4. Charging Slower than Expected

Symptoms:

• Charge time takes longer than listed.
• Battery percentage increases slowly.

Potential Causes and Solutions:

• Charger Compatibility: Ensure your EV charger is compatible with your vehicle. Different models have varying charge rates; using a lower-rated charger may lead to slower charging.
• Environmental Factors: Extreme temperatures can affect charging speed. Avoid charging in very cold or very hot conditions whenever possible.
