By converting your car to electric, you'll not only be
helping the environment but you'll also save money!

Your vehicle will run on ZERO EMISSIONS, and will never pollute our environment.

  • NO OIL CHANGES
  • NO SPARK PLUGS
  • NO EXHAUST LEAKS
  • NO EGR VALVES
  • NO COILS
  • NO COOLANT FLUSHES
  • NO EXPENSIVE ENGINE REPAIRS
  • NO ENGINE SENSORS
  • NO CARBON BUILD-UP
  • NO GAS TANK

Electric cars are 100% zero emission at the tail pipe, they create NO harmful gasses, this makes them infinitely cleaner & better for the environment compared to internal combustion engine vehicles.

The gasoline/petrol/diesel engine is the least efficient mechanical device on the planet and single most pollution producer for major cities across the globe.

Contrary to what oil companies want you to believe, Lithium Iron Phosphate batteries do not harm the environment, as Lithium is plentiful. It is found in our Oceans, and found below the surface of desert areas, which were once oceans; this is where the lithium has been concentrated by solar evaporation. The largest known deposits of lithium are in Bolivia and Chile.

Electric cars use electricity that can be produced from environmentally friendly renewable sources such as wind, solar, hydro, geothermal sources, without the use of nuclear, coal or oil.

When you drive a Rexnamo Car Conversion you're recycling your existing vehicle, giving it a new life, in the form of a cleaner more efficient green machine.

In gas cars which are 17% efficient, most of the gasoline is not used up and exits the tail pipe, literally money going up in smoke. An electric motor on the other hand is approximately 95% efficient; it has been used for over 100 years in industry. Electric motors are found around the home, and is the GREENER SOLUTION to our environmental & health problems.

Health effects

The effects of particular matter on health occur at levels of exposure currently being experienced by most urban and rural populations in both developed and developing countries. Chronic exposure to particles contributes to the risk of developing cardiovascular and respiratory diseases, as well as of lung cancer.

The mortality in cities with high levels of pollution exceeds that observed in relatively cleaner cities by 15–20%. Even in the EU and India, average life expectancy is 8.6 months lower due to exposure to particular matter2.5 produced by human activities.

Key facts:

Air pollution is a major environmental risk to health. By reducing air pollution levels, we can help countries reduce the global burden of disease from respiratory infections, heart disease, and lung cancer.
The lower the levels of air pollution in a city, the better respiratory (both long- and short-term), and cardiovascular health of the population will be.
Indoor air pollution is estimated to cause approximately 2 million premature deaths mostly in developing countries. Almost half of these deaths are due to pneumonia in children under 5 years of age.
Urban outdoor air pollution is estimated to cause 1.3 million deaths worldwide per year. Those living in middle-income countries disproportionately experience this burden.
Exposure to air pollutants is largely beyond the control of individuals and requires action by public authorities at the national, regional and even international levels
The WHO Air quality guidelines represent the most widely agreed and up-to-date assessment of health effects of air pollution, recommending targets for air quality at which the health risks are significantly reduced. The Guidelines indicate that by reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic metre, we can cut air quality related deaths by around 15%.

WHAT CAN WE DO FOR YOU?

Big breakthroughs in battery technology have raised hopes the electric car can transform the auto industry and set us free from fossil fuel dependence.

Some small businesses are determined to make sure the electric revolution is as environmentally friendly as possible. And their vision of the future relies on repackaging the past.

Since manufacturing new cars is energy-intensive and polluting, these specialists believe transforming old, petrol-guzzling cars into clean, green electric vehicles can play an important part in reducing carbon emissions.

Retro-electric cars

Ghaziabad-based company Rexnamo Electro Pvt. Ltd. takes the husks of worn-out classic models and gives them a brand new lease of life. The auto shop has sold more than 20 retrofitted electric cars and DIY conversion kits over the past decade.

“The future of transportation is electric, no question,” says Rexnamo Electro's owner Naman Chopra. “So converting old vehicles always seemed like a good idea to us. Why let them go to waste? Essentially it’s a recycling business because you’re taking a car from the scrapyard and giving it a longer life. If you could show auto shops all over the world how to do this work, it could produce a big change.”

