    摘要： A method for accurately estimating battery capacity based on a weighting function is provided. The disclosed system monitors battery current and uses the monitored battery current to calculate the state of charge (SOCbyAh) of the battery. The system also measures the open circuit voltage (OCV) of the battery when the system is at rest, rest being determined by achieving a current of less than a preset current value for a period of time greater than a preset time period. The state of charge of the battery is calculated from the OCV (SOCbyOCV). The weighting function is based on ΔSOCbyAh and ΔSOCbyOCV, where ΔSOCbyAh is equal to SOCbyAhFirst time minus SOCbyAhSecond time, and where ΔSOCbyOCV is equal to SOCbyOCVFirst time minus SOCbyOCVSecond time. The weighting function also takes into account the errors associated with determining SOCbyAh and SOCbyOCV.

    摘要： A method and apparatus is provided for determining when a battery, or one or more batteries within a battery pack, undergoes an undesired thermal event such as thermal runaway. The system uses an insulated conductive member mounted in close proximity to, or in contact with, an external surface of the battery or batteries to be monitored. A voltage measuring system is coupled to the conductive core of the insulated conductive member, the voltage measuring system outputting a first signal when the temperature corresponding to the battery or batteries is within a prescribed temperature range and a second signal when the temperature exceeds a predetermined temperature that falls outside of the prescribed temperature range.

    摘要： A charge connector latching mechanism integrated into a vehicle's charge inlet is provided, where the latching mechanism includes a retractable latching pawl. The retractable pawl is configured to be positioned in at least a first, default position where the pawl extends through an inlet surface of the charge inlet, and a second position where the pawl is retracted and does not extend through the inlet surface. In the first position the retractable pawl prevents insertion of a charge connector into the charge inlet if the charge connector is uncoupled from the inlet, and prevents removal of the charge connector if the charge connector is coupled to the inlet. In the second position the retractable pawl allows insertion/withdrawal of the charge connector into/from the charge inlet. The front surface of the retractable pawl may include a nub configured to fit within a recess within the front face of the charge connector.
