KATHMANDU: Many people may not know what to do to keep their electric car in good shape after a long trip. EVs are a new technology worldwide, so not everyone understands every aspect of them yet.
Nepal’s hilly roads, steep climbs and descents, potholes, gravel and muddy tracks can put stress on different parts of a vehicle. A basic inspection and any needed repairs before you start using the car again will save you money later and keep you safe.
The battery is the most expensive part of an EV, so it’s wise to check its safety, along with the tires, brakes and suspension, before you return to regular use. Other things to pay attention to are covered below.
- Check tire condition and pressure
Tires should be the first thing you inspect after a long trip. Look for unusual wear, cracks, cuts or bulges. If a stone or nail is stuck in a tire, have it removed and repaired, then set the tire pressure correctly.
- Inspect the braking system
EVs use regenerative braking, so the mechanical brakes are used less than in regular cars. Still, long descents and constant braking can affect the brake pads and discs, so it’s good to check them. If you hear noise when braking, feel vibration, or notice weaker braking, get a mechanic to look at it.
- Check the underbody
If you’ve driven on rough mountain roads and feel the bottom of the car may have hit something, have the underbody checked. Look for signs of impact, dents or fluid leaks.
- Check the suspension and steering
Potholes and gravel roads on a long trip can strain the suspension. If you notice oil leaking from the shock absorbers, hear noise when turning the steering wheel, or feel the car pulling to one side, have a skilled technician inspect it.
- Clean the cooling system
The cooling system plays an important role in keeping the battery, motor and power electronics at the right temperature. After a long trip, dust and dirt may build up in the air intake, radiator and heat exchanger. Clean them and check the coolant as well.
- Inspect the charging port
You probably used DC chargers at various places during the trip. Check whether dust, water or dirt has gotten into the charging port. If the cable or connector is cracked, burnt or unusually hot, stop charging immediately.
- Pay attention to battery charging
After returning from the trip, it’s best to charge the high-voltage battery fully, at your own pace.
- Clean the car thoroughly
A long trip leaves the body, interior and underbody dirty, so give the car a good cleaning. Also clean the wheel arches, cameras, sensors and windshield.
- Check the dashboard warning signs
See whether any warning is showing for the battery management system, motor controller or other electronic systems. If a warning appears, take the car to a service center for a diagnostic scan.
- Check the 12-volt battery
Besides the main battery, an EV also has a 12-volt auxiliary battery. Check its condition, and also check the headlights, indicators, brake lights, wipers, air conditioning and cabin air filter.
