Hardware Design Principles

DeCharge chargers are engineered for real-world durability, modularity, and ease of deployment. Whether installed in a residential garage, a rural roadside, or a public mall parking lot, the hardware is designed to be reliable, serviceable, and future-ready.

This section outlines the guiding principles, physical design attributes, and embedded technologies that make DeCharge hardware uniquely suited to a distributed, community-powered infrastructure model.

Real-World Design Philosophy

DeCharge hardware is built to operate reliably in a wide range of physical environments and use cases. Key design goals include:

• Rapid deployment with minimal tools or technical support

• Compatibility with standard residential and commercial power supplies

• Protection against dust, water, temperature, and tampering

• Onboard diagnostics and remote controllability

• Longevity across 5-7 years with minimal maintenance

Each charger is developed with mass deployment in mind - ensuring every unit is easy to install, monitor, and maintain at scale.

Modular Component Architecture

All DeCharge devices follow a modular hardware design. This enables faster manufacturing, simplified part replacement, and streamlined field servicing.

Core components include:

Component	Functionality
Power Control Unit	Handles energy input, safety cutoff, and delivery
PCB with OSEM module	Tracks energy usage and uptime securely
Communication Module	Enables Wi-Fi, 4G/5G, or LAN connectivity
Enclosure & Mounting	Protects internals and supports pole/wall mounts
Diagnostic Ports	Used for testing, firmware updates, reset

Each module is separately replaceable or upgradeable, allowing DeCharge to issue OTA (over-the-air) software updates or field-level part replacements without decommissioning the entire unit.

Smart Metering and Security

Every charger includes a secure metering chip. This system enables:

• Precision energy logging (kWh per session)

• Timestamped session data and usage history

• Local signing of every transaction

• Tamper detection and error flagging

Because this metering is built into the hardware itself, DeCharge does not rely on external reporting, manual auditing, or trust-based verification. Each device autonomously generates proof of its own activity.

Environmental and Electrical Protection

DeCharge chargers are built to handle diverse and unpredictable field conditions. All hardware units include:

• IP65 (or higher) rated enclosures to protect against dust and rain

• Ventilation systems and thermal cutoffs to manage overheating

• Ground fault detection and auto-shutdown circuits

• Residual Current Devices (RCDs) to prevent electrical shock

• Overvoltage protection for power surges

Installers are guided to place chargers under shade or canopies when exposed to extreme sunlight. Chargers also include LED indicators for real-time operational status and basic fault diagnosis.

Connectivity and Communication

Each charger is designed to be online 24/7 through at least one of three supported communication modes:

• 4G/5G SIM slot (supports major telecom providers in India, Europe, and North America)

• Wi-Fi (requires dedicated router with minimum 100 Mbps bandwidth)

• LAN (for large sites, hubs, or Titans)

Connectivity allows each unit to:

• Transmit telemetry to the DeCharge backend

• Receive OTA updates

• Be remotely restarted, locked, or diagnosed

• Stream live status data to the host dashboard

Offline buffer storage allows for short-term operation if the internet is temporarily lost, with queued data uploaded once the connection is restored.

Mounting Options and Power Interface

To accommodate different site conditions and charger models:

Model	Mount Options	Input Requiremen
Mini	Wall-mounted	230V, 16A (1-Phase)
Beast	Wall or Pole	230V, 32A (1-Phase)
Titan Mini	Ground Plinth	415V, 3-Phase, 72A
Titan	Ground Plinth	415V, 3-Phase, 90A

Mounting kits are included for both standard and delegated installations. Brackets, bolts, and strain relief fittings ensure long-term mechanical safety.

Designed for Future Integration

DeCharge hardware is not static. It includes architecture and spare I/O interfaces for future integration with:

• Energy storage systems (batteries or BESS)

• Rooftop or pole-mounted solar panels

• Dynamic pricing controllers or smart meters

• Peer-to-peer energy trading modules

• Microgrid or vehicle-to-grid (V2G) ecosystems

This ensures that even entry-level devices can evolve with the network, enabling gradual migration toward more advanced use cases without hardware replacement. The modular design also allows Titan Mini and Titan to share a common chassis and communication stack, streamlining integration, diagnostics, and servicing across power classes.

Deployment-Ready Packaging

All DeCharge chargers are shipped in ruggedized packaging with:

• Pre-registered QR codes mapped to owner accounts

• Cable size, breaker rating, and mounting instructions

• User-specific configuration if ordered via delegation

• Printed quickstart and digital onboarding guide

Upon delivery, most chargers can be installed in under 90 minutes by a certified electrician or delegated partner.

DeCharge’s hardware design reflects its larger mission to enable scalable, decentralized infrastructure without complexity. Each charger is a robust, modular node designed to serve users and communities reliably for years to come.
