Battery state intelligent monitoring system for new energy vehicle

Abstract

The invention discloses an intelligent battery state monitoring system for a new energy vehicle, which comprises an information acquisition module, a converter, a microprocessor and a touch display screen, and is characterized in that the information acquisition module comprises a temperature acquisition module, a current acquisition module, a voltage acquisition module and an electric quantity acquisition module; the temperature acquisition module comprises a temperature sensor, an alarm unit and a heat dissipation unit, and when the alarm unit gives an alarm, the heat dissipation unit operates, when the battery temperature is high, the alarm unit gives an alarm, the buzzer gives an alarm sound, and the atmosphere lamp flickers, so that a user is reminded that the battery temperature is high, and heat in the battery box is extracted in time; and the battery is rapidly cooled through dry ice, so that the risk of spontaneous combustion of the battery is reduced, the life and property safety of a user can be guaranteed, the voltage, current and electric quantity state of the battery can be fed back in real time, and the user can timely and accurately know the running state of the battery and make a response.

Description

technical field [0001] The invention belongs to the technical field of battery monitoring systems, and more particularly relates to an intelligent monitoring system for battery status of new energy vehicles. Background technique [0002] With the development of new energy vehicles, there are more and more innovations in new energy vehicle batteries. New energy vehicle battery is a new type of vehicle battery that uses new energy technology to reduce "greenhouse gas" emission pollution. The role of the battery is the only power source for the vehicle drive system. In a hybrid vehicle equipped with a traditional engine (or fuel cell) and a battery, the battery can not only play the role of the main power source of the vehicle drive system, but also act as an auxiliary power source. If the cell is balanced, then it will eventually go into a deep state of discharge, causing damage and, ultimately, failure of the battery pack. In order to prevent this from happening, the voltag...

Problems solved by technology

[0003] The new energy vehicle battery monitoring system in the prior art cannot respond quickly and timely when it detects that the temperature of the battery is high. It is safe, and the current battery monitoring system is not convenient for real-time feedback of the voltage, current and power status of the battery. Users cannot timely and accurately understand the operating status of the battery and respond. Therefore, we propose an intelligent monitoring of battery status for new energy vehicles. system
