How to Fix EV Charger Not Charging

When you return to your driveway your electric vehicle remains completely empty despite parking with an exhausted battery because the charger did not provide any charge throughout the night. Your vehicle battery remains empty and you cannot understand the reason behind this situation.

Each EV owner experiences this irritating situation at least once and it usually occurs during the most urgent times when you need your vehicle.

Fear not because this guide will assist you in locating the charger defect while restoring your car’s functionality after an EV charging system failure.

Top Causes of EV Charger NOT Charging

Problem with Charging Connector Latch Mechanism:

• Connector not fully engaged or not “clicking” into place.
• Dirt, debris, or corrosion affecting latch functionality.
• Misalignment from improper insertion or uneven surfaces.
• Wear and tear or mishandling of the EV latch mechanism.

Incompatible Connector:

• Newly purchased connectors may not be compatible with your vehicle.
• Common issue with third-party or non-OEM connectors.
• Issues can arise if the connector is not suited for Level 2 chargers or DC fast chargers.

Charger Overheating:

• Continuous use without proper cooling or breaks.
• Poor ventilation around the charging station.
• Overheated EV chargers trigger safety protocols that stop the charging process.
• Error codes or blinking lights indicating overheating.

Software/Firmware Issues:

• Outdated software on the EV or charger leading to charging errors.
• Charger not initiating or stopping abruptly due to software glitches.
• Failure to connect or initiate charging sessions due to outdated firmware.

Power Supply Issues:

• Voltage fluctuations or insufficient power delivery to the charger.
• Incorrect circuit breaker setting or faulty wiring causing inconsistent power flow.

Faulty Charging Station:

• Problems with the EVSE (Electric Vehicle Supply Equipment) such as internal failures.
• Damage to the station’s power supply, circuit board, or connectors.
• User error in handling the charging station setup (e.g., incorrect installation or improper grounding).

How to Fix EV Charger Not Charging?

1. Fixing Charging Connector Latch Mechanism Issues

• Inspect and Clean the Latch Area: Use a flashlight to check for dirt, debris, or obstructions inside the latch or port. Use compressed air or a soft cloth to clean it carefully.
• Check for Damage: Examine the latch for signs of physical damage, such as bent or broken components. If damaged, the connector may need to be replaced.
• Align Properly: Ensure the connector is fully inserted and aligned with the port. Push gently until you hear or feel the latch click into place.
• Test Another Connector: If the problem persists, test the EV with another connector to rule out an issue with the vehicle’s charging port.

2. Fixing Incompatible Connector Issues

• Review your EV’s Manual: Confirm the connector type required.
• Ensure Compatibility: Make sure your connector is compatible with Level 2 EV chargers or DC fast chargers if applicable.
• Test the Connector: Try using the connector with another EV to rule out a manufacturing defect.

3. Fixing Overheated Charger Issues

• Allow the Charger to Cool: Let the charger cool for 20-30 minutes before attempting to use it again.
• Improve Ventilation: Relocate the charger to a shaded area or improve ventilation around it.
• Check for Fault Diagnosis: Refer to the charging station’s user manual for fault diagnosis instructions.

4. Fixing Software Upgrade Issues

• Update the EV’s Software: Check your EV’s dashboard or app for update notifications and follow the manufacturer’s instructions to update the software.
• Update the Charger Firmware: Update the charger’s firmware using its mobile app or control panel and restart both the EV and charger.
• Consult a Technician: For persistent issues, consult a technician to resolve charging station software glitches.

What is the Most Common Cause of EV Chargers Not Working?

The main reason why EV chargers fail to work involves circuit breakers tripping because of overload conditions on electrical circuits. Level 2 chargers require electricity consumption within a 30-50 amp range.

The breaker triggers to protect against overheating or electrical dangers when the shared charging circuit crosses its capacity or when high-power devices share the path of current.

A Tesla Model 3 needs approximately 32 amps to reach full charging speed through a Level 2 charger. A circuit featuring a Tesla Model 3 Level 2 charger that connects to high-power devices like washing machines (10 amps) and electric ovens (20 amps) could exceed the total load capacity of the circuit.

The circuit with its 40 amp rating cannot handle the total 62 amp load made up of 32 amps from the Tesla and 10 amps from the washer and 20 amps from the oven.

How to Solve Home Charging Problem DIY?

When dealing with home charging issues, follow these steps to troubleshoot:

Is the Outlet Actually Working?

Check if the outlet’s giving you the right 240V by plugging in something else. If it’s dead, the breaker might’ve tripped.

Is the Charger or Cable Damaged?

Look for any signs of wear on your charger or cable—frays, burns, or bent pins can stop the charge.

Did the Circuit Breaker Trip?

If your charger isn’t working, check and reset the 40-50 amp breaker. Don’t overload the circuit with other devices.

Need a Software Update?

Your charger might need a quick software update—check the app or reset it if it’s acting up.

Is the Voltage Right?

Use a multimeter to make sure the outlet and charger are getting the right 240V. Low voltage means there’s an issue with wiring or the breaker.

How to Tackle EV Charger Overload?

If your EV charger is overloading, follow these practical tips to resolve it:

1. Check Amperage Settings (Adjust Current Draw)

Tesla, along with other EV charging systems, enables users to modify their charging amperage to match the capacity of their residential electrical setup.

Rescaling amperage from 40A to 30A on devices with 40-amp breakers helps distribute power loads evenly so breakers do not trip.

2. Upgrade Your Electrical Panel (100A to 200A)

The frequent overloads you experience might stem from an inadequate electrical system capacity in your home. A change from a 100-amp panel to a 200-amp panel stands as the primary solution for upgrading electrical systems.

Your home’s auto-adjusted power draw recalculates the amount of power each device receives in proportion to your home’s current total power consumption.

3. Install a Load Management System (Smart Grid Technology)

Present-day EV chargers have integrated load management capabilities as part of their features. The system analyzes your home’s total power usage and distributes electricity between appliances to prevent overload situations.

Your electrical panel risks becoming overloaded when charging multiple EVs concurrently, but installing these systems protects the charger from reaching dangerous levels.

4. Schedule Off-Peak Charging (Demand Response Programs)

Smart chargers let users program their charging to occur when there is low demand, typically during off-peak hours such as midnight to 6 a.m. These hours usually experience 30-50% lower electrical demand compared to peak times.

By scheduling electric car charging during these periods, you can reduce your home’s electrical grid load and prevent circuit overloading. Additionally, many utility companies offer demand response programs that provide charge rate reductions of up to 20% during these low-demand periods.

Utility companies provide their customers with demand response programs that offer charge rate reductions during low-demand periods.

How to Prevent EV Not Charging?

Maintaining your EV charger can help prevent these issues from occurring in the first place.

Keep Your Charging Port Clean

Regularly inspect the port and connector for dirt or damage. Keeping them clean helps maintain a solid connection and prevents charging interruptions.

Monitor for Error Codes

Familiarize yourself with EV home charger error codes and their solutions. This will help you quickly diagnose issues and take action before they become bigger problems.

Schedule Regular Updates

Avoid glitches by keeping both your EV and charger software up to date. Regular updates ensure you benefit from the latest features and fixes.

Perform Routine Inspections

Regularly check your EVSE (Electric Vehicle Supply Equipment) for wear and tear. This can help you identify issues like a damaged charging cable, preventing future charging problems.

FAQs

Why Is My EV Not Charging After a Full Night?

If your EV didn’t charge overnight, it could be due to issues like an improperly connected charger, a tripped circuit breaker, or a malfunctioning charging port.

How Can I Tell If My EV Charger Is Broken?
