A method and apparatus for determining coolant leakage in a vehicular propulsion system battery. An AC isolation resistance test is used to determine whether an isolation fault has occurred within the battery, but can also determine the capacitance of the circuit or system, which can further determine the coolant leakage levels of the vehicular propulsion system battery. This eliminates having an additional device to measure the coolant leakage.
Electrical System With High-Voltage System Lockout Function

International Classification:
H02J 7/00 B60L 11/18 H02P 27/06
Abstract:
An electrical system includes a battery disconnect unit (BDU) connected to a rechargeable energy storage system (RESS) via a high-voltage bus. The BDU has one or more contactors that close responsive a low-voltage drive current to thereby connect the RESS to the high-voltage bus. A low-voltage drive circuit conducts the drive current to the contactor(s). Opening of a low-voltage connection interrupts the drive current and causes the contactor(s) to transition from the closed state to an open state. The contactor(s) open in response to interruption of the drive current to thereby disconnect the RESS. The contactor(s) may be closed again after a lockout safety procedure, such that reestablishing the electrical connection does not itself re-energize the high-voltage bus. An electrified powertrain includes a transmission, electric machine, power inverter module, and the above-noted electrical system.
Battery Module With Active Cell Balancing Using Energy Storage Element And Two Tiers Of Switches

International Classification:
H02J 7/00
Abstract:
A battery system includes a battery module, an active cell balancing circuit, and a battery controller. Each cell has diametrically-opposed positive and negative cell tabs. The circuit includes voltage sensors and, at each end of the battery module, first and second tiers of switches and an energy storage element. Each voltage sensor is located between a different pair of adjacent cells. The controller receives measured voltages from the sensors indicative of an electric potential between adjacent battery cells. Responsive to the measured voltages, the controller commands the first tier to selectively connect or disconnect designated pairs of cells to the corresponding second tier. The controller also commands the second tier to selectively connect or disconnect the designated cells to a corresponding energy storage element. This action shuttles energy between the designated pairs of battery cells to balance a state of charge.
