Problems solved by technology

However, most of the traditional power batteries lack intelligent charging and discharging control strategies, and most of them are charged with a fixed current and the internal resistance characteristics of the battery itself. This method often makes the battery need a longer charging time. At some point, the charging current of the battery will exceed the maximum current value it can withstand, which will cause serious heating of the battery, and will have an irreversible impact on the life and capacity of the battery in the long run

Abstract

The invention relates to a battery charging management system applied to an electric vehicle. The battery charging management system comprises a front-end battery parameter sampling module, a data transmission module, a central control module and a lower-end command execution module, wherein the front-end battery parameter sampling module is used for collecting power battery working parameter data; the data transmission module is used for transmitting the power battery working parameter data collected by the front-end battery parameter sampling module to the central control module; the centralcontrol module is used for analyzing the data to obtain a current battery state and analyzing and calculating the state of charge and required charging current of a battery, thereby controlling the lower-end command execution module; and a mixed algorithm of an Ampere-Hour integral method and an open circuit voltage method is adopted by a method, for calculating the state of charge (SOC) of the battery, for the central control module. Related faults of the battery in the working process are diagnosed through monitoring related working parameters, such as voltage, current and temperature in real time, thereby ensuring efficient, safe and reliable working of the battery.

Description

technical field [0001] The invention relates to the field of new energy vehicle power systems, and is a battery management system suitable for electric vehicle power batteries in high-voltage and high-current working modes, and specifically relates to a battery charging management system applied to electric vehicles.