Rexnamo sells converted cars for anywhere between £2,800 / ₹2,40,000 and £6,600 / ₹5,70,000. The most commonly-used kit offers restored cars top speeds of 55mph / 88 kmph and a driving range of up to 50 miles / 80 km before it needs to be recharged - which costs around 8,56,680 (before Govt. Subsidies) for a Compact car like Swift, Indica.

Other businesses are hoping to enhance the performance of electric vehicle (EV) conversion cars by using more powerful and expensive lithium batteries, aware most consumers still have “range anxiety” about electric cars and want to be able to drive long distances.

Rexnamo also offers vintage cars like Lancers, Honda City, Contessa, Old BMWs, Volkswagens and Porsches, fully restored and electrified using the latest lithium batteries, from £38,000 / ₹32,79,677. The basic Rexnamo Vehicle retrofit provides a range of 80 to 100 miles (or 130km to 160 km) on a full charge.

“The process of building a new car (by traditional manufacturers) is costly, in terms of energy and greenhouse gas emissions, so we have to take advantage of all those cars that are close to the end of their life, restore and electrify them,” explains Naman Chopra, founder of Rexnamo Electro.

Naman hopes the “sexy” retro design icons can drum up interest among carbon-conscious consumers across India. “EV conversion could definitely play a big role in the ecological transition,” he says.

We believe other kinds of transport could take advantage of EV conversion and make even bigger ecological and economic gains. - Like Buses.

“Where conversion would actually make most sense would be with delivery and commercial vehicles – vans, trucks and buses,” says Naman. “Because they were built and fitted for specialist purposes, there might be enough value left in old vehicles to make it worthwhile converting hundreds or thousands at a time. Some business might feel that would be cost-effective in terms of ongoing running costs.”

“Sustainability is very, very important to us,” says Naman. “By remanufacturing (old) vehicles, we’re saving about 10 tonnes of the raw materials normally used to build a new electric vehicle. It’s also good business. We can deliver a product at much less than the cost of building a new electric vehicle.”

Each remanufactured Rexnamo bus costs about ₹82,80,000  to convert, about₹32,00,000 cheaper than building a new electric bus from scratch.

Shetterly believes there is room for growth in the bus conversion market, considering that India’s transition away from diesel buses could take “another couple of decades at least”.

Back to cars, Naman, an EV conversion expert who estimates that an impressive 30,000 old petrol cars have already been electrified by small businesses and amateurs around the world. A figure he expects to carry on growing.

“Right now we might still only be in the tinkers and innovators stage of the electric car. So EV conversion people remain important as apostles and flag-wavers. We take the mystery out of it. People distrust advertising, so we have a role to play in changing perception, mostly by appealing to car nuts who remember an old favourite, or an object of desire from their youth.

“We’re able to show those people what the electric car is capable of. It’s fun to watch people change how they think about it.”

Rexnamo’s experience with individual approval or homologation of the EV conversion in India and EU countries.

The Big question
The biggest question for most of our customers is whether they can get their EV conversion road legal and E-licensed after conversion. Normally, in every EU country the ECE R100 standard is applicable for:

– any EV, and
– vehicle category M+N and
– a topspeed over 25 km/hr.

So, most likely, also your conversion. Also, every local institute for road safety will have their own checkpoints to make the testprocess for homologation complete.

Some institutes will check whether controller, motor, converter, charger, etc. are EMC compliant (electro magnetic radiation), which means that just CE-marking might not be enough as an automotive standard, but E-marking is what they will check. This is concerning:

Electro Magnetic Compatibilty acc. to Automotive Directives 2004/104/CE AND 2009/19/CE.

In this document we will try to explain, as much as possible, what aspects could be important for your conversion. It is meant to be purely informative, based on our experiences, and that of our customers.

In every situation it is the best approach to involve your local institute upfront, and not confront them afterwards with your creation. It is likely that you’ll experience a lot of goodwill with the inspectors because they will like your project, but be sure what they will check.

‘Deal-breakers’
In some countries it is not possible to make a vehicle heavier, and still be licensed as a 4, 5 or more person vehicle. Check upfront how the inspector deals with this issue. This also depends on the ‘age’ of the vehicle.

Although we have not heard of this situation yet, it could be possible that an institute demands that the total vehicle should be tested for EMC, and not just the single parts. That could complicate the homologation considerably. The only option is that you try another country for homologation, get it E-licensed there, and import the car again into your own country.

