Battery management system and method based on Internet of Things for power battery

Abstract

The invention provides an external battery management extension system based on the Internet of Things, an improved battery management system and a corresponding interaction method, and the system comprises a data communication interface used for the data communication with a cloud server through a network; a memory used for storing special terminal software of a power battery Internet of Things management system; a processor used for executing special software for the power battery Internet of Things management system terminal so as to manage a power battery pack, wherein the power battery Internet of Things management system terminal special software interacts with the cloud server through the data communication interface and receives data returned from the cloud server so as to performmanagement, configuration, updating, upgrading or fault detection on the battery management system.

Description

Technical field[0001]The present disclosure relates to a battery management system for batteries, in particular to a battery management system for power batteries based on the Internet of Things.Background technique[0002]With the continuous development of new energy technologies, more and more vehicles that use traditional energy as power are beginning to use rechargeable batteries as their power core in response to the requirements of green travel. For example, vehicles such as scooters, bicycles, tricycles, mopeds, motorcycles, automobiles, and boats have begun to use power batteries (energy storage batteries) as their driving power. For a power battery, in addition to a battery pack composed of one or more battery boards, a special battery management system (Battery Management System, BMS) is also needed to manage the battery pack. BMS is a system for battery management. It usually has the function of measuring battery voltage to prevent or avoid battery over-discharge, over-char...

AI Technical Summary

Problems solved by technology

This mechanism of bundling the battery management system with the battery pack has great limitations, for example, it cannot work adaptively according to different battery types, so that the battery management system needs to be designed separately for each type of battery, Therefore, it will bring a high technical threshold and a huge development cycle and cost to the power battery application

At the same time, the built-in form is not conducive to upgrading the battery pack, such as management system upgrades, capacity expansion, Internet of Things access, etc., and is also not conducive to the recycling and reuse of the battery management system

[0004] And, more importantly, the existing battery management system only stays at the stage of providing battery health status data

It cannot effectively use the collected battery information, for example, it cannot provide possible fault causes and solutions by analyzing the data

Therefore, there are great limitations
