New energy automobile management method and system

Abstract

The invention belongs to the field of new energy automobiles and aims to provide a new energy automobile management method capable of finely managing the battery of a new energy automobile. The method comprises the following steps of: S1, unit voltage measurement for measuring the voltage of each unit battery; S2, unit temperature measurement for measuring the temperature of each unit battery; S3, battery information feedback for feeding back the voltage and the temperature of each unit battery to an onboard ECU and enabling the onboard ECU to generate a chart to provide information for a driver via a display module; S4: multi-platform checking for enabling the onboard ECU to send the voltage and temperature information of each unit battery to a cloud service platform via a wireless module, and enabling the cloud service platform to send the chart information to a mobile terminal and a computer terminal. Also disclosed is a new energy automobile management system.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a management method and system for new energy vehicles. Background technique [0002] With the advancement of technology, the energy sources of vehicles are becoming more and more diverse, and now new energy vehicles such as hybrid vehicles and pure electric vehicles have appeared. People are concerned about the endurance of electric vehicles first, the safety of batteries, and the ease of maintenance. [0003] In terms of battery life, because the battery capacity purchased by major manufacturers is roughly the same at the same cost, it does not constitute the main consideration for people. [0004] In terms of battery safety, it is mainly because the battery will generate heat during work (cause of internal resistance, some are also called battery internal resistance), because the battery of an electric vehicle is a battery pack composed of multiple unit cells, each The hea...

Problems solved by technology

[0003] In terms of battery life, because the battery capacity purchased by major manufacturers is roughly the same at the same cost, it does not constitute the main consideration for people.

[0004] In terms of battery safety, it is mainly because the battery will generate heat during work (cause of internal resistance, some are also called battery internal resistance), because the battery of an electric vehicle is a battery pack composed of multiple unit cells, each The heat dissipation capacity of each unit battery is inconsistent. If reasonable monitoring and heat dissipation are not carried out, the heat in the battery pack will accumulate and cause damage to the unit batteries, reducing the battery charge and discharge cycle efficiency. In severe cases, it will also cause thermal runaway and affect driving safety.

The existing battery management system mainly evaluates the battery pack as a whole, and the monitoring of the unit cells is not enough
