摘要： A tapered busbar for an energy storage device is provided. The tapered busbar is configured to interconnect with a first row of series-connected energy storage cells in a battery module at a first end of the busbar. As the busbar tapers from a first cross-sectional area at the first end to a larger second cross-sectional area at a second opposite end, the busbar is configured to interconnect with sequentially additional electrically-parallel rows of series-connected energy storage cells. The tapered cross-sectional area of the busbar provides a substantially uniform current density at any point along the length of the busbar regardless of the number of rows of energy storage cells connected before or after the point.

摘要： Systems and methods of detecting leakage and other issues with electrical battery housings are provided. By using an air compressor to alter the air pressure within a battery housing, a processor may detect an abnormal rate of change in the air pressure within the battery housing as compared to a rate of change of an ideal battery housing.

摘要： An energy storage device and structurally enhanced packaging for energy storage cells is provided. The energy storage device includes a number of energy storage cells spaced apart from one another and contained in a lightweight carrier. The energy storage cells and carrier are mechanically coupled together with a structural adhesive forming a unified structure and framework where each connection point acts as a node in a force distribution structure. The structural adhesive can be injected into the volume between the energy storage cells while in a fluid, or semi-fluid, state. While in this state, a retaining form or gasket inside the carrier can prevent the structural adhesive from leaking out of the energy storage device. When in a cured, or hardened, non-fluid state the structural adhesive may adhere to the various components of the energy storage device to mechanically join the component together into a structurally safe package.

摘要： A device for charging an energy storage device includes a controller to initiate a charging operation for the energy storage device and control, during a first stage of the charging operation, a thermal control system to direct a first volume of the thermal mass along a first flow path to heat the energy storage device to a first desired temperature. The controller controls, during a second stage of the charging operation, the thermal control system to direct a second volume of the thermal mass along a second flow path to cool the energy storage device from the first desired temperature towards a second desired temperature.

摘要： An energy storage device including a staggered energy storage cell internal array with two-dimensional inline terminal edges is provided. The energy storage cells in a battery module may be staggered in an internal array, such that a first row of cells in a line are spaced apart, or offset, in a first direction from an immediately adjacent second row of cells in a line, and wherein a first cell in the second row of cells is offset from a first cell in the first row of cells in a second direction orthogonal to the first direction. In some cases, at least two adjacent rows in the battery module may include energy storage cells that are offset from one another but aligned in one direction, such as, the second direction. A mechanical frame may define the arrangement of the energy storage cells relative to one another.

摘要： Methods and systems are provided for managing multi-battery systems, such as those utilized in an electric vehicle. Multi-battery systems comprise batteries providing power in parallel, thereby making each battery available to the vehicle and avoiding the weight of transporting a backup battery. The methods and systems provided allow for a fault in one battery, in a parallel configuration with at least one other battery, to be detected and managed.

摘要： Embodiments of the present disclosure are directed to providing temporary, additional cooling to one or more elements of the vehicle on an as needed basis, e.g., under extreme conditions, when additional cooling is required or predicted to be needed, etc. According to one embodiment, the RC can be “overclocked” or “supercharged” to provide short-term, high output cooling performance under such conditions. For example, if the cooling system is a 10 kW system, it is increased to 15 kW for a short time period by increasing the electrical current and/or frequency to increase the torque and/or speed of the motor driving the RC. According to one embodiment, the cooling system can also be adapted to more effectively utilize the available cooling capacity, either the standard capacity to temporarily increased capacity, by directing the air or liquid coolant to one or more components in need of extra cooling.

摘要： According to one embodiment, a fully-autonomous vehicle, when properly equipped, can be used to clear snow, hail, leaves, and/or other debris from a driveway, roadway, parking lot, etc. For example, a vehicle capable of fully autonomous operation can operate in a “snow plow mode.” In such operations, the vehicle can identify, or be informed of, weather conditions such as snow that would impede travel on paved surfaces such as driveways and roads. When such conditions exist and if the vehicle is properly equipped with a plow or other snow removal equipment, the vehicle and operate in an autonomous manner to clear the user's driveway and/or one or more other driveways, roadways, parking lots, or other paved surfaces depending upon prior permission from the vehicle's owner and based on a variety of factors.
