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.
