Device and method for monitoring and reminding vehicle-mounted battery power

Abstract

The invention provides a vehicle battery power monitoring and reminding device, comprising a vehicle battery, a coulomb counter connected in series with the vehicle battery, an MCU module connected in parallel with the vehicle battery, and a signal transceiver module connected to the MCU module signal, the MCU module stores The initial charge S of the vehicle battery 0 , and record the working hours of the vehicle battery t n , the coulomb counter is used to obtain and transmit the circuit current In flowing through the coulomb counter, and the MCU module can use the obtained circuit current In and the initial power S of the vehicle battery when the vehicle is turned off 0 , working hours tn Obtain the remaining working hours Tn and the remaining power Sn of the vehicle battery, the signal transceiver module is used for regular or when the remaining power Sn of the vehicle battery is less than or equal to the minimum remaining power Smin, or when the remaining working time Tn of the vehicle battery When it is less than or equal to the minimum remaining working time Tmin of the vehicle battery, the power information of the vehicle battery is sent to a mobile terminal. The invention also provides a vehicle battery power monitoring and reminding method.

Description

technical field [0001] The invention relates to the technical field of battery power monitoring, in particular to a vehicle battery power monitoring and reminding device and method. Background technique [0002] Although the current car itself will have a battery fault light, this fault light will roughly show whether the state of the battery is good or bad only after the car is started, that is, when it is not turned off; There is no storage capacity monitoring device when the vehicle is in the flameout state, so that the driver cannot know the state of the power of the vehicle's own storage battery. [0003] Therefore, after the car is parked and turned off in many cases, the driver sometimes does not leave the vehicle immediately. At this time, sometimes the driver will also turn on the air conditioner, or turn on the CD player, or turn on the navigation, or turn on the radio, etc., but the driver's These operations will consume the power of the vehicle battery, which wi...

[0002] Although the current car itself will have a battery fault light, this fault light will roughly show whether the state of the battery is good or bad only after the car is started, that is, when it is not turned off; There is no storage capacity monitoring device when the vehicle is turned off, so that the driver cannot know the state of the vehicle's own battery power

[0003] Therefore, after the car is parked and turned off in many cases, the driver sometimes does not leave the vehicle immediately. At this time, sometimes the driver will also turn on the air conditioner, or turn on the CD player, or turn on the navigation, or turn on the radio, etc., but the driver's These operations will consume the power of the vehicle battery, which will easily cause the vehicle to fail to start; or after the vehicle is stopped and the engine is turned off, the driver leaves the vehicle, and at this time, because the electronic equipment such as the DVR on the vehicle is still in the background standby or working state, it will also consume the power of the battery, and if the vehicle is parked for a long time, it may also cause the vehicle to fail to start, and after the owner (driver) arrives at the scene, he will not be able to judge the current situation immediately. The reason why the vehicle cannot be started will bring additional vehicle maintenance costs to the owner
