摘要： A protection circuit for a capacitive filter for a multi-voltage system includes a first capacitor electrically connected between a first connection point at a first electrical potential and a second connection point at a second electrical potential and a second capacitor electrically connected between the second connection point and a third connection point at a third electrical potential. The first electrical potential is greater than the second electrical potential and the third electrical potential is less than the second electrical potential. The third electrical potential may be electrical ground. A controller circuit monitors a voltage differential across the first capacitor and the second capacitor and, based on the voltage differential meeting a threshold condition, controls a switch to disconnect one or both of the first capacitor and the second capacitor.

摘要： A system for generator-based charging of a battery module may include the battery module, a sensor located adjacent the battery module, a generator controller comprising a processor and a non-transitory memory device storing instructions. The instructions, when executed by the processor, cause the generator controller to analyze one or more sensor signals received from the sensor. The sensor signals may correspond to a condition of the battery module. The generator controller may then calculate, based on the one or more sensor signals, a generator current value for use in charging the battery module. Next, the generator controller may generate a control signal comprising a command that may cause the generator to provide a charging current having the current value.

摘要： A vehicle electrical system comprises a generator which provides electrical power to an electrical load. The generator includes two field coils. A first switch circuit is coupled with the first field coil and a second switch circuit is coupled with the second field coil. A control device, included in the electrical system, operates the first and second switch circuits to regulate the generator output voltage and, in the alternative, to further reconfigure and/or deactivate the switch circuits based on their operating states. The generator maybe further coupled with an electrical energy absorbing device and the control device maybe further configured to operate on a switch, coupled with the electrical energy absorbing device, in response to a shutdown condition, RPM, rate of change of RPM, and voltage transient.

摘要： A vehicle electrical system comprises a generator providing electrical power to a first and a second electrical subsystems at a regulation voltage. A control device ascertains the voltage of the first electrical subsystem, the voltage of the second electrical subsystem, and/or the electrical current to the second electrical subsystem and utilizes a switch module to ensure that the voltage of the first electrical subsystem remains at a predetermined voltage. The control device may be further configured to regulate the output voltage of the generator at the regulation voltage and further to change the regulation voltage as a function of the generator output voltage and voltage of the second electrical subsystem and/or as a function of the electrical current to the second electrical subsystem.

摘要： A system for generator-based charging of a battery module may include the battery module, a sensor located adjacent the battery module, a generator controller comprising a processor and a non-transitory memory device storing instructions. The battery modules include one or more battery types, such as lithium ion batteries.

The generator controller calculates a generator current value for use in charging the battery module. Next, the generator controller may generate a control signal comprising a command that may cause the generator to provide a charging current having the current value. The control signal is generated using a first control loop associated with a battery voltage and a second control loop associated with a battery current.
