Сделай сам "Теслу" из старого автомобиля!

В этой книге исследуются возможности и проблемы электрического преобразования существующего (подержанного) автомобиля с двигателем внутреннего сгорания в качестве альтернативы покупке нового электромобиля. Переоборудование подразумевается как проект "сделай сам", который может быть осуществлен любым человеком, способным освоить все необходимые навыки и обладающим достаточными средствами для приобретения автомобиля в первую очередь. Части или весь проект может быть передан на аутсорсинг в механические мастерские или подобные организации, если есть области, где знаний или оборудования самодельщика недостаточно.

The world is facing the crisis of oil and the price of is oil is hiking day by day. Even though the fossil oil is used in vehicles, it emits the most pollutant chemicals like Sulphur dioxide, carbon monoxide, nitrous oxide etc. which is hazardous to human health and environment. But today, even though many alternatives form of vehicle has been arrived in the market but the ratio of IC engine vehicle to the eco-friendly vehicle is still high. Considering the bad consequences of IC engine vehicle and hike in gasoline products, many automobile companies have been progressively working on the design, development and production of alternative ecofriendly electric vehicles.

Converting cars also helps in the transition to a more circular economy; instead of relying on the consumption of finite resources to produce new products, the lifespan of existing products is extended as much as possible. Products are shared, repaired, reused, remanufactured, and lastly recycled. This project represents an example of the remanufacturing step of a circular economy. Instead of disposing of outdated cars with internal combustion engines and then producing new electrically powered vehicles, this project makes use of the existing car fleet and extends its lifetime.

The electrification of personal transport vehicles is one of the strategies to counteract global warming and dependence on fossil fuels. Diesel-powered cars are already prohibited in several big cities, and the prices for fuel are constantly climbing. Even so, electric cars are still a premium that not everyone can afford as they could an older ICE car. This means that there can be a gap in the near future where the French working and middle class can neither afford a new EV nor refuel their combustion engine car.

This book investigates the possibilities and challenges of electric conversion of an existing (used) combustion engine car as an alternative to buying a new electric car. The conversion is meant to be a DIY project that can be carried out by anyone with the capacity to learn all the skills necessary and with sufficient funds to own a car in the first place. Parts of or the whole project can be outsourced to machine shops or similar if there are areas where the knowledge or equipment of the builder is insufficient.

This type of conversion proves to be highly modular, where the selection of both car and components depends on budget, time, and knowledge. Brushed DC motors offer reliability at a low cost but with relatively low efficiency. A three-phase induction motor will be a more costly option but with the benefit of higher efficiency and power. The batteries that are deemed appropriate for the conversion are lead-acid and lithium-ion batteries. Lead-acid batteries are robust and have a low cost. However, their low energy density will result in a higher weight, making this type of battery best suited for a small car with short range. Lithium-ion batteries, which are used in commercial EVs, have a high energy density and lower weight. They come at a high cost, however, and they require individual monitoring of the cells' voltage to prevent potential failure.

The converted car will have to be registered as a modified vehicle in order to legally be used. The original total weight of the car cannot be exceeded during the conversion, and because of this, a car with low curb weight and high max load is preferable as a starting point.

The purpose of this book is to research the possibilities and challenges regarding the electric conversion of used cars for personal day-to-day use.
