    Abstract: A vehicle traction device having at least one energy storage component; at least one traction component; at least one acceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor; and at least one deceleration sensor including a pressure sensor, a motion sensor, a gyroscopic sensor, an accelerometer, and/or a piezoelectric sensor. The at least one acceleration/deceleration sensor is responsive to an operator input, and when the operator input is applied to the at least one acceleration/deceleration sensor, the energy traction device is signaled to transfer energy from the at least one energy storage component to the forward propulsion of the vehicle, or vice versa, using the at least one traction component. The vehicle traction device may be incorporated into, for example, a wheel, a motor, and/or a transmission.

    Abstract: Disclosed herein is an apparatus for controlling the spacing of battery cells. The apparatus monitors the temperature of the battery cells, and when a battery cell temperature value exceeds a threshold, changes the configuration of the battery cell spacing from an initial closed configuration to an open configuration using a spacer mechanism. The spacing during the closed configuration is a first distance between the battery cells, and during the open configuration is a second distance between the battery cells. The second distance is substantially large than the first distance to position the lithium ion cells further apart, lowering the probability a thermal runaway event propagating from one cell to adjacent cells. The spacer mechanism may include a telescoping or expanding frame, a motor, one or more sensors, and a controller configured to operate the mechanical spacer.
