Patent number: 11862808Abstract: The vehicle battery pack exchange system herein described charges renters for the time use interval, the energy needed to recharge the battery pack, and the battery wear their use has caused. Data on battery wear accelerating stress parameters such as current, voltage, temperature, and state of charge is collected for battery packs rented to vehicle users. Wear rates are estimated from the collected data. Drivers are displayed information to adapt their driving to battery wear rates. Renters are charged for battery pack usage time, energy supplied by the rental station, and battery wear providing battery owners a secure return on their investment. This system accommodates both short term and sustained long term rentals. Long term rental of one or more battery pack modules for local use gives convenience and low costs while short term rentals of multiple modules provide unlimited range via swapping exhausted packs for recharged units during extended travel.Type: GrantFiled: December 21, 2021Date of Patent: January 2, 2024Inventor: Goodwyn George Reeves

Patent number: 11850954Abstract: An electrified vehicle and associated inverter configured for powering two different types of external loads include first and second phase/line legs combined with a first neutral leg coupled to a vehicle chassis, and a second floating neutral leg that is not coupled to the vehicle chassis. The first/second phase legs and first neutral leg are coupled to a first receptacle configured to receive a corresponding plug to power a first load, such as a power tool or accessory. The first/second phase legs and the second neutral leg are coupled to a second receptacle configured to receive a corresponding plug to power a second load, such as a home or building having an earth grounding electrode. The inverter may include an isolation transformer between the loads and the traction battery, and/or may be configured to provide single phase, split-phase, or three-phase power for either or both of the neutral connections.Type: GrantFiled: February 18, 2022Date of Patent: December 26, 2023Assignee: Ford Global Technologies, LLCInventors: Xi Lu, Krishna Prasad Bhat, Ke Zou, Chingchi Chen, Michael W.

Patent number: 11833920Abstract: A parking aid system aids in alignment parking of a vehicle to a parking space. The vehicle includes: a power receiving unit which receives the electrical power for alignment by way of a power receiving coil; a voltage measuring unit which measures voltage of the power receiving coil; a coil type specifying unit which specifies a type of the power supply coil during the alignment parking; and an alignment aid unit which calculates a target position of the power receiving unit, based on a voltage measured value. The alignment aid unit, in a case of the type of the power supply coil being a DD-type coil, calculates the position of a first peak P1 in the voltage measured value when changing the relative position between the power supply unit and the power receiving unit, and then calculates the target position based on the position of the first peak P1.Type: GrantFiled: March 16, 2021Date of Patent: December 5, 2023Assignee: HONDA MOTOR CO., LTD.Inventor: Naoya Sakakibara
