Publication number: 20230141525Abstract: A battery manager includes a pattern estimator, a prediction engine, and a charging scheduler. The pattern estimator estimates a driving pattern of an electric vehicle. The prediction engine predicts a charging parameter based on at least one of the driving pattern or driver charging behavior. The charging scheduler outputs the charging parameter to control charging of a secondary battery of the electric vehicle. The pattern estimator may estimate the driving pattern based on information from at least one information source of the electric vehicle. The prediction engine predicts the charging parameter of the secondary battery in preparation of a future use of the electric vehicle.Type: ApplicationFiled: November 5, 2021Publication date: May 11, 2023Applicant: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Arlo C. Eitzer, Lisa B. DiMaggio, Allison McGowan, Emily S. Lerner, Alessandro Concas, Abril A. Galang, Jordan Choby, Max K. Ralya, Tapan V. Patel, Benjamin J. Groelke

Patent number: 10793013Abstract: A vehicle charging system includes an on-board charger for receiving electrical power from an EVSE. The system includes a memory for storing routine charging location data and a plurality of timer functions. The system includes a sensor for detecting data. The system further includes an ECU for determining whether the on-board charger is located at a routine charging location. The ECU controls the on-board charger to receive the electrical power when the on-board charger is located at a routine charging location and a current time of day is within the time of day defined by the timer function and controls the on-board charger to receive the electrical power when the on-board charger is located at a non-routine charging location regardless of the current time of day. The system includes an output device designed to output data indicating that the on-board charger is receiving the electrical power from the EVSE.Type: GrantFiled: January 27, 2017Date of Patent: October 6, 2020Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventor: Tapan V.

Patent number: 10640004Abstract: A system includes an on-board charger that receives energy from an external power source and a battery having a state of charge (SOC) and a battery temperature. The system also includes a battery heater that converts electrical energy into thermal energy (heat) for increasing the battery temperature. The system also includes a battery management system (BMS) that determines or detects a current SOC of the battery and a current battery temperature. The system also includes an electronic control unit (ECU) coupled to the on-board charger and to the BMS. The ECU controls the on-board charger to distribute energy to the battery and to the battery heater to cause the SOC to remain above a SOC threshold and to cause the battery temperature to remain above a battery temperature threshold based on the current SOC and the current battery temperature.Type: GrantFiled: January 29, 2016Date of Patent: May 5, 2020Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventor: Tapan V.
