Patent number: 10035428Abstract: A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.Type: GrantFiled: April 27, 2016Date of Patent: July 31, 2018Assignee: Gogoro Inc.Inventor: Yi-Tsung Wu

Patent number: 9906035Abstract: A method of operating an electrical feeder permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.Type: GrantFiled: March 3, 2016Date of Patent: February 27, 2018Assignee: COOPER TECHNOLOGIES COMPANYInventors: Dongbo Zhao, Yigang Wang, Chinmaya Baburao Patil
