Automobile power supply management method

Abstract

The invention discloses an automobile power supply management method, which comprises the following steps: detecting the residual electric quantity and the electric quantity detection deviation of a low-voltage storage battery, the electric quantity detection deviation representing the deviation state of the residual electric quantity detection result under the current working environment; the residual electric quantity and the electric quantity detection deviation of the low-voltage storage battery are sent to a controller; the controller opens or closes the power management module according to the residual electric quantity of the low-voltage storage battery and the electric quantity detection deviation. According to the automobile power supply management method provided by the invention, the residual electric quantity and the electric quantity detection deviation of the storage battery are detected, and according to different detection results, the discharge energy of the storage battery in a low-electric-quantity state is reduced through energy reminding, load reduction or load turn-off limitation, so that the storage battery is ensured to have sufficient electric quantity for starting the automobile; the electric quantity state of the vehicle can be remotely monitored in real time; when the vehicle is in a static state, the whole vehicle power supply is subjected to hierarchical management, and the vehicle power supply condition is remotely monitored.

Description

technical field [0001] The invention relates to the technical field of vehicle power management, in particular to a vehicle power management method. Background technique [0002] In the non-standard use of vehicle electrical appliances when the vehicle is stationary and not running, the user must manage the power supply to avoid causing the battery to lose power and affect the normal start of the vehicle. If there is an abnormality in the power supply of the vehicle, it is necessary to remind the user to facilitate the user to detect and deal with it as soon as possible. Finally, if the user does not use the vehicle for a long time, if there is a risk of power loss of the vehicle power supply, the user can be reminded to deal with it as soon as possible through the mobile phone APP text message. Vehicle power management includes battery power management, in-vehicle power reminder, and remote terminal power reminder. [0003] The current vehicle power management strategy on...

Problems solved by technology

The disadvantage of this management strategy is that, on the one hand, when the vehicle is stationary and not started, it does not manage the power supply of the whole vehicle, nor does it remind the user, so that it is easy to find and deal with problems early

On the other hand, when the vehicle has not been powered for a long time and the battery is low and the engine starts, it does not actively remind the user of the vehicle status in time, resulting in the user's model being unable to start and use normally.
