Technical Summary

Problems solved by technology

[0004] 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;

[0005] 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;

[0006] 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;
