Abstract

The invention discloses a method for protecting the vehicle battery with the function of analyzing power noise signal mode and the device thereof. The device comprises: a power characteristics sensingdevice for detecting the voltages of vehicle main battery and standby battery, and detecting the current value and power noise signal; a power characteristic analysis method: analyzing the spectrum mode of the power voltage, current and noise signal by employing the power characteristics, and further judging vehicle operation status and power status; a power manage and control unit, adjusting timeinterval via variable timing circuit, and switching or cutting main battery or standby battery according to the vehicle operation and power status. The invention can prevent power exhaustion after th e engine motor stopping.

Description

technical field [0001] The invention relates to a method and device for protecting a vehicle battery, in particular to a method for managing power consumption status and battery power with the function of analyzing the noise signal mode of the vehicle battery power supply, and is implemented through a physical circuit. The invention is applied to the safety management of a vehicle battery with an engine activation device and a charging device. Background technique [0002] The reliability of various systems of modern vehicles is generally valued. Generally speaking, the supply of vehicle power focuses on correctness and safety. Providing stable, appropriate and convenient power for vehicles and personnel is one of the important goals of the power supply system. . However, the power consumption of vehicles is becoming more and more complicated. When the vehicle stops and the power switch is turned off, the battery still needs to supply power to laptops, reading lights, stere...
