Petrol prices have increased tremendously in the last one year. People have started looking for alternate options to tackle the rising fuel prices and as a result people are now considering electric cars too. There are manufacturers like Tata, MG and Mahindra who have electric vehicles in the market. There are even more brands in the electric two-wheeler segment. There are many people who are working on new ways to convert a regular petrol car into an electric vehicle and here we have one such video where a man has successfully managed to convert his Hyundai Santro hatchback into electric car in 3 days.
The vidoe has been uploaded by Making With Mihir on their YouTube channel. In this video, the person talks about a Hyundai Santro that originally belonged to his grandfather. He converted the Hyundai Santro into an electric car in three days. The video mentions all the changes that he had to make to convert this petrol hatchback into an electric car. He calls it a strangest yet simplest way to convert an ICE car to an electric car. In this video, he starts by showing a small scale model of an internal combustion engine.

It shows how the engine powers the power steering and AC compressor and by removing the engine completely for EV conversion, he would require more motors to power the steering and the AC. This would lead to more complications and wiring which would make the engine bay look not very neat. So he removed half of the engine and left the pistons in. He fabricated a mount which is placed over the cylinders with an electric motor installed on it. This new electric motor works well with the overall existing AC and power steering set up.
As he was doing this conversion for the first time, he took help from mechanic and completely took the engine out to work on it. He mentions in the vidoe that if anyone wants to do it on their car, they don’t have to take the engine out completely and it can be done without any difficulties. The car now uses a 6kW, 72V BLDC motor connected to a 350A Kelly Controller. The battery is placed in the boot of the Santro and the charging port is placed at the place where the regular fuel was filled. The fuel tank has been completely remove from the car as it does not require it anymore.
It uses a 72V 100Ah Lithium Ferrophosphate battery. He had to make some changes to improve the braking in this car. An electric brake booster vaccum pump was installed along with a 72-12V DC-DC convertor to bring the 72V from the LFP battery in the back down to 12V to charge the lead acid battery to power the central locks, power windows, and the lights. The Santro currently uses a very small battery and low power electric motor. It currently has a top-speed of 60 kmph and an driving range of 80-90 kms which is sufficient for the city use. The overall cost of this conversion is around Rs 2.4 lakh and the running cost of this Santro EV is Rs 1 per km.