Inspiring Projects

Here are some top 9 Factors that determine your EV conversion budget.

When you have plans to convert your car or boat to electric, one of the first questions that will pop your mind is: What budget will I need? Well, anything between Rs. 3,50,000 and Rs. 80 Lacs is realistic. That’s not much of an answer. Here are the 9 major factors that determine your EV Conversion budget.

1. DIY vs professional workshop
If you are kind of smart, have the time and want to save some money: go for Do It Yourself, buy the battery, motors, motor adaptor plate, charger and controller from Rexnamo Ghaziabad. If you have the budget and want your project to be ready ASAP: go for the professional workshop situated at Rexnamo Ghaziabad.

2. The type of vehicle
You can imagine there is a big difference between converting a heavy modern car like a 2014 Mercedes S Class and a Tata Nano. The Mercedes has a lot of complex computerized systems, so you will need a solution to work with the computers and secondary functions like airconditioning, power steering, etc. The Merc is also very heavy; over 2000kg. The Nano is just plain simple and lightweight: under a 1000kg. It needs half the batteries.

3. Sporty vs economy
Is it allright that your car does 0-100km in over 10 seconds or do you want the Tesla way and count to three? Does top speed matter to you? Max 100km/hr is totally different from a maximum speed of 200km/hr. You will need a different motor/controller setup, maybe even two electric motors.

4. Regenerative breaking
Do you need regen? Overall you can win 10% of battery capacity with regenerative breaking. But that’s only when you drive in a surrounding where you have to break every once and a while: a city environment. So if you do more stretches outside the city, you might not benefit from it at all. If you want regen you go for an AC (or brushless DC) drivetrain. In general AC is about 30% more expensive than brushed DC.

5. Range
It’s easy to think of an electric car going more than 200km on just one charge. But do you really need it? Because this has a serious impact on your budget. In a small like a Maruti Swift, a 70km range will cost you Rs. 151293 in lead-acid batteries. 120km range will cost you Rs. 4,91,603 in lithium and >200km will cost about Rs.9,07,760. With the amount of batteries rising, the cost for casing, cables and your BMS(battery management system) will also rise.

6. Is it done before? 
Sometimes standard parts like a motor mount and battery casing are already available for specific models from Rexnamo, so you can just order them from us. If you are the first to convert a specific type of car, you might need to hire an engineer for these parts. Furthermore, the company needs to mill just 1 piece, so the cost cost will be significantly higher. Last but not least: getting a unique car approved by your local RTO could be a lot more expensive than a car that has been approved before.

7. Bargains
Now and then cheap lithium batteries, as a result of bankruptcy’s or damaged cars, are dumped on the market. These can be a nice push to launch your project. Disadvantage is that there is no warranty on these batteries. Back-up and information should not be a problem when you visit internet blogs about these type of batteries.

8. Basic vs complex battery management
If you keep your BMS simple, like a basic battery balancer with a basic State of Charge meter, you can save money. You will have to keep an eye on your batteries every now and then and be more conservative with charging and de-charging. But if you like better protection and a lot less looking around, and a fancy State of Charge meter on your dashboard, you will end up spending Rs. 189,000 more on your conversion.

9. Charging
Last but certainly not least: when you use one 2500W charger on a small battery pack like 17kWh, it will be full in 6-7 hours. If you would like to charge with 22kWh, a 22kW AC charger will do the job in less then an hour. It will cost you Rs. 340,340 more though.

Conclusion
The budget you need for your electric car conversion depends on your wishes. If you want a rock bottom conversion, your best option is to buy some second hand kit and lead acid batteries and put it in a small city car. You will have a nice drive around the village. Ranges over 200km will certainly do Rs 19,00,000 in components.  If you want a Tesla killer reserve a Rs. 75 lacs and call us for help 🙂

Little Generator Trailer Lets Electric Cars Go the Distance

When someone decides to make the leap from a gas-powered car to an electric one, they know that they are giving up some of the conveniences of their previous vehicle. With EV charging stations still not available everywhere, trips have to be planned carefully and the EV owner has to calculate exactly how much power they will need to get there and back.

The table below describes the typical cost of an electric car conversion based on vehicle type.
