BATTERY MANAGEMENT SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18216243 titled 'BATTERY MANAGEMENT SYSTEM
Simplified Explanation
The battery management system described in the patent application involves a vehicle and a center. The vehicle has an acquisition unit for collecting vehicle data and a transmission unit for sending this data to the center. The center, in turn, includes a reception unit for receiving the vehicle data and a determination unit for assessing the battery's state based on this information. Specifically, when the vehicle is not parked, the determination unit identifies a temporary overdischarge state of the battery if the battery voltage upon starting the vehicle is below a certain threshold and the total charge and discharge amount is within a specific range.
- The system consists of a vehicle with data acquisition and transmission units, as well as a center with reception and determination units.
- The determination unit in the center assesses the battery's state based on the vehicle data received.
- A temporary overdischarge state of the battery is identified when specific conditions related to voltage and charge/discharge amount are met.

Original Abstract Submitted
The battery management system includes a vehicle and a center. The vehicle includes an acquisition unit that acquires vehicle data, and a transmission unit that transmits the vehicle data to the center. The center includes a reception unit that receives vehicle data from the vehicle, and a determination unit that determines a state of the battery based on the vehicle data. When the vehicle is not parked, the determination unit determines that the battery is in a temporary overdischarge state, when the voltage of the battery when the vehicle is started is less than a first voltage and the integrated value of the charge and discharge amount of the battery is in a first state in which the integrated value of the charge and discharge amount of the battery is less than a first charge and discharge amount.
