Abstract: Systems, devices and methods relating to the charging of electrical energy storage devices on passenger buses. A passenger bus (30) comprises an electrical energy storage device (34) for supplying electrical power to an electrical load (36); an interface (40) for receiving electrical power from an off-board source (42); and an on-board charger (38) electrically coupled to the electrical energy storage device (34). The on-board charger (38) is configured to convert electrical power received from the off-board source (42) via the interface (40) to a form suitable for charging the energy storage device (34).

Abstract: An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.

Abstract: Systems, methods, devices, and computer programming products useful for the gathering and use of data relating to structural loading and other operational use of transit and other vehicles, and their systems. Systems according to the invention can, for example, comprise one or more data acquisition devices such as strain gauges, accelerometers, or other sensors; data processors; memories; and communications systems. Such systems, methods, and programming are useful in a wide variety of ways, including, for example, monitoring the structural status and use of vehicles and their systems, including fatigue other operational analyses; gathering and applying data useful in the maintenance of such vehicles and the routes they travel; monitoring the use/abuse of such vehicles by operators and other individuals; reporting traffic events or anomalies; and routing transit and other vehicles around such events or anomalies.
