Hybrid with your own hands

The benefits of hybrid cars are too attractive to not be interested in home-grown designers, inventors and other makers, as well as small businesses. As a result, the world has received a lot of vehicles that have become hybrid not on the conveyor, but after several (or several dozen) years after their release.


The idea of ​​self-creation of vehicles with a combined power / drive system is quite real, it is proved in practice. Usually, the process begins with the search for a "donor", since few people are able to execute such a project from scratch. And then everything depends on the chosen scheme, components, level of knowledge and skills of the artist.


Popular schemes for creating a hybrid car with their own hands


There are two common ways of converting a single-fuel car into a hybrid, each with its own variants of execution.


Hybrid with your own hands -1


Hybrid electric car


The electric vehicle is best suited for conversion into a hybrid. First, it has almost all the filling stuff, and secondly, the interaction between the elements is designed and adjusted by specialists. But relatively easy to implement is only one option.


  • Installing a gasoline generator.

The type of hybrid car, which can be obtained as a result, is called the Range-Extended Electric Vehicle (EREV) in the world or an extended-range electric vehicle. Its essence is to use a low-power internal combustion engine only as a generator. In the same way, specialists from Bavaria turned their BMW i3 into a hybrid. The whole essence of self-processing is to buy a household gasoline generator, to safely install it in a car and to coordinate its work with the native "brain" of the car.


  • Installation of a drive motor vehicle

The idea of ​​installing an internal combustion engine in an electric car - from a number of crazy ones. Theoretically, it can be implemented, but very complex. In addition, the vehicle after such a modification, most likely, will significantly lose functionality. That is why there are units of such projects around the world.

Hybrid from a gasoline or diesel car


The idea of ​​converting a gasoline car into a hybrid is much more popular. This is due to the relative compactness of the electric drive and the ability to place traction batteries in any convenient location. Each such project requires the installation of additional batteries, so the options depend only on the type and location of the electric motor.


  • Installing motor-wheels or classical electric drive on a free (driven) wheelbase

Performing an electric rear drive is technically simpler than the front. The use of motor-wheels does not require interference in the suspension, but it heavily loads. The classic scheme of a permanently installed motor with a drive through the semi-axis requires the refinement or replacement of the entire bridge, but does not impair the controllability and, in addition, does not load the suspension.

  • Installation of the auxiliary engine on the flywheel of the ICE

The development of this technology began with the idea of ​​improving the dynamic performance of the car without further engine propulsion. This was achieved by installing a modified, powerful starter generator instead of regular units. It switched on for a short time at peak loads and provided an additional 10-20 kW power. Later, technology began to be used to reduce fuel consumption by installing traction batteries and electric motors in the vehicle, capable of operating under load for a long time.


  • Connecting the electric drive through an additional differential to the base drive system

The scheme uses an additional differential to transfer the torque from the electric motor to the standard driving wheels. In cars with a full drive disconnect one of the axles and connect the electric drive to its place.


Whichever scheme is a modified car, it almost in 100% of cases gives way to the original hybrid not only by reliability or technical characteristics, but also by price. The cost of processing, even without the price of the donor, can range from $ 3000-5000 to several tens of thousands of US dollars. It's not a fact that the newly created hybrid will work as it would be desirable to the author or the customer.
