Embodiments include a battery pack having a balanced current collector plate configured to connect a plurality of battery cells to one another and an electric vehicle including the same. The balanced current collector plate includes a terminal and a plurality of cell connection regions, each corresponding to one of the plurality of battery cells. Each of the plurality of cell connection regions includes one or more sidewalls, a cell connection tab that is configured to contact a terminal of a battery cell, and a cell fuse that is configured to electrically connect the cell connection tab to the balanced current collector plate. The geometry of each of the plurality of cell connection regions is configured to minimize a difference among the current draw between each of the plurality of battery cells and the terminal.

A system in a vehicle includes two or more smart battery packs to power drive units of the vehicle to move the vehicle. Each of the two or more smart battery packs includes a battery pack, and a battery management system (BMS) to monitor a state of charge of the battery pack. An energy distribution unit facilitates charge transfer among the two or more smart battery packs.

A switchable powertrain comprises at least four points of freedom. The switchable powertrain comprises a main gear set configured for gear ratio selection, the main gear set comprising main gears coupled to a main shaft and second gears coupled to a second shaft. An adapter comprises a first selective coupling configured to selectively couple to the main shaft, and a second selective coupling configured to selectively couple to the second shaft. A first torque source and a clutch are configured for selectively coupling or decoupling first torque to the main shaft. A second torque source is configured for selectively outputting second torque to the first selective coupling or to the second selective coupling.

An electric vehicle charging device includes a processing unit having a memory with a routine stored therein which, when executed by the processing unit causes the processing unit to control circuitry to prevent the electric vehicle charging device from charging an electric vehicle for a random delay period and to allow the electric vehicle charging device to charge the electric vehicle starting when the random delay period ends, wherein the random delay period starts at a predetermined start time and lasts a random delay length of time. The random delay reduces the peak load on a transformer that the electric vehicle charging device and other electric vehicle charging devices receive power from.

A method of operating an electrical feeder permits the electrical feeder voltage to be maintained at the minimum voltage within a voltage range based upon dynamic grouping together of electrical generators on the electrical feeder with demand response loads on the electrical feeder. A method of assessing the proper operation of a voltage control device on the electrical feeder involves detecting a number of properties of the electrical power in the electrical feeder both prior to and subsequent to a change in an operational parameter of a voltage control device. An expected effect upon the electrical feeder of one or more distributed generators is filtered from this in order to determine a net effect of the voltage control device itself on the electrical feeder. Based upon the detected net effect and a predicted baseline effect for the voltage control device, it can be determined whether the voltage control device is functioning properly.
