The advent of electrification has led several companies to develop new solutions dedicated to this form of mobility. electric cars are normally characterized by the absence of a real gearbox. Bosch, however, believes that a continuously variable transmission (CVT) can improve performance and efficiency, at least in some contexts. Consider, for example, the long stretches of the motorway driving at high speed, the steep climbs with heavy loads and the towing of trailers.
In all these situations, the battery charge is rapidly reduced. This is why, according to Bosch, in such scenarios a multi & ugrave; speed it could bring a number of benefits. To prove his point, Bosch implemented a specific continuously variable transmission (CVT) inside an electric test vehicle.
BETTER PERFORMANCE AND CONSUMPTION 
renamed CVT4EV , increases performance up to 4% . Depending on the context it can & ograve; offer more torque, better acceleration or speed; maximum pi & ugrave; high.
Since & eacute; the transmission continuously adjusts the ratio without loss of traction, ease & agrave; driving, typical of electric vehicles, is maintained.
Bosch says this transmission offers the “ best possible balance of efficiency and performance ''. At low speeds, a slower gear low allows for improved acceleration and maneuverability uphill. One more gear high, on the other hand, improves both speed; maximum and both efficiency (consumption) at high speeds. Also, this change provides more; torque when towing and off-road driving, while still leading the car to consume less energy. In particular, at speed; constant, the CVT4EV reduces the vehicle's energy demand.
Thanks to the electric motor's reduced torque and speed requirements, a less expensive and more expensive motor. compact can & ograve; provide the same or better performance. Alternatively, the same engine can & ograve; achieve greater autonomy. Electric vehicle manufacturers can therefore find the optimal balance between capacity; and battery life.
Therefore, using the CVT gearbox manufacturers could adopt more engines. small and cheap and smaller capacity batteries; and therefore less expensive, still obtaining interesting performances and autonomies. According to Bosch, his solution is; suitable for a large variety; of vehicles, from mid-size cars to sports cars to light commercial vehicles. The use of CVT4EV also allows different modes; driving for more & ugrave; types of vehicles. In this way, car manufacturers will be able to offer their customers that driving experience typical of all their cars.
