Patent number: 11811248Abstract: 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.Type: GrantFiled: July 21, 2016Date of Patent: November 7, 2023Assignee: C.E.

Patent number: 8432069Abstract: A vehicle electrical system comprises a generator and a control device coupled with the generator and operable to protect the generator from catastrophic failure while providing the electrical load in the electrical system with sufficient electrical power. The control device determines a loss of symmetry between two alternating phase signals generated by a first and second phase windings of a single or multiple stator generator. In particular, the control device determines a first and second average values of two of the two or more alternating phase signals and either limits or ceases the total electrical output current of the generator, via a generator output power controller, when the first average value differs from the second average value by a predetermined value. The control device may alternatively be configured to generate an error signal without varying the generator's total electrical output current even in the event of a malfunction.Type: GrantFiled: June 8, 2012Date of Patent: April 30, 2013Assignee: C.E.
