Embodiment Construction

[0029] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0030] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0031] The invention provides a method for evaluating the working state of an electric vehicle battery, comprising the following steps:

[0032] Provide available power detection module, output detection module, temperature sensor, alarm and controller;

[0033] The available power detection module detects the remaining available power of the battery of the electric vehicle;

[0034] The output detection module detects the output current of the electric vehicle during battery use;

[0035] The temperature sensor detects the ambient temperature of the in-use battery of the electric vehicle while the electric vehicle is runn...

Abstract

The invention discloses a method for evaluating the working state of an electric vehicle battery. The second relational table of usage time detects the remaining available power of the battery in use through the available power detection module, determines the available first time length of the battery in use according to the first relational table, obtains the ambient temperature through the temperature sensor, and obtains the ambient temperature according to the second The relationship table determines the available second duration of the battery in use, then compares the first and second durations, and selects the shorter duration as the available remaining duration of the battery in use; sets the countdown to the available remaining duration, and when the countdown reaches the predetermined time , the control alarms will alarm once respectively. The present invention has exquisite setting, high stability, and is easy to realize, and the extra cost for car owners is low, and is suitable for mass popularization and use.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles and relates to a method for evaluating the working state of batteries of electric vehicles. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Therefore, at present, most of the electric vehicles that are driven and put into use around the world are electric and hybrid vehicles. But as long as power is used as power, rechargeable batteries need to be used as mobile power. The energy storage capacity of the rechargeable battery is limited, so the running time after each charge is limited. Therefore, electric vehicle users are checking the existing energy and power o...
