A battery cassette is disclosed. The battery cassette may include a frame including one or more hollow tubes. The battery cassette may further include a seal component having one or more hollow tubes aligned with the hollow tubes of the frame. The frame and the seal component may be configured to receive one or more battery cells in the hollow tubes.

Battery cassette

A battery system of an electric vehicle includes a plurality of battery packs. Each battery pack includes a plurality of battery cells enclosed within a housing. A battery management device is electrically connected to each of the battery packs and configured to control an electrical output of the plurality of battery packs.

Battery system

A battery system for an electric vehicle includes a first battery module with a first heater and a second battery module with a second heater. The battery system also includes a control system configured to selectively activate the first or the second heater to dissipate energy from the first or the second battery module.

Battery system of an electric vehicle

An electric vehicle charging system includes a power distributing system configured to receive power from a power control system and selectively direct the power to one of a plurality of power dispensers coupled to the power distribution system.

Charging system for electric vehicles

Vehicle depots or yards adapted to charge multiple electric vehicles include multiple charging electrodes to simultaneously direct power to multiple electric vehicles. The charging electrodes may direct power to the electric vehicles from an utility grid or from a secondary power source.

Depot charging of an electric vehicle fleet

A method of locating an electric vehicle at a charging station having multiple chargers is includes, receiving at multiple fixed transceivers positioned at different locations in the charging station, signals from the electric vehicle as the electric vehicle moves in the charging station, and determining, at a controller, a current location of the electric vehicle in the charging station using the signals received by the multiple fixed transceivers.

Locating an electric vehicle at a charging station

A method for charging an electric vehicle using charge current from a charging source. The charge current is determined based at least on the state of charge of the electric vehicle and a chemistry or type of the battery system.

Electric vehicle charging by adjusting charger current based on battery chemistry

A method of controlling the battery system of an electric vehicle includes detecting a thermal event in a first battery pack of a plurality of battery packs of the battery system, and at least partially powering down the electric vehicle automatically in response to the detected thermal event. The method may also include initiating a thermal rejection scheme in response to the detected thermal event.

Thermal event detection and management system for an electric vehicle

A method of operating an electric vehicle having a battery system with a first battery module and a second battery module includes sending a triggering signal. And, in response to the triggering signal, selectively dissipating energy from the first battery module without dissipating energy from the second battery module.

Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The tissue separating device includes a cam mechanism at the distal portion of the sheath that allows the user of the device to more accurately control the extension and rotation of the cutting blade upon being actuated by the handle.
