Bosch has unveiled electric semitrailers featuring regenerative braking, which the company estimates could save up to $10,000 per year. The system will “integrate an electrical machine into the semitrailer’s axles, instead of simply allowing them to roll freely”, the German auto-parts manufacturer said. This is a similar function to that used in most electric vehicles. In addition to saving money, it also reduces emissions and improves fuel economy. This electricity can be used to cool the truck's refrigeration unit or to boost acceleration during hill starts. The company explains the idea behind the concept: “The idea behind it is to integrate an electrical machine into the semitrailer’s axles, instead of simply allowing them to roll freely, as has been the case up to now. The system is available for new and existing trailers.
