  • Publication number: 20240131955
    Abstract: A method and a system for controlling battery swapping of a vehicle and a vehicle are provided. The method includes: receiving, by a vehicle control unit (VCU), a battery swapping instruction, and transmitting the battery swapping instruction to a battery manager when the vehicle is in a high-voltage power-on state; transmitting, by the battery manager, an enable instruction to a direct current (DC) charger assembly in response to the received battery swapping instruction; and performing, by the DC charger assembly, a starting operation in response to the enable instruction, so as to provide a power supply voltage to a vehicle load after an electrical connection between a power battery pack and a high-voltage circuit of the vehicle is cut off during battery swapping of the vehicle.

  • Publication number: 20240100987
    Abstract: A method for controlling automatic battery swapping of a rail vehicle, includes: receiving vehicle information sent by the rail vehicle; determining whether the rail vehicle has a battery swapping need based on the vehicle information of the rail vehicle; in response to determining that the rail vehicle has the battery swapping need, determining a target battery swapping station according to the battery swapping need; and sending a battery swapping notification signal and a vehicle control signal to the rail vehicle, and sending a battery swapping request signal to the target battery swapping station, where the battery swapping notification signal includes position information of the target battery swapping station, the vehicle control signal controls the rail vehicle to travel to the target battery swapping station, and the battery swapping request signal includes identification information of the rail vehicle and requests the target battery swapping station to swap a battery pack for the rail vehicle.

  • Publication number: 20120244282
    Abstract: A vapor deposition source for vaporizing a material has a body forming an interior chamber, at least one crucible in the interior chamber, and a divider that divides the interior chamber into a transport channel and a distribution channel. To deposit vapor on an underlying substrate, the deposition source also has a plurality of exit orifices formed in the body adjacent to the distribution channel. The divider has a set of divider apertures between the transport channel and the distribution channel. This divider aperture is positioned generally symmetrically within the interior chamber.
