Abstract

The invention discloses a battery information sensing system which comprises a temperature and humidity sensor module, a battery management module, a battery sensing module and an interface module, wherein the temperature and humidity sensor module is connected with the battery sensing module; the battery management module is connected with the battery sensing module; the battery sensing module is connected with the interface module; the temperature and humidity sensor module is used for acquiring the external temperature and humidity information of the battery; the battery management module is used for acquiring the internal information of the battery; the interface module comprises a plurality of interface sub-modules and is used for transmitting the data transmitted by the battery sensing module to the peripheral equipment through the plurality of interface sub-modules; the battery sensing module is used for processing the external temperature and humidity information of the battery which is acquired by the temperature and humidity sensor module and the internal battery information which is acquired by the battery management module, acquiring the current operating state of the battery, selecting different transmission paths according to the current operating state of the battery and transmitting the processed information to the peripheral equipment through different interface sub-modules in the interface module.

Description

technical field [0001] The invention relates to the technical field of battery perception, in particular to a system and method for electric vehicle battery information perception. Background technique [0002] As a new type of means of transportation, electric vehicles have been widely used due to their advantages such as no pollution, low noise, and high energy efficiency. Electric vehicles use batteries as energy sources, generally using lithium iron phosphate batteries. Because the battery is generally used in a closed environment, there is a certain hidden danger of spontaneous combustion or explosion. Therefore, there is an urgent need for a method to collect and monitor the battery's own state and peripheral environment information to prevent possible safety problems. [0003] In the prior art, there is a battery management system (Battery Management System, BMS), which can accurately estimate the state of charge (State of Charge, SOC) of the power battery pack, tha...

Problems solved by technology

However, this method can only monitor the state of charge of the battery, and cannot provide the user with information about the surrounding environment of the battery.

On the other hand, due to the difference in the current working state of the battery, such as the battery being on the shelf (charging state), in use, or in the library (unused state), the battery information that different terminals want to obtain is also different. The existing technology provides The method cannot distinguish the monitored information according to the working status of the battery, so that it can be transmitted to the handheld terminal or the master station management system accurately and in time, and cannot enable the user or the battery manager to obtain the required battery status information
