How to Find Your EV Charging AmperageUpdated 11 hours ago

What is Amperage?

Amperage (measured in Amps) represents the rate of electrical current flow - think of it as how much electricity is flowing through your charging cable at any given moment.

Simple Analogy - comparing Electricity to a water hose:

• Voltage = The diameter of your water hose
• Amperage = The speed at which the water flows through per second
• Power = Voltage x Amperage. Think of Power as the volume of water flowing through (larger diameter* faster speed = more volume moving through the hose)

Why Amperage Matters:

• Determines your charging speed
• Must stay within safe limits for your circuit
• Exceeding limits can trip breakers or cause safety issues

Important: Who Controls Charging Amperage?

The Smart Splitter does NOT control charging amperage.

Amperage is controlled by either:

1. Your Electric Vehicle (Tesla, BMW, etc.)
2. Your EV Charger/EVSE (Level 2 charger unit)
3. Or both working together

The Smart Splitter simply monitors and manages power distribution - it cannot adjust how much current your EV draws.

How to Find Your Current Charging Amperage

Method 1: Check Your EV Charger Display

Many Level 2 chargers show current amperage on:

• LED/LCD display on the unit
• Indicator lights (some models)
• Mobile app (for smart chargers)

Common Displays:

• "32A" or "24A" shown directly
• Light indicators for different amperage levels
• Real-time power draw in kW (divide by 240 to get amps)

Method 2: Check Your Vehicle Settings

Tesla:

• Tap the lightning bolt icon while charging
• Shows current amperage clearly
• Adjustable using slider in car or mobile app

Other EVs with Displays:

• Navigate to charging settings in dashboard
• Look for "Charge Rate," "Current," or "Amperage"
• May show in kW (divide by 240 for amps)

Vehicle Apps:

• BMW, Ford, Chevy, VW, Hyundai apps often show charging status
• Look for "Charging Power" or "Charge Rate"
• Some show real-time amperage during active charging

Method 3: Check Your Charger Specifications

Fixed-Rate Chargers:

• Check the label on your charger
• Look for "Output: XXA" or "XX Amps"
• Common fixed rates: 16A, 24A, 32A, 40A

Adjustable Chargers:

• LENZ: Check DIP switch settings
• Wallbox: Check app settings
• Other brands: Refer to manual for current setting

Method 4: Check Your Owner's Manual

If you're using the charger that came with your vehicle:

• Ford Mobile Charger: Typically 32A (non-adjustable)
• VW Mobile Charger: Usually 32A (non-adjustable)
• Tesla Mobile Connector: Varies by adapter (24A for 14-30, 32A for 14-50)
• Nissan/Chevy: Check specific model documentation

Quick Reference: Is Your Amperage Safe?

Safe Charging Limits (80% Rule):

1Circuit Breaker
2Maximum Safe Charging
330A Breaker
424A or less
540A Breaker
632A or less
750A Breaker
840A or less

What to Do Next

If Your Amperage EXCEEDS Safe Limits:

• Charging above 24A on 30A breaker
• Charging above 32A on 40A breaker
• Charging above 40A on 50A breaker

➡️ See our [Circuit Breaker Tripping Guide] for solutions

If Your Amperage is WITHIN Safe Limits:

But you're still experiencing issues:

• Breaker trips at safe amperage
• Smart Splitter showing error lights
• Intermittent charging problems

➡️ Contact NeoCharge Support - There may be other factors affecting your setup

Common Amperage Scenarios

"My charger says 32A but I have a 30A breaker"

• This is unsafe - exceeds the 24A limit
• Need to reduce amperage or get adjustable charger
• Common issue with Ford, VW chargers

"I don't see amperage anywhere"

• Try charging and check vehicle display
• Calculate from kW: Amps = kW ÷ 0.240
• Contact your EV manufacturer for guidance

"My Tesla shows different amperage options"

• Tesla allows adjustment
• Set to appropriate level for your circuit
• Smart Splitter compatible with all settings

Still Can't Find Your Amperage?

Contact us with:

1. Your EV make and model
2. Your charger brand and model
3. Photos of any labels on your charger
4. Screenshots of your vehicle's charging screen

Our support team can help identify your specific charging rate and ensure safe operation with your Smart Splitter.

Remember

• The Smart Splitter works with ANY amperage within circuit limits
• You MUST know your charging amperage for safe operation
• When in doubt, start with lower amperage and increase gradually
• Safety first - never exceed the 80% rule for your circuit
