Regular maintenance plays a key role in preventing electrical system failures:

Inverter coolant replacement: Every 40,000–60,000 km, the coolant in the inverter system should be replaced to prevent overheating.
Check hybrid battery health: Perform periodic checks on the hybrid battery to ensure it is holding charge and functioning properly.
Inspect electrical connections: Ensure all connections are tight and free from corrosion to prevent power losses.
12V battery health: Regularly test the 12V battery and replace it when it shows signs of deterioration.
Cooling system inspection: Ensure that the inverter’s cooling system is functioning and the radiator fans are clean.
