Here's few tips before you start an electric conversion project

At Ingenext, we know all about EV conversions! We've done a bit of everything, from classic cars to vans, baggage tractors and a Beetle. We've learned a lot in the process, which is why we're now considered experts in the field. 

Here are a few things to think about before embarking on your electric conversion project. 

What Is an EV Conversion and Why Do It?

Electric vehicle (EV) conversion involves replacing a vehicle’s internal combustion engine with an electric drivetrain. This process transforms a gas-powered car into a cleaner, more sustainable vehicle. For many enthusiasts, it’s an opportunity to preserve a classic car, reduce emissions, or simply enjoy the thrill of a modern electric motor. Beyond environmental benefits, EV conversions can lower long-term costs by reducing fuel and maintenance expenses. Whether you're an eco-conscious driver or a DIY gearhead, converting a vehicle to electric power is a rewarding challenge with significant upside.

EV Conversion Cost Breakdown (Canada)

Before jumping into an EV conversion project, it’s crucial to understand the associated costs. In Canada, a basic conversion typically starts at $15,000 CAD but can reach $25,000 or more depending on the parts, vehicle type, and whether you outsource labor. The battery is usually the most expensive component, followed by the motor and controller. While some try to cut costs by sourcing used components, reliability and compatibility can become issues. Proper budgeting will help you avoid unpleasant surprises down the line.

Good planning is the key to success!

First of all, we advise you to draw up a budget. Depending on your needs and the components you choose, a conversion project will cost a minimum of around $15,000 CAD. And don't forget  to allow time, as you'll be putting in many hours of work. 

Secondly, we strongly suggest that you check the laws and regulations governing electrical conversions where you live. In Quebec, for example, it's highly regulated, and you need to produce a detailed report signed by an engineer in order to get a license plate. That's enough to put some people off! It would be a shame to run into this problem at the end of your project. 

Thirdly, choose your components wisely. Are you going to buy separate components? A donor vehicle? Do you want a vehicle with a long range? Power? Be careful where you buy your components, and make sure they're reliable. We've often found that when starting up controllers for our customers, many had bought batteries with cells that were unbalanced and unusable.

If you need to replace your battery, your budget will literally explode. The batteries and motors we sell with our controllers are tested before shipping, so you can be sure that your main components are reliable. 

Choosing the Right Vehicle for Conversion

Not all vehicles are equally suited for EV conversion. Ideally, you’ll want a lightweight car with enough space to accommodate batteries and electrical components. Classic cars, small sedans, and compact pickups are often chosen due to their simple mechanical layouts and nostalgic appeal. Vans and utility vehicles can also be great candidates, especially for commercial or family use. However, be aware that heavier vehicles require more powerful motors and larger batteries, increasing your overall cost and complexity.

New vs. Used Components: What to Consider

One of the first decisions you’ll face is whether to buy new or used components. Used parts, like batteries and motors from salvaged EVs, can significantly reduce upfront costs. However, they carry risks—batteries may be unbalanced or degraded, and controllers could be incompatible with your system. At Ingenext, we often see DIYers struggle with faulty or mismatched parts. That’s why we test all Tesla components we sell, ensuring safety, performance, and peace of mind for our customers.

Tesla EV Components: Why They’re a Smart Choice

Tesla parts are increasingly popular for EV conversions due to their reliability, performance, and widespread availability. Tesla motors offer exceptional torque and efficiency, while their batteries provide long range and durability. At Ingenext, we’ve developed plug-and-play controllers for Tesla Model 3/Y and Model S Plaid (2021+) components, making integration simpler than ever. Whether you're looking for power, range, or both, Tesla parts paired with our tested systems give you a solid foundation for your project.

 

Understanding the Technical Skills Needed

Converting a vehicle to electric power isn’t plug-and-play—it requires a mix of mechanical, electrical, and software knowledge. Familiarity with CAN BUS systems is essential for diagnostics, firmware updates, and configuring your components. Basic skills in wiring, soldering, and vehicle mechanics are also important. For safety, we highly recommend taking a high-voltage training course. Working with lithium-ion batteries can be dangerous if mishandled, so never underestimate the importance of preparation and education.

 

Legal and Certification Requirements in Canada

Every province in Canada has its own set of rules for EV conversions. In Quebec, for example, a converted vehicle must pass a detailed inspection and be certified by an engineer to obtain a registration. This process involves documentation, safety validation, and in some cases, emissions exemption testing. Ignoring legal requirements can delay or derail your project. We recommend researching your local laws early in the process and consulting with an engineer familiar with EV standards.

Safety and basic knowledge

Our aim here is not to scare you, but to make you aware that batteries can be lethal. No one is immune to mishandling, which can lead to electric shock. Our advice is to take a high-voltage training course to make sure you're well informed. 

We also recommend that you have a good knowledge of CAN BUS, so that you can perform diagnostics and configuration yourself. Of course, mechanical knowledge will certainly help you to complete your project successfully. Bear in mind that a battery takes up space and can affect the vehicle's weight and stability. 

 

Common Mistakes to Avoid in Your EV Conversion

Many conversion projects fail due to poor planning or avoidable errors. Common pitfalls include underestimating costs, buying incompatible parts, skipping safety training, and neglecting legal requirements. One critical mistake is improper battery placement, which can affect the vehicle’s weight distribution and stability. Another is overlooking cooling systems for batteries and controllers. Learning from others' mistakes—and asking experts for guidance—can save you time, money, and frustration.
