Abstract: A through-the-road (TTR) hybridization strategy is proposed to facilitate introducing hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

Abstract: An object is to provide a power supply system for a vehicle and a control method for the power supply system that make it possible to securely start the vehicle even in a state where there is a higher possibility that a user does not perform maintenance on the vehicle. A power supply system includes a charging controller, in which, when a soak time representing a period of time elapsed after an off operation has been received is shorter than a first period of time that is determined beforehand, a coupling state detector has detected that there is coupling between an external power supply and an on-vehicle charger, and a remaining amount in a low voltage battery is equal to or below a predetermined remaining amount, the charging controller causes the low voltage battery to be charged with electricity.
