摘要： The present invention is directed to a battery management system for managing one or more second-life battery packs. The system comprises one or more buffer modules. Each buffer module is configured for coupling to a corresponding battery pack. Each buffer module is operatively configured to determine a type of battery pack upon detection of the corresponding battery pack being coupled thereto. Each buffer module includes a battery pack controller for controlling charge and discharge cycles for each battery pack based on the type of battery pack as determined by the corresponding buffer module. Each buffer module includes a bi-directional DC to DC converter for converting a voltage input from the corresponding battery pack to a predetermined system output voltage.

摘要： A charger for a vehicle includes a power factor correction (PFC) stage to convert AC input power to DC power; an inverter stage; and a transformer having first, second, and OBC coils, each being magnetically coupled for transmitting power therebetween. The OBC coil is connected to the inverter stage, a high-voltage (HV) power converter is connected to the first coil to charge an HV battery connected thereto, and a low-voltage (LV) power converter is connected to the second coil to charge an LV battery connected thereto. The charger is operable in an onboard charger (OBC) mode to transfer the input power to charge the HV battery from the AC input power. The charger is also operable in a DC-DC mode to transfer power from the HV battery to the LV battery, and a wireless power transfer (WPT) mode to receive power from a transceiver coil for charging the HV battery.

摘要： A transmitter assembly is useful in optimizing the delivery of wireless power to a plurality of receivers. Each receiver measures its own battery need for power and transmits that measurement as a request to the transmitter. The transmitter is configured to normalize and compare battery need requests. The transmitter then allocates pulses of wireless power among the requesting receivers according to their battery need.

摘要： A method is provided for controlling a discharge of a battery pack that supplies power to a portable electronic device. The battery pack has one or more cell blocks each having a plurality of battery cells connected in parallel. The method includes the following steps. Determining, for each of the one or more cell blocks, a value of a first supply current flowing through a first battery cell that has the smallest capacity among the plurality of battery cells. Comparing, for each of the one or more cell blocks, the value of the first supply current with a first overcurrent value of the first battery cell to detect overcurrent in the first battery cell. Generating, in response to detecting the overcurrent in the first battery cell of any of the one or more cell blocks, a first overcurrent signal to reduce the power supplied to the portable electronic device.
