Vehicle battery electric quantity monitoring and reminding device and method

Abstract

The invention provides a vehicle battery electric quantity monitoring and reminding device, including a vehicle batteries, a coulometer connected in series with the vehicle battery, an MCU module connected in parallel with the vehicle battery and a signal transceiver module connected in signal with the MCU module. The MCU module stores the initial power S0 of the vehicle battery, and the working time tn of the vehicle battery is recorded. The coulometer is used for acquiring and delivering circuit current In flowing through the coulometer. The MCU module is capable of obtaining remaining working time Tn and residual electric quantity Sn according to the obtained circuit current In, the initial electric quantity of the vehicle battery S0 and the working time tn. The signal transceiver module is configured to transmit electric quantity information of the vehicle battery to a mobile terminal periodically or when the remaining electric quantity Sn of the vehicle battery is less than or equal to the minimum remaining electric quantity Smin or when the remaining working time Tn of the vehicle battery is less than or equal to the minimum remaining working time Tmin of the vehicle- battery. The invention also provides a vehicle battery electric quantity 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
