ELECTRIFIED VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18195106 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 battery controller determines whether to perform output limiting on the battery based on the ratio of regenerative braking and adjusts a derate ratio associated with a battery output limit value.

• 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 ratio of regenerative braking.
• The ratio of regenerative braking varies according to the charging and discharging of the battery within a preset time interval.
• The battery controller adjusts a 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.
