Abstract

The invention provides a battery management main system suitable for a new energy automobile and a control method. The battery management main system includes an MCU module, a battery management module, a current detection module, a liquid crystal display module, a whole set of voltage and insulating performance measurement module, a heat management module, a clock module and a memory module; the MCU module reads current data of the current detection module, total voltage and insulation resistance data measured by the whole set of voltage and insulating performance measurement module and terminal voltage of a single battery and temperature data which are sent by an acquisition module through CAN channels, and estimates internal states SOC and SOE of a battery pack, the heat management module is driven to perform heat management on the battery pack, battery state information and alarm information are sent to the liquid crystal display module, and corresponding diagnostic information is stored in the memory module. The beneficial effects of the battery management main system are that the system can realize utilization and protection an automobile battery to the greatest extent, improve efficiency of energy utilization, saves energy and reduces emissions, and guarantees safety of use.

Description

technical field [0001] The invention belongs to the field of battery management systems for new energy vehicles, and in particular relates to a main battery management system suitable for new energy vehicles and a control method thereof. Background technique [0002] The battery management system is an important part of a hybrid vehicle, and a common distributed battery management system consists of an acquisition slave board and a control master system. Among them, the main system plays a core control function in the entire battery management system. The main system reads and collects the voltage and temperature data of each single battery in the battery pack collected by the slave board, and collects the charging and discharging current and total voltage of the battery pack, and analyzes and processes the data of these voltages, currents and temperatures to realize Real-time online estimation of battery pack usage status such as state of charge (StateOfCharge, SOC) and st...
