  • Publication number: 20240092206
    Abstract: In an example, an electrical vehicle (EV) charger system power platform includes a housing, a transformer, a distribution board, and an electrical safety switch. The housing encloses a volume. The transformer is disposed within the volume and is configured to be electrically coupled to a power source and to generate output power from input power received from the power source. The distribution board is disposed within the volume and is electrically coupled to an output of the transformer. The electrical safety switch is disposed within the volume and is electrically coupled to an input of the transformer and configured to be electrically coupled to the power source.

  • Publication number: 20240075834
    Abstract: A pedestal base may include a skid base and a riser. The skid base may define a cable management system (CMS) opening and a base opening. The skid base may interface with a CMS via the CMS opening. The riser may define a riser opening. The riser may include a sidewall. The sidewall may mechanically interface with an electric vehicle (EV) charger. The riser may mechanically interface with the skid base to position the riser opening proximate the base opening. The skid base and the riser, when mechanically interfaced, may permit a cable to extend between the CMS and the EV charger and to extend through the base opening and the riser opening.

  • Publication number: 20240075835
    Abstract: A pedestal base may include a skid base and a cover. The skid base may define an opening. The skid base may interface with a cable management system (CMS) via the opening. The cover may mechanically interface with an electric vehicle (EV) charger. The cover may also mechanically interface with the skid base. The skid base and the cover may define a volume. The skid base and the cover, when mechanically interfaced, may permit a cable to extend between the CMS and the EV charger and to extend through the opening and the volume.

  • Publication number: 20230347768
    Abstract: In an example, an electric vehicle (EV) charger system power platform includes a base, a transformer, a distribution board, and a communication interface. The transformer is coupled to the base and is configured to be electrically coupled to a power source and to convert an input power from the power source to an output power for the power platform. The distribution board is coupled to the base and is electrically coupled to the transformer. The communication interface is coupled to the base and is configured to communicatively couple the power platform to a communication network.

  • Publication number: 20230347762
    Abstract: In an example, a system to charge electric vehicles includes a power platform, a cable management system (CMS), two or more lead assemblies, and a charger platform. The power platform is configured to receive input power, to generate output power from the input power, and to electrically protect the lead assemblies and the charger platform. The CMS extends from the power platform. The lead assemblies each include a feeder cable electrically coupled to the power platform. The lead assemblies also include a drop line electrically coupled to the feeder cable. Additionally, the lead assemblies are disposed in the CMS. The charger platform is configured to interface with the CMS and support a charging device. The charging device is electrically coupled to the drop line. The charging device includes an electric vehicle charger that is configured to deliver the output power to an electric vehicle.
