Cold-chain-based electric vehicle charging reminder method, device and mobile terminal

Abstract

The embodiment of the invention provides a cold-chain-based electric vehicle charging reminder method, a device and a mobile terminal. The invention obtains the first position information of the electric vehicle and the second position information of each charging pile within the preset range when the current electric quantity value of the battery of the electric vehicle is detected to be lower than the first preset value. A charging pile and a shortest route length value closest to the electric vehicle are confirmed according to the first position information and the second position information. A first electric quantity value required to complete the driving of the closest route length value is calculated. A time required to finish traveling the shortest route length value is calculated, and a second electric quantity value required to maintain the cargo container of the electric vehicle at a preset temperature is calculated according to the time. When the sum of the first electricquantity value and the second electric quantity value reaches a preset proportion of the current electric quantity value, a prompt message is sent to remind the user to go to the nearest charging pilefor charging so that that charging reminder is realize. Damaging products or breaking down halfway due to insufficient power are avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a cold chain-based electric vehicle charging reminder method, device and mobile terminal. Background technique [0002] With the enhancement of people's awareness of environmental protection, there are more and more battery-driven vehicles, such as electric motorcycles, electric vehicles and so on. However, the endurance of the battery is always inferior to that of gasoline. It often happens that the battery runs out of power during driving and the electric vehicle breaks down. Therefore, it is necessary to go to the charging pile for charging. [0003] Moreover, with the continuous development of cold chain transportation, most fresh products need to be refrigerated and kept fresh during transportation. Therefore, more electricity will be consumed. The product deteriorates because it cannot be cooled effectively. [0004] Therefore, there are defects in the prior art, a...
