Battery residual capacity output time assessment device and electric vehicle

Abstract

The invention discloses a battery residual capacity output time assessment device and an electric vehicle. The battery residual capacity output time assessment device comprises an electric quantity detection module, a control assembly, a temperature detection module, a discharge rate detection module and a storage module, and is used for calculating effective and continuous output time of a battery under the conditions of different residual electric quantities, different temperature and different discharge rates. The electric vehicle adopts the battery residual capacity output time assessment device above; the distance between the electric vehicle and the destination as well as expected driving distance of the electric vehicle can be calculated through a GIS system; and when the electric quantity of the electric vehicle cannot meet the electric quantity demand of the distance above, an alarm signal is sent to prevent the case that the battery runs out in the electric vehicle driving process.

Description

technical field [0001] The invention relates to the field of electric vehicle and battery management technology, more specifically, it relates to a battery remaining power output time evaluation device and an electric vehicle. Background technique [0002] With the enhancement of people's awareness of environmental protection, new energy vehicles are more and more popular. Among them, electric vehicles have attracted a large number of consumers with their convenient and green concept. [0003] However, electric vehicles still have some disadvantages compared with fossil energy vehicles, such as battery life. When the driver drives the above-mentioned electric car to a distant destination, he cannot clearly know whether he can reach the destination with the power of the battery, which may cause the driver to run out of power in the electric car while driving. Bring a lot of inconvenience to the driver. [0004] In order to make it easier for the driver to understand the re...
