Patent number: 10625615Abstract: Vehicle battery management systems (BMS) and methods are described, in which the output of a vehicle battery is reduced by activating a shutdown mode. A BMS may be configured to start a timer when the vehicle is turned off, e.g. based on when the main power between the vehicle and the battery is interrupted or based on a signal from the vehicle control system. The BMS may further be configured to store BMS data (e.g. variable data related to operation and/or status of the battery) to an electronic storage device, and to switch the battery to a shutdown mode, when the timer reaches a predetermined value. The BMS may be further configured to load the BMS data from the electronic storage device and/or to deactivate the shutdown mode when the vehicle is turned back on.Type: GrantFiled: March 7, 2018Date of Patent: April 21, 2020Assignee: Thunder Power New Energy Vehicle Development Company LimitedInventor: Ming-Chieh Cheng

Patent number: 10525787Abstract: Electric vehicle thermal management systems and electric vehicles using the thermal management system, are disclosed. A passenger cabin is heated by the heat dissipated from a battery and/or a motor. A cooling circuit in the management system fluidly connects the battery, the motor and a first radiator in series. The first radiator provides a heat source to the passenger cabin by means of the heat dissipated from the battery and/or the electric motor. Under certain conditions, the electric motor is selectively separated from the cooling circuit, so that when the passenger cabin needs to be heated, the thermal management system can provide heat to the passenger cabin without affecting the heat dissipation of the battery.Type: GrantFiled: October 4, 2017Date of Patent: January 7, 2020Assignee: Thunder Power New Energy Vehicle Development Company LimitedInventor: Ming-Chieh Cheng
