Introduction

Welcome to the electric revolution! As more Indians switch to electric vehicles (EVs) to save money and protect our environment, understanding the basic parts of your electric vehicle becomes important. Unlike traditional cars with engines, fuel systems, and exhaust pipes, EVs work differently. They have unique components that need proper care.

At EV Parts India, based in Kerala, we’ve seen many customers confused about what parts their electric vehicles have and what might need replacement. This guide will explain the main components of EVs in simple terms. Whether you drive a Tata Nexon EV, Mahindra XUV400, or another electric model, this information will help you maintain your vehicle better and save money in the long run.

Quick Answers to Your Most Important Questions

Q: Which EV parts need replacement most often?
 A: Battery modules, brake pads, tires, cabin filters, and wiper blades need replacement most frequently.

Q: How long do EV batteries typically last before needing replacement?
 A: Most EV batteries last 8-10 years or 160,000-200,000 kilometers before capacity drops below 70% and replacement becomes necessary.

Q: Are EV spare parts more expensive than regular car parts?
 A: Some specialized components like battery modules and motor controllers are more expensive, but many parts (wipers, lights, cabin filters) cost the same as regular cars.

Q: Can I get spare parts for all EV brands in India?
 A: Yes, at EV Parts India we stock components for all major EV brands available in the Indian market including Tata, Mahindra, MG, Hyundai, and more.

Battery System: The Heart of Your EV

Main Battery Pack

The battery pack is the most expensive and important part of any electric vehicle. Think of it as both the engine and fuel tank combined. Most EVs in India use lithium-ion battery packs that consist of:

• Battery Modules– Smaller sections of batteries grouped together
• Battery Management System (BMS)– The computer that monitors battery health
• Cooling System– Keeps the battery at safe temperatures
• High-Voltage Connections– Special cables that handle the high power

Maintenance Tip: While the full battery pack rarely needs replacement before 8-10 years, individual modules might need replacement if damaged. At EV Parts India, we offer genuine replacement modules for all major EV brands at competitive prices.

12V Auxiliary Battery

Just like regular cars, EVs also have a small 12V battery that powers lights, infotainment systems, and other electronics when the main battery is off.

Replacement Frequency: Usually every 3-5 years, similar to conventional cars.

Electric Motors: The Power Source

Electric motors are much simpler than traditional engines, with fewer moving parts. Most EVs have:

• Main Drive Motor(s)– Converts electricity to movement
• Motor Controller/Inverter– Controls power and speed
• Reduction Gear– Similar to a simple gearbox

Did You Know? Electric motors require almost no maintenance and can last the lifetime of the vehicle. However, motor controllers sometimes need replacement after 5-7 years of use.

Charging Components

Proper charging is essential for all EVs. These parts make charging possible:

• Onboard Charger– Converts AC power from your home to DC for the battery
• Charge Port– Where you plug in your charging cable
• Charging Cable– Connects your car to charging stations

Common Issue: The charging port flap mechanism or the port pins themselves can wear out with regular use. We stock replacement charging ports for all Indian EV models.

Brake System: Different from Regular Cars

Electric vehicles use two types of braking:

• Regenerative Braking– Uses the motor to slow down while generating electricity
• Mechanical Brakes– Traditional brake pads and discs for stronger stopping

Important Note: Because EVs use regenerative braking often, mechanical brake pads actually last longer than in petrol cars. However, due to less use, brake parts can sometimes develop rust or stiffness.

Thermal Management System

Keeping batteries at the right temperature is crucial for EVs:

• Cooling Pumps– Circulate coolant through the battery
• Radiators/Heat Exchangers– Release heat from the system
• Temperature Sensors– Monitor system heat

Replacement Part Alert: Cooling pumps are one of the more common failure points in EVs after 5+ years. At EV Parts India, we’ve seen increased demand for replacement cooling system parts in 2025.

Electronic Control Units (ECUs)

Modern EVs contain multiple computers that control different systems:

• Vehicle Control Unit (VCU)– The main computer
• Battery Management System– Monitors battery health
• Motor Controller– Manages power delivery
• Infotainment System– Handles entertainment and information

Tech Tip: Software updates can sometimes fix problems without replacing parts. Always check if an update is available before replacing electronic components.

Common Wear Items All EV Owners Should Stock

These parts need regular replacement regardless of whether you drive an electric or petrol vehicle:

• Wiper Blades– Replace every 6-12 months
• Cabin Air Filter– Replace yearly for clean air
• Tires– EV tires wear faster due to higher torque
• Suspension Components– Bushings, shock absorbers
• Lights– Headlights, indicators, brake lights

EV-Specific Components Available at EV Parts India

Our online store stocks all these specialized EV components:

1. Battery Modules– For all major EV brands in India
2. Charging Ports and Cables– OEM-grade replacements
3. Cooling System Parts– Pumps, radiators, and hoses

5. BMS Components– Sensors and control boards
6. High-Voltage Safety Equipment– For DIY enthusiasts

How to Check If Your EV Needs New Parts

Watch for these warning signs:

1. Reduced Driving Range– Might indicate battery module issues
2. Charging Problems– Often related to the charging port or onboard charger
3. Warning Lights– Always check the manual if warning lights appear
4. Unusual Noises– May indicate motor or reduction gear problems
5. Battery Heating– Could mean cooling system problems

Case Study: Tata Nexon EV Owner in Kerala

Sanjay from Kochi noticed his 2022 Nexon EV wasn’t charging properly at public chargers, though home charging worked fine. After checking online, he suspected a damaged charging port. He ordered a replacement charging port assembly from EV Parts India, and after a simple 30-minute installation at his local garage, the problem was completely solved, saving him thousands over dealership repair costs.

DIY vs. Professional Repair for EVs

While some parts can be replaced at home, others require professional help:

Safe for DIY:

• Wiper blades
• Cabin filters
• Light bulbs
• 12V battery

Professional Help Needed:

• High-voltage battery work
• Motor controller replacement
• Cooling system repairs
• BMS servicing

Safety Warning: Never attempt to open or repair the main high-voltage battery pack without proper training and equipment. This can be extremely dangerous.

How to Purchase Quality EV Parts

When buying spare parts for your electric vehicle, remember these tips:

1. Check Compatibility– EV parts are often model-specific
2. Verify Warranty– All parts from EV Parts India come with a warranty
3. Look for BIS Certification– Ensures quality and safety standards
4. Compare Prices– But be wary of suspiciously cheap parts

The Future of EV Components in India

As we look ahead to late 2025 and beyond, we’re seeing exciting trends in EV parts:

• Standardized Battery Modules– Making replacements easier and cheaper
• Longer-Lasting Components– New materials improving durability
• More Repairable Designs– Reducing waste and repair costs
• Local Manufacturing– Reducing prices through “Make in India” initiatives
