Digital Energy Meter - Black & White (EV Charging)

A precision-built digital energy meter designed for real-time EV charging monitoring, delivering accurate electrical data, overload protection, and memory retention for safe and reliable single-phase EV charging.

Key Capabilities

Performance & Design

• Bright LCD display shows all critical electrical parameters required for safe and accurate EV charging
• Designed to continuously monitor voltage, current, power draw, energy consumption, frequency, and power factor in real time
• Smart overload indication alerts users when EV load exceeds safe operating limits, helping prevent overheating or wiring damage
• Resettable energy counter allows accurate tracking of individual charging sessions
• Built-in memory retains kWh readings and backlight state even during power outages
• Supports external CT sensor up to 100A for high-current EV applications
• EV-grade internal components engineered for long-term, continuous charging environments
• Simple single-phase wiring enables easy integration and direct replacement for existing Wundercurrent chargers

Electrical Parameters Explained

• Voltage (V): Displays socket voltage in real time. Below ~180V EVs may charge slowly/refuse; above ~250V risk of heating or charger cut-off.
• Current (A): Shows how much current the EV is drawing. Helps verify charging speed, detects wiring/socket issues, and prevents overload.
• Power (W / kW): Displays real-time power consumption. Useful for checking charging speed and identifying fluctuating supply.
• Energy Consumption (kWh): Shows total electricity units consumed. Enables accurate cost calculation and billing verification (ideal for hotels, resorts, workplaces, shared charging).
• Frequency (Hz): Normal supply should be close to 50 Hz (India). Unstable frequency can cause EV charging interruptions and protects sensitive EV electronics.
• Power Factor (PF): Healthy EV charging typically requires PF between 0.95–1.0. Low PF indicates wasted electricity and inefficient charging.
