Problems solved by technology

[0004] At present, the sampling and management of multi-level battery systems are mostly centralized local sampling and bus connection. The local sampling system has an external bus connection port, but they do not have the signal transmission function suitable for different levels at the same port, so the serial cascading data transmission between batteries cannot be realized

Abstract

The invention discloses an ad-hoc network battery monitoring micro unit which comprises a digital micro processing module, a power module, a battery signal collection module, a signal receiving module and a signal sending module, wherein the power module, the battery signal collection module, the signal receiving module and the signal sending module are connected with the digital micro processing module; and the battery signal collection module is connected with the power module. According to the micro unit, independent sampling is carried out on each battery in serial connection with a battery pack, signals are gradually downloaded according to changes of voltage of the batteries, and the micro unit achieves data processing and storage for various battery states locally and responds to control and command signals transmitted by a control unit through a data link.

Description

[0001] technical field [0002] The invention relates to the field of battery monitoring, in particular to an ad hoc network battery monitoring micro-unit. Background technique [0003] Parameters such as the voltage and temperature of the battery itself reflect the state of the battery, and are an important basis for changing the charging phase of the battery pack, ending charging, calculating endurance and judging the balance between individual batteries. Therefore, accurate detection, correct use and control of the parameters of each battery is an important means to prolong battery life and ensure safe use. [0004] At present, the sampling and management of multi-stage battery systems are mostly centralized local sampling and bus connection. The local sampling system has an external bus connection port, but they do not have the signal transmission function suitable for different levels at the same port, so cascade data transmission between batteries cannot be realized. ...
