Automatic coding method for battery thermal runaway detection system

Abstract

The invention discloses an automatic coding method for a battery thermal runaway detection system. Included are an intelligent instrument, a background monitoring center and thermal runaway detectors arranged in a battery box. The thermal runaway detection system is additionally provided with a data concentrator. The data concentrator can carry out communication with and power control over the thermal runaway detectors. Each of the thermal runaway detectors is additionally provided with a coding resistor and an AD code collector. The thermal runaway detectors are provided with a coding function. The two ends of each coding resistor are connected with connecting terminals. The plurality of thermal runaway detectors are connected to a coding control end of the data concentrator by a coding line sequentially through the connecting terminals at both ends of the coding resistors to form a series loop. According to the invention, an ID code can be configured with one key, the operation is simple, the error rate is low, the cost is saved, and mass production and packaging of the product is facilitated.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle battery safety monitoring, in particular to an automatic coding method for a battery thermal runaway detection system. Background technique [0002] A patent document published by the applicant before is CN106066457A, which discloses a battery thermal runaway detection system used in the field of new energy vehicle battery safety monitoring technology, and the thermal runaway detectors of the system are installed separately in each battery box Among them, the device ID needs to be set before leaving the factory. However, in the actual installation process, many installations are not installed according to the pre-set installation number (that is, the device ID), which leads to the occurrence of wrong alarm signal display, which affects later maintenance. . [0003] In order to prevent the occurrence of the above situation, the measures taken in the prior art are to burn different softw...
