They announce a new generation of Range Extender drives for electric cars

Horse, the company based in Spain that brings together the combustion and hybrid engine business of Renault and Geely (both with 40% shares) has presented a new generation of engines that will function as technology Range Extender for passenger and commercial cars.

Today there are very few models with this type of propulsion system. These are 100% electric vehicles but with a combustion engine that generates electricity that charges the battery. The Nissan Qashqai and Nissan Ford had a similar system in its 2017 Tourneo Custom van and the Chevrolet Volt or the first-generation Opel Ampera also worked this way.

The system presented by Horse has a battery that provides 200 km of 100% electric autonomy and the internal combustion engine adds another 600 km of range (for a total of 800 km of autonomy). In this way it is possible to have a vehicle with the possibility of entering low emission zones and capable of taking on long trips without fear of recharging problems.

The high-voltage battery is about half the size of a car battery.
pure electric, which means savings in costs and weight… and it is necessary to exploit a smaller amount of minerals. This battery can be charged in a similar way to that of a 100% electric vehicle, from a home socket or from a public charger.

The engine serves as an on-board power source for the vehicle's battery, feeding it to
through an electric generator (power of 50 kW in passenger cars and 80 kW in light commercial vehicles). It maintains a constant charge level of the high-voltage battery, which is used to power the electric motor. As this block operates in the most efficient rev range, it minimizes fuel consumption and emissions. When the battery has enough charge, the combustion engine switches off automatically.

Horse CEO Patrice Haettel indicates that there are a variety of power generation solutions and that “we are developing next-generation hybrids, range extenders, and synthetic and hydrogen energy solutions.”

This is an interesting solution since, if that internal combustion engine works with a low-carbon fuel, the carbon footprint of an extended-range electric vehicle is very low. This Range Extender technology could work in any existing vehicle architecture, whether for an electric car or powered by combustion engines. The size of the battery (not excessive) makes it easier to install.

Happy drivers
