  • Patent number: 12005801
    Abstract: A method, apparatus and computer program product resolve the problem of unbalanced loads in an EVSE cluster of multiple EVSE charging stations. A signal is provided to the EVSEs identifying which phase of the three-phase power source has the highest current. When one of the EVSEs in the cluster determines whether it is connected to an EV's on board charging device, determines whether it is already charging the connected EV, and determines whether the EVSE is using the phase that has the highest current, then the EVSE may transmit a cluster load balancing control signal as a control pilot signal to the EV's onboard charging device to adjust the charging rate of the current that the EV is consuming from the EVSE.

  • Patent number: 11999251
    Abstract: A charging station assembly capable of generating and delivering a conditioned airflow while charging a battery of a vehicle. The temperature and flow rate of this conditioned airflow may be controlled based on the ambient conditions and battery status. The conditioned airflow may be directed toward an outside heat exchanger of a refrigerant system of the vehicle to enhance capacity. The conditioned airflow may also be routed to a battery pack for direct cooling or heating through additional ventilation system. In hot ambient conditions, the charging station provides cool air to facilitate battery cooling. In cold ambient conditions, the charging station provides hot air to facilitate battery heating. This charging station assembly shifts the load from the vehicle refrigerant system to the charging system, thereby improving battery thermal management capability, while eliminating the need for an oversized refrigerant system.

  • Patent number: 11973365
    Abstract: An inverter and battery charger system that uses no power magnetic components to convert DC power supply from a plurality of batteries to AC power and achieves very high efficiency and small size. The inverter takes advantage of the different voltages in a series string of batteries to create small voltage steps to approximate a sinewave or other waveforms. By changing the timing where the voltage steps are selected, different frequencies can be obtained. The low frequency operation of the inverter produces little radio frequency interference. The battery charger applies charging current to the various nodes in the series string of battery cells to charge each one as needed to accommodate the differing levels of discharge used to make a sinewave or other waveform.
