  • Publication number: 20250033493
    Abstract: A battery electric vehicle (BEV) charging station includes at least one power module having a plurality of switches that rectify alternating current (AC) electrical power received from a power grid into direct current (DC) electrical power supplied to a BEV; at least one switched mode power supply (SMPS) internal to the power module; and operational equipment electrically connected to the SMPS in the power control module.

  • Publication number: 20250033490
    Abstract: A direct current (DC) fast charger for charging batteries of electric vehicles (EVs) that includes a primary circuit, with seven bidirectional switches, electrically linked to a primary wire of a transformer and configured to receive alternating current (AC) voltage; and a secondary circuit, including a plurality of diodes arranged to rectify AC voltage into DC voltage, that is electrically linked to a secondary wire of the transformer, such that the DC fast charger unidirectionally converts AC voltage received at the primary circuit into DC voltage output by the secondary circuit.

  • Patent number: 10004142
    Abstract: A circuit board assembly includes a primary circuit board extending in a first plane and configured to control electrical distribution and a secondary circuit board extending in a second plane, different from the first plane, with the primary and secondary circuit boards spaced from and substantially parallel with one another, and with the secondary circuit board abutting the primary circuit board such that the primary and secondary circuit boards are electrically coupled to one another. The circuit board assembly further includes at least one sensor disposed on the secondary circuit board and electrically coupled to the secondary circuit board such that the at least one sensor is electrically coupled to the primary circuit board through the secondary circuit board, with the secondary circuit board positioning the at least one sensor in proximity with the at least one magnet for detecting the position of the at least one magnet.

  • Patent number: 9879596
    Abstract: An actuator assembly moves an output shaft. The actuator assembly includes a housing having at least first, second, and third sections at least partially defining first and second cavities, with the third section between the first and second sections. A motor assembly has a rotatable drive shaft and is coupled to the third section. The motor assembly is at least partially disposed in the first cavity and the drive shaft is at least partially disposed in the second cavity. At least one drive gear is within the second cavity and is fixed to the drive shaft. At least one driven gear is within the second cavity and is coupled with the output shaft. The at least one driven gear is coupled to the third section of the housing and is rotatably coupled with the at least one drive gear to transmit rotation from the drive shaft to the output shaft.
