Canadian firm Inmotive has announced the development of a two-speed transmission for electric vehicles. It was named Ingear and promised suitability for vehicles of any class, increased range, improved dynamics with very little increase in the cost of the car.
- The vast majority of electric cars now do not have a gearbox in the usual sense – with several steps. However, Canadian inventors are confident that this does not mean that they should only work according to this scheme. Moreover, there are exceptions to the rules. Two-speed transmissions are found on the production Porsche Taycan and Audi e-tron GT.
- Typically, electric vehicles have two gearboxes between the engine and the wheels. Ingear replaces the second gearbox. In the box, the chain continuously transmits the moment, but depending on the load, it works with a sprocket of large or small diameter. On its YouTube channel, the developer company clearly showed the principle of operation of its brainchild.
- The authors of the project are confident that the autonomy per charge will increase by 7-15%, the acceleration dynamics will improve by at least 15%, and the increase in cost compared to the usual design for an average car will be less than $ 150. In addition, the Ingear box is suitable for all vehicle classes.
- The Inmotive website has published reviews of “experienced electric car drivers” on the operation of the two-stage transmission. Apparently, with a minimum of alterations, it can be introduced into a car, which initially has a single-stage transmission. Because the video shows a Kia Soul EV that doesn’t have an Ingear box from the factory.
Tesla previously filed a patent to develop a structured battery pack that would improve vehicle safety. The idea behind the development is that the battery acts as a part of the car’s frame. Such batteries are planned to be installed on the Cybertruck super pickup truck and the next generation Model Y crossover. They will help electric cars lose up to 10% of the mass, as well as increase mileage by 12%.
