A kind of matching method and system of automobile battery sensor

Abstract

The invention relates to an automobile battery sensor matching method and system. The method comprises the steps that one or more battery configuration codes and battery configuration parameters corresponding to all battery configuration codes are prestored in a battery sensor, and one battery configuration code is selected to serve as a current battery configuration code; a target battery configuration code is preset in a controller; after the battery sensor is assembled and the controller is powered on, the current battery configuration code is sent to the controller through the battery sensor; after the controller receives the current battery configuration code sent by the battery sensor, whether the current battery configuration code is coincident with the target battery configuration code or not is judged; and if the current battery configuration code is not coincident with the target battery configuration code, according to the target battery configuration code, the current battery configuration code of the battery sensor is reset. By means of the automobile battery sensor matching method and system, the problem that when an existing automobile battery sensor is not matched with a storage battery, detection data are prone to being inaccurate is solved, the automobile electronic intelligence is improved, and the automobile manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile electronic detection, and in particular, to a method and system for matching a battery sensor of an automobile. Background technique [0002] With the application and development of vehicle start-stop technology, it has become very common to use batteries as the power source for vehicle start-up. The battery sensor is installed on the negative terminal of the battery to detect the voltage, current and temperature signals of the battery, and calculates the remaining power (SOC) of the battery based on the internal calculation model according to the collected data information, and feeds this information to the superior. Control units (such as engine control systems, body controllers, etc.) to ensure that there is enough power so that the motor can be automatically shut down and started again. However, different types of batteries have different parameters such as capacity, discharge rate, and ch...
