Destination remaining endurance mileage calculation method and device

Abstract

The invention discloses a destination remaining endurance mileage calculation method and device, and the method comprises the steps: receiving an actual distance from a current position of an electricvehicle to a destination and a mileage correction coefficient sent by a cloud server, and the current remaining endurance mileage of the electric vehicle, and calculating the destination remaining endurance mileage, wherein the mileage correction coefficient is the ratio of the total estimated power consumption corresponding to the actual distance to the power consumption of the electric vehicleunder the standard working condition, and the total estimated power consumption is the sum of the estimated running power consumption corresponding to the actual distance and the estimated air conditioner power consumption; the problems that according to an existing remaining endurance mileage calculation method, the difference between actual driving working condition energy consumption and standard energy consumption is not considered, and the electric quantity consumed by an air conditioner is not considered, so that deviation exists between the calculated remaining endurance mileage and theactual endurance mileage; and the technical problems of insufficient electric quantity and half-way anchoring in the planned travel are easily caused.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a method and device for calculating the remaining cruising range of a destination. Background technique [0002] The remaining cruising range of the destination refers to the remaining mileage of the electric vehicle after the electric vehicle arrives at the destination through calculation under the current state of the electric vehicle. Most of the existing electric vehicles are calculated based on the state of charge (SOC) of the power battery to display the remaining range of the vehicle. For example, the maximum range of 500km multiplied by the battery SOC (such as 50%), it can be obtained that the remaining battery life is 500km*50%=250km. However, the actual driving conditions (high-speed, suburban, urban, etc.) are different from the NEDC standard conditions. The actual driving range of 40km may drop by 30km or 50km, and most electric vehicles have a d...

Problems solved by technology

[0003] This application provides a method and device for calculating the remaining cruising range of the destination, which is used to solve the problem that the existing calculation method of the remaining cruising range does not consider the difference between the energy consumption of the actual driving condition and the standard energy consumption, and does not consider the consumption of the air conditioner. Power, so that there is a discrepancy between the calculated remaining cruising range and the actual cruising range, which may easily lead to technical problems such as insufficient power and a breakdown in the planned itinerary
