US 2025/0050776 A1 · ELECTRIC VEHICLE STATION MANAGEMENT SYSTEM

Abstract

A power regulator device, a power distribution device and related methods and systems for managing power consumption in electric vehicle supply equipment (EVSE) stations. The power regulator device includes an interconnector attached to an EVSE cable, a storage module for receiving a modulation configuration, and a filtering module for intercepting and altering the signal transmitted from the EVSE station to the electric vehicle. The power distribution device is configured to receive a load configuration and a list of EVSE controllers, measure the total load, and communicate modulation configurations to the EVSE controllers to manage power consumption. The system, designed to operate on a mesh network, includes multiple EVSE stations, power distribution devices, and a centralized monitoring agent for managing and controlling power consumption across the EVSE stations.

Dependent claims

A power regulator device for altering a signal transmitted over an electric vehicle supply equipment (EVSE) cable, the power regulator device comprising:

an interconnector attaching to the EVSE cable having a front component leading to an electric vehicle and a back component leading to an EVSE station;
a storage module configured to receive a modulation configuration;
and
a filtering module configured to:
intercept the signal from the EVSE station;
and
output an altered signal according to the modulation configuration towards the electric vehicle, thereby causing the electric vehicle to consume less power than by outputting the signal from the EVSE station.

4 more elements

A power distribution device for distributing power across a plurality of electric vehicle supply equipment (EVSE) stations, comprising:

a storage module configured to:
receive a load configuration comprising a high-power threshold and a high-power recovery threshold;
and
receive a list of downstream EVSE controllers managed thereby, EVSE controllers comprising power regulator devices and EVSE control planes;
and
at least one processor module configured to:
compute a power reduction configuration for at least one of the downstream EVSE controllers upon measuring that a total load has reached the high-power threshold;
and
compute a power restoration configuration for the at least one of the EVSE controllers upon subsequently reaching the high-power recovery threshold.
a network communication module configured to:
communicate a modulation configuration to one or more of the downstream EVSE controllers, causing the downstream EVSE stations to consume no more than permitted for the power distribution device.

8 more elements

A system for managing power consumption of electric vehicle supply equipment (EVSE) stations comprising:

a plurality of EVSE stations, each being connectable to an electric vehicle and configured using a EVSE controller, the EVSE controller comprising a power regulator device or a EVSE control plane;
one or more power distribution devices configured to:
receive a load configuration comprising a high-power threshold and a high-power recovery threshold;
