ELECTRIFIED VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240116398 titled 'ELECTRIFIED VEHICLE

Simplified Explanation

An electrified vehicle patent application abstract describes a system that includes a battery, a motor drive device, and a battery controller. The system is designed to optimize battery performance based on regenerative braking ratios and adjust output limiting accordingly.

• The system includes a battery, a motor drive device, and a battery controller.
• The motor drive device is configured to drive a motor through an inverter based on the battery voltage.
• The battery controller determines whether to perform output limiting on the battery based on the regenerative braking ratio.
• The regenerative braking ratio varies according to the battery's charging and discharging levels within a preset time interval.
• The system adjusts the derate ratio associated with a battery output limit value based on the output limiting being performed on the battery.

Original Abstract Submitted

an electrified vehicle includes: a battery; a motor drive device configured to drive a motor through an inverter, based on a voltage of the battery; and a battery controller configured to determine whether to perform output limiting on the battery, based on whether a ratio of regenerative braking is less than or equal to a preset ratio, wherein the ratio of regenerative braking is varied according to an amount of charging of the battery and an amount of discharging of the battery within a preset time interval, and adjust, based on the output limiting being performed on the battery, a derate ratio associated with a battery output limit value.
