This section of the EVES website provides information on frequent questions and areas of interest for our audience.

How much does it cost to convert a car to electric?

It all depends on your requirements. Starting from EUR 30,000 for a very basic conversion, all the way up to EUR 75,000-100,000 if you would like high tech with excellent performance.

Can you convert a vintage car to electric?

Yes, older vehicles is preferred due to “MOT/Registration” issues. In a nutshell, it can be a nightmare to convert a vehicle manufactured after 1996 due to the comprehensive EU type approval regulations.

Can any vehicle be converted?

Basically, yes! However, it’s preferable to start out with a vehicle that is in good condition in order to keep costs to a minimum.

What is the top speed of EVs?

It depends on a couple of things, such as system voltage and transmission. Lower system voltage equals slower top speed as the motor will run out of juice further down in the rev band.

How far can I drive between charges?

It depends on the size of the traction battery. The more batteries you can squeeze into the vehicle, the further you will be able to drive between charges. More kWh of energy will give you a longer range.

What kind of systems do you install in your conversions?

Anything from cheaper 84 VDC systems, all the way up to state-of-the-art high performance 400 VDC systems. It all depends on the customer’s dream and budget.

What kind of batteries do you use?

For most systems with lower voltage and low power demands (about 50-100 kW), we always use LiFePO4 (Lithium Iron Phosphate) since it is a very safe and reliable chemistry. These cells never tend to catch fire in the event of an accident or short-circuit. For systems that demand higher voltage and power, we use Li-ion NMC (Nickel-Manganese-Cobalt) due to their higher nominal voltage of about 3.65 VDC and higher discharge rates than LiFePO4.

How long does it take to recharge?

This is related to the type of charger that is installed. In general, we use chargers with power between 1.8 kW one phase to 10 kW three phase. This means you will need approximately three hours of charging with a 10 kW charger and a battery capacity of 30 kWh.

How long will the batteries last?

If the state of charge is kept between 10-90%, they will last approximately 2,000 charge cycles with only a degradation of around 15-20% capacity. This means if you reached 150 km with your 20 kWh battery capacity when the battery was new, you will reach about 125 km after 2,000 charge cycles.

What level of service will my EV require?

A modern AC drive system requires almost no service at all. A system with liquid cooling will need to have the coolant changed every other year or so. Then, of course, all the other systems of your vehicle, such as the brake system and transmission, will require a normal service.

How long does a conversion take?

It’s very hard to say. A new system that requires a lot of preparation and engineering hours will take 3-5 times longer (sometimes even 10 times longer depending on the development needed) than converting a vehicle that already has a “plug and play” system available.

How much do EVs cost to run?

Once the vehicle has been converted and paid for, the running costs are very low compared with a normal ICE (Internal Combustion Engine) vehicle. If you have the possibility of charging at home or at work you will be in for a treat.

Can you use an automatic gearbox in a conversion?

This is not something we have ever undertaken ourselves, but we have seen this in other conversions so the answer would be yes, it is possible.

Do EVs have air-conditioning?

If you want air-conditioning, you can have air-conditioning. It is possible to mechanically run an A/C compressor from the output shaft of some motors. Electrically driven compressors are also available.

Do EVs have power steering?

Generally speaking, yes. It may be less common on really old vehicles that are being converted, but it’s definitely possible to retrofit.

Do EV conversions have regenerative braking?

This function is available at various levels of refinement in most of the motor controllers we use.

Who will service my car?

If you order a “turnkey” project where EVES AB builds the entire system, we can also service your vehicle. We can also service and run diagnostics on other special/converted vehicles.

What kind of warranties do you offer?

Various components have different warranties, in general from 12-24 months from date of purchase. EVES AB will cover any issues concerning the installation of the system for 24 months from receiving final payment.

What about insurance?

Ask your insurance company for an independent valuation of your vehicle. Then it should be no problem at all to have your vehicle fully insured.

Does EVES AB offer EV conversion kits?

At present, we can offer conversion kits for a few different vehicles. We are always interested in new projects, so don’t hesitate to contact us with your request.
