Abstract:
A method is provided for balancing the voltage of multiple series-connected electrochemical cells of an electrical storage system of a hybrid electric vehicle. The method includes discharging the electrical storage system by operating at least one large electrical machine of the vehicle at vehicle standstill until the state of charge of the electrical storage system or the cell having the lowest state of charge has reached a predetermined level, and subsequently balancing the voltage of the cells.
Abstract:
Vehicles that are capable of connecting to the AC grid are described that comprise a prime mover and at least one motor generator. In one embodiment, a vehicle may be constructed as a plug-in hybrid system and using the powertrain under controller instruction to either place power on an AC power line (to service AC grids) or to draw power from the AC power line to add electrical energy to the batteries on the vehicle. In some aspects, vehicles may test whether the power needed to service the AC power line may be satisfied by the on-vehicle batteries or, if not, whether and how much power to extract from the prime mover. In some aspects, vehicles may have a thermal management system on board to dynamically supply desired heat dissipation for the powertrain, if the powertrain is using the prime mover to supply power to the AC grid.

Abstract:
A modular electric power supply adapter device for electric golf cars and electric utility vehicles is advantageous to the existing power supply adapter device for electric golf cars and electric utility vehicles because it is more convenient and more affordable.The problem that exists is that each brand of electric golf car or electric utility vehicle has its own uniquely shaped port. Prior to the present invention, the user needed multiple independent devices. The present invention benefits the user because one modular DC converter assembly now can be detachably coupled to a variety of modular base housing assemblies. The modular base housing assemblies have a variety of shapes to fit the uniquely shaped ports in each brand of electric golf car or electric utility vehicle.A modular electric power supply adapter device plugs into a charging receptacle or IQ port of an electric golf car or electric utility vehicle, and is used to power an electronic apparatus. The main components consist of input electric connectors positioned in a modular base housing assembly adapted to fit a charging receptacle or IQ port of an electric golf car or electric utility vehicle, output and input transfer electric connectors, a DC converter module, and an electrical output fitting adapted to receive an electrical connection such as, but not limited to, a USB, to transmit the DC output power from the DC converter module to the electronic apparatus. The modular DC converter assembly detachably couples to a modular base housing assembly.
Abstract:
An electrical socket cap includes a tether between the cap and an electrical socket, wherein the tether provides power to the cap. The cap is adapted to close an opening to the electrical socket in a closed position, and further adapted to allow access to the electrical socket in an open position. The cap further includes inner and outer surface which include one or more electrical ports disposed thereon. Electrical ports disposed on the inner surface are not accessible when the cap is in the closed position, while ports disposed on the outer surface of the cap are accessible when the cap is in the closed position. Electrical ports disposed on the inner surface are accessible when the cap is in the open position while the electrical socket is also accessible. The tether is electronically coupled to the electrical socket.

Charging service vehicles with battery and generator sources are disclosed. The service vehicle is a vehicle having electric vehicle (EV) charging equipment, removably mounted battery module(s) or a battery module connection point, and an alternator or generator transported by the vehicle. The alternator or generator is configured to provide power to the battery module or to the charging equipment. Battery modules used may be quick-disconnecting or have their discharge monitored and controlled by an onboard controller device, and in some cases are automotive SLI batteries. Some embodiments have connection points that can be configured as charging points to recharge battery modules on the vehicle or as discharging points to provide power to the EV charging equipment. These features are beneficial to extend the utility of batteries in a service vehicle, provide additional power for EV charging, and to efficiently utilize vehicle electronics and generation capability.

A power control system and method for vehicle power outlets is provided which integrally controls power of power outlets mounted in a vehicle to improve the efficiency of power distribution in the vehicle and enable ordinary use of the power outlets while the vehicle is turned off. To this end, the power control system includes a startup power source configured to supply power to a plurality of power outlets mounted in a vehicle while the vehicle is turned on, a battery power source configured to supply power to the power outlet while the vehicle is turned off, and a controller configured to detect whether the vehicle is turned on, a battery charge capacity, and an electric current consumption quantity of each of the plurality of power outlets and determine a type of power that should be supplied to each power outlet and whether to supply power to each power outlet.
Abstract:
Charging service vehicles and methods using modular batteries are disclosed. The service vehicles are vehicles having electric vehicle (EV) charging equipment, and removably mounted battery modules or battery module connection points. The battery modules are connected to the EV charging equipment as a source of electrical energy. Some embodiments disclose integrating the EV charging equipment with the vehicle, recharging modules through a distribution grid connection, the manner of discharging the batteries, modes of connecting and disconnecting the modules, the size and weight of the modules, quick-disconnectability of modules, control and monitoring of the modules and charging equipment, and/or ways of connecting modules to the vehicle. These features are beneficial to efficiently keep service vehicles available for EV charging through exchanging battery modules or providing additional battery modules when necessary, and may keep operators safe through de-energization of connectors and other precautions inherent in these designs.
