One of the quiet assumptions of going electric is that rats will lose interest. No hot engine, no oily bay, no problem. It's a nice idea — and it's wrong. EV owners across India are finding chewed wiring too. Here's why, and how to protect an electric car safely.
Why rats still go for EVs
Warmth is only one reason rats move into cars. The bigger ones are shelter and something to chew. A parked EV is a quiet, dark, protected space — and it still carries a lot of low-voltage wiring, connectors and soft insulation. Rats gnaw constantly because their front teeth never stop growing, so a sheltered spot full of wiring is enough.
What gets damaged
- Low-voltage wiring harnesses — the 12V system that runs lights, locks, sensors and the infotainment.
- Sensor wiring — EVs rely on many sensors, and chewed leads trigger warnings and diagnostics.
- Cabin air-filter area — a favourite nesting spot, EV or not.
- Rubber seals and coolant lines — EVs still have cooling systems for the battery and motor.
The one rule every EV owner must follow
Your EV has a high-voltage system, marked with orange cables, running from the battery pack. Never mount anything on it, never place anything against it, and never tap into it for power. Any rat deterrent should run on its own battery or USB power and sit in the front compartment, away from high-voltage components.
Protecting your EV
- Park clean — away from garbage, drains and food stalls.
- Check regularly — droppings, nesting material, a musky smell.
- Keep food out of the cabin — especially on long parks.
- Add an independent deterrent — powered on its own, mounted away from HV parts.
The EchoRepel Car Rat Repellent runs on AA batteries or USB, so it never touches your EV's electrical system. For model-specific advice, see our guides for the Tata Nexon, Tata Punch and Hyundai Creta, all sold in electric versions.
