Battery for electric vehicle

Abstract

The invention relates to a battery for an electric vehicle. The battery comprises a box body, the battery is arranged in the box body; the battery is connected with a battery management circuit boardwith a charging protection function; the battery management circuit board collects the charging and discharging current, voltage and temperature of the whole vehicle, calculates the real capacity through an algorithm, sends data to the instrument through the communication port, displays the corresponding voltage, current, battery percentage, remaining mileage, time, direction and charging and discharging state on the instrument, and the instrument is provided with a Bluetooth module, a GPS and a GPRS module. The battery can display various parameters of the battery charged during charging, various parameters of the battery during discharging and various parameters in the driving process.

Description

technical field [0001] The invention belongs to the field of electric vehicle accessories, and relates to a battery, in particular to a battery for an electric vehicle. Background technique [0002] In traditional electric vehicles, the battery is generally installed at the rear of the seat, or between the upper and lower tubes of the frame, and has no other function except as a power supply. [0003] When the user is riding, he usually knows the remaining battery level and some basic driving information on the instrument installed between the two handlebars. This kind of instrument is usually relatively small, with little display content, and cannot display the charging and discharging status of the battery, the voltage, current, battery percentage, remaining mileage, etc. of the battery. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a battery for electric vehicles. [0005] The techn...
