  • Patent number: 10471836
    Abstract: A vehicle-mounted charging system is provided that can charge a battery regardless of the charging method and prevent an abnormal current from occurring between a vehicle and a charging station. A first charging controller, controls charging in accordance with a first charging method, communicates with a first charging apparatus via a charging cable connected to a first inlet, and charges a battery by turning on a DC cutoff relay, provided on a power supply path from the first inlet to the battery. If it is determined that charging is to be performed in accordance with a second charging method, a charging control unit relays communication between a second charging apparatus and the first charging controller. The charging control unit performs control to delay the timing of actually turning on the DC cutoff relay relative to the timing at which the first charging controller turns on the DC cutoff relay.

  • Patent number: 10457270
    Abstract: A method for controlling a hybrid starter and generator (HSG) is applied to an eco-friendly vehicle. The method includes HSG torque-output limiting control, and in particular, the HSG torque-output limiting control is divided into an HSG regeneration mode and an HSG driving mode in which output limitation of the HSG 3 is performed after torque limitation of the HSG 3. Furthermore, the HSG regeneration mode includes: a former regenerative torque output control in which an engine RPM is converted by a controller 10 into regenerative torque output of the HSG 3 for about 1 second when an engine starts idling to charge a battery, and a latter regenerative torque output control in which the engine RPM is converted into the regenerative torque output of the HSG 3 after 1 second to about five seconds to continue to charge the battery 7, and an HSG driving mode.

    Abstract: The present disclosure relates to method for use with a system having first and second uninterruptible power supplies (UPS 1 and UPS 2), and where the two UPSs are connected across a DC+ and a DC? terminal of a common battery, and where a neutral imbalance between neutral lines of the two UPSs has been corrected, giving rise to a current flow from a DC? bus of one of the UPSs to a DC? bus of the other one of the UPSs. The method corrects for a nominal DC reference voltage for one of the UPSs to eliminate the current flow to the DC? bus of the other UPS.

  • Patent number: 10424956
    Abstract: A fob for a passive entry passive start (PEPS) system includes a LF receiver, an UHF transmitter, an UWB transceiver, a primary battery to power the receiver and the transmitter, a rechargeable secondary battery to power the transceiver, and a controller. The controller may cause the primary battery to recharge the secondary battery when the secondary battery has a low charge. The controller may cause the transmitter to transmit an indication to a base station of the PEPS system that the primary battery has a low charge. This indication is to alert a user to replace the primary battery. The controller may cause the transmitter to transmit an indication that the secondary battery is dead when the secondary battery is detected to be dead. This indication is to alert the base station that PEPS communications of the fob will not involve the transceiver.

  • Patent number: 10401436
    Abstract: A method is described for managing an operating state of a battery energizing a mobile device. Active elements of a “gas gauge” IC component of the mobile device are configured or programmed based on instructions related to tracking capacity aging of the battery. An event is targeted based on the configured or programmed instructions. The targeted event corresponds to reaching an end of a discharge state of the battery, or to reaching a midpoint (relative to full charge) of a charging state of the battery. A relaxation state is induced in the battery upon the targeted event occurring.
