1. TECH Overview

Evercurb is a curb-integrated power and data delivery platform that transforms the linear edge of the sidewalk into a continuous, modular utility spine. It provides safe, distributed AC and DC power, along with high-bandwidth communications, to any device located along the street edge, including:

  • Electric vehicles and micro-mobility (cars, vans, e-bikes, scooters)

  • Street lighting, signage, and traffic control devices

  • Sensors, cameras, environmental monitors

  • Vending, kiosks, and temporary event infrastructure

The system is designed to be retrofitted into existing streetscapes or embedded in new construction without disrupting pedestrian circulation or vehicle lanes.

2. System Architecture

Evercurb consists of a set of coordinated subsystems integrated into prefabricated curb modules:

  1. Structural Curb Module

    • Precast concrete, engineered stone, or recycled composite curb sections

    • Internal channels for power, data, and drainage management

    • Standardized curb geometry for compatibility with local DOT and city standards

    • Surface designed to withstand wheel impact, de-icing salts, water, and freeze–thaw cycles

  2. Power Distribution Spine

    • Enclosed busways running longitudinally inside the curb

    • Segregated AC and DC channels

    • Tap points at regular intervals for connection to devices and charging points

    • Integrated overcurrent, ground-fault, and isolation protection

  3. Power Conversion and Control Units (PCUs)

    • Discrete PCUs located periodically (for example every 20–50 meters) within curb modules or adjoining utility vaults

    • AC–DC conversion for DC bus (e.g., 400–800 V DC) and regulated low-voltage DC rails for sensors and low-power devices

    • Bidirectional power electronics that can support grid-interactive loads and future vehicle-to-grid (V2G) functions

    • Local measurement, protection, and switching hardware

  4. Access Ports and Interfaces at the Curb Edge

    • Ruggedized, weather-sealed connection points flush with or slightly inset from the curb face

    • Configurable options including:

      • Fixed charging pedestals

      • Flush sockets and retractable connectors

      • Inductive pads embedded in the road surface near the curb

    • Mechanical locking and access control to prevent vandalism and unauthorized use

  5. Communications and Data Layer

    • Integrated data conduits within the curb for fiber or copper

    • Edge controllers and gateways located in selected modules

    • Support for common protocols such as OCPP for chargers, Modbus / IEC protocols for power management, and IP-based connectivity for sensors

    • Optional integration with cellular small cells or Wi-Fi access points hosted at the curb

  6. Supervisory Platform (Cloud or On-Prem)

    • Centralized monitoring of all curb segments and devices

    • Load management and demand response coordination

    • User authentication, billing, and usage analytics

    • Interfaces for city operations dashboards and third-party service providers

3. Functional Capabilities

3.1 Distributed Power Delivery

  • Primary feed from local distribution grid or building service brought to one or more injection points.

  • Longitudinal bus distributes power along the block, reducing the need for multiple standalone bollards or cabinets.

  • Configurable AC outputs for conventional loads and DC rails optimized for EV and micro-mobility charging, lighting, and electronics.

3.2 Multi-Modal Charging

  • Support for different charging regimes at the same curb spine:

    • Level 2 EV AC charging

    • DC fast charging at selected nodes

    • Dedicated circuits for e-bikes, scooters, and cargo bikes

  • Ability to add or reconfigure charging points without major civil works, using standardized curb access modules.

3.3 Integrated Data and Sensing

  • Continuous data backbone enabling:

    • Environmental sensing (air quality, noise, temperature, humidity)

    • Traffic and occupancy monitoring

    • Infrastructure diagnostics (surge detection, moisture ingress, vandalism)

  • Local edge compute at PCUs for real-time control and reduction of backhaul data loads.

3.4 Smart Load Management

  • Dynamic allocation of available power across multiple devices along a block or district.

  • Prioritization logic (e.g., emergency vehicles, public transit, critical infrastructure) built into the control software.

  • Ability to shape load profiles to respond to peak pricing, grid constraints, or renewable generation patterns.

4. Safety and Compliance

Evercurb is engineered to meet or exceed applicable electrical and civil standards, including:

  • Electrical codes such as NEC for distribution, grounding, and overcurrent protection

  • Standard practices for underground and near-surface power distribution enclosures

  • Ingress protection ratings (targeting IP65 or higher for curb interfaces)

  • Impact resistance standards for vehicle contact and snowplow interaction

  • Slip, trip, and fall safety requirements for pedestrians

Core safety mechanisms include:

  • Segregated compartments for power and data

  • Double or reinforced insulation within bus channels

  • Fast disconnect and isolation in the event of faults or flooding

  • Ground-fault detection and automatic shutdown of individual segments if anomalies are detected

  • Tamper-resistant enclosures and controlled access for maintenance

5. Installation and Maintenance

5.1 Installation

  • Modular curb sections are delivered prefabricated and installed using standard curb setting methods.

  • Power and data bus elements are connected via sealed couplers that maintain continuity across modules.

  • PCUs are placed in accessible but protected locations for service.

  • System can be connected to existing manholes, vaults, or building service entrances to minimize new trenching.

5.2 Maintenance Strategy

  • Hot-swappable curb modules at failure points, allowing replacement with minimal disruption.

  • Remote diagnostics identify failing segments or devices, reducing site visits.

  • Standardized components and mechanical interfaces to simplify inventory and field repair.

6. Scalability and Interoperability

Evercurb is designed as an open, scalable platform:

  • Scalability

    • Can be deployed at the scale of a single block, a corridor, or an entire district.

    • Curbs can be phased in incrementally as streets are resurfaced or rebuilt.

  • Interoperability

    • Supports integration with multiple charger vendors and sensor providers through open protocols.

    • Designed to interconnect with city asset management systems and digital twins.

    • API access for mobility operators, utilities, and researchers to build services on top of the curb network.

7. Use Cases

Representative use cases along a single street or district include:

  • EV and micro-mobility charging lanes along commercial streets.

  • Power and connectivity for outdoor markets, festivals, and seasonal installations without diesel generators.

  • Integrated curb for “complete streets” projects that combine charging, smart lighting, and real-time environmental monitoring.

  • Power and data backbone for automated delivery robots and other emerging street-level autonomy systems.

8. Intellectual Property Position

Evercurb is protected by patents covering the integration of multi-channel power and data distribution in the curbline, modular bus structures, and configurable curb-edge interfaces that support multiple charging and information services from a unified curb spine. The system is differentiated from conventional stand-alone chargers or bollards by:

  • Its continuous, linear distribution architecture at the edge of the sidewalk.

  • The combination of high-capacity power, low-voltage DC, and data in a single curb module system.

  • Configurable, field-replaceable curb interfaces that can support any street-level device without re-excavation.
