Auto static power supply intelligent management device and method

Abstract

The invention discloses a static power supply intelligent management device and method for an automobile, which includes a battery sensor, a static power management controller, a vehicle body controller, a vehicle information service terminal and a handheld terminal. The battery sensor is connected to the static power management controller through a vehicle bus. The state of charge of the battery is detected by the battery sensor and transmitted to the static power management controller. The static power management controller is respectively connected to the vehicle information service terminal and the vehicle body controller through the vehicle bus. The vehicle information service terminal communicates with the handheld terminal through the mobile communication network. The communication, static power management controller evaluates the state of the battery based on the state of charge of the battery. The device and method of the invention can realize the power management of the automobile under static state.

Description

technical field [0001] The invention belongs to vehicle body electronic control, in particular to an automobile static power intelligent management device and method. Background technique [0002] In order to reduce the energy consumption of the whole vehicle, improve the working efficiency of the automobile power supply system and the life of parts, there are many kinds of automobile power management devices and control methods used in automobiles, such as: "a power management system" recorded in Chinese patent documents Control method for the system and its body controller" (application number 201010609039.5), "vehicle power management device and method" (application number 200910110149.4) and "a vehicle power management system and its management method" (application number 201010215403. X), these devices are all under the normal operation of the vehicle, by detecting the state of the battery, and controlling the electrical load or the generator according to a certain powe...

[0002] In order to reduce the energy consumption of the whole vehicle, improve the working efficiency of the automobile power supply system and the life of parts, there are many kinds of automobile power management devices and control methods used in automobiles, such as: "a power management system" recorded in Chinese patent documents Control method for the system and its body controller" (application number 201010609039.5), "vehicle power management device and method" (application number 200910110149.4) and "a vehicle power management system and its management method" (application number 201010215403. X), these devices are all under the normal operation of the vehicle, by detecting the state of the battery, and controlling the electrical load or the generator according to a certain power management logic, so as to improve the working efficiency of the power system and protect the components; but not enough The most important thing is that these devices cannot be used for power management under static conditions of the car (ie: the power gear is in the OFF state)

In the actual use of the car, it often happens that the driver leaves the car without turning off the headlights and other electrical loads, which will cause excessive discharge of the battery, affect the normal use of the car, and accelerate the aging of the battery
