WunderCurrent® Digital Energy Meter — Complete Monitoring for Safe EV Charging

The WunderCurrent® Digital Energy Meter is a high-precision AC monitoring module designed to help EV owners track all essential electrical parameters during charging. With 6-in-1 real-time monitoring, this meter ensures safer, more efficient and more accurate charging—at home, resorts, offices or outdoor locations.

 Key Highlights

• 6-in-1 Real-Time Monitoring (Accuracy ±1%)

Displays:

  • Voltage (V)
  • Current (A)
  • Active Power (W/kW)
  • Energy Consumption (kWh)
  • Frequency (Hz)
  • Power Factor (PF)

Ensures your EV receives proper, stable power supply.

• Smart Safety Alerts + Memory Retention

  • Overload indication when EV load exceeds safe limit
  • Stores kWh readings even during power cuts
  • Backlight memory for uninterrupted usage
  • Resettable energy counter

• EV-Grade Long-Life Construction (80–260V AC)

  • Supports external CT sensor up to 100A
  • Designed for continuous EV charging environments
  • Heavy-duty internal components
  • Simple wiring — direct replacement for W2 Ultra & W3 Ultra meters

Technical Explanation

1. Voltage (V)

Shows your socket’s voltage.

  • Below 180V: Many EVs will not charge or charge slowly
  • Above 250V: Risk of heating or charger cut-off
    Correct voltage ensures stable charging.

2. Current (A)

Indicates how much current your EV is drawing.

  • Helps verify charging speed
  • Detects wiring issues
  • Prevents overload

3. Power (W/kW)

Shows real-time power draw.
 Useful for:

  • Checking charging speed
  • Identifying socket issues
  • Monitoring fluctuating supply

Energy Consumption (kWh)

Total electricity units consumed during an EV charging session.
 This helps you:

  • Track the exact charging cost
  • Prevent incorrect billing at hotels, resorts, workplaces
  • Monitor your EV’s charging efficiency
  • Calculate your total electricity expense easily using:
    Units (kWh) × Your Electricity Provider’s Per-Unit Rate
     (Example: If meter shows 4.2 kWh and your per-unit rate is ₹8 → 4.2 × 8 = ₹33.6)

5. Frequency (Hz)

Should be near 50 Hz in India.

  • Unstable frequency = EV may refuse to charge
  • Protects EV electronics

6. Power Factor (PF)

Healthy EV charging requires 0.95–1.0 PF.

  • Low PF = wasted electricity + slow charging
  • Indicates poor socket or wiring quality
  • Helps maintain charging efficiency
