  • Patent number: 10270265
    Abstract: An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.

  • Patent number: 10263413
    Abstract: A single-phase or multi-phase feed line is connected to a charging connection of the charging station, via which feed line the charge current flows to the charging connection of the charging station regardless of the load capacity identifier of the charge cable. An overload protection device is connected to and monitors the feed line. The overload protection device is an automatically switching overload protection device in which at least one identifier-specific trigger criterion is stored for each of at least two load capacity identifiers of the charging cable. The overload protection device is capable of automatically selecting the identifier-specific trigger criterion assigned to the load capacity identifier depending on the load capacity identifier of the charging cable, and of shutting off a switching device of the overload protection device arranged in the feed line depending on the selected trigger criterion.

  • Patent number: 10252626
    Abstract: A charger with a power converting inverter that can be reliably stopped by a forced stop signal, without causing an increase in part quantity. A control power supply supplies voltage to gate drive circuits, which supply gate signals to an inverter. The control power supply includes a transformer, a power supply control circuit IC that repeatedly opens and closes a primary side circuit formed by a primary winding of the transformer and an auxiliary machine power supply being connected in series, and a rectifier that generates power supply voltage to be supplied to the gate drive circuits by rectifying AC voltage generated in a secondary winding of the transformer. The power supply control IC turns off a FET in accordance with a forced stop signal, thereby forcibly switching the primary side circuit to an open state, and stopping the supply of power supply voltage to the gate drive circuits.

  • Patent number: 10209090
    Abstract: A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. By default, each portable electrical energy storage device is disabled from accepting a charge unless it receives authentication information from an authorized collection, charging and distribution machine, other authorized charging device, or other authorized device that transmits the authentication credentials. Also, by default, each portable electrical energy storage device is disabled from releasing energy unless it receives authentication information from an external device to which it will provide power, such as a vehicle or other authorization device.
