#PROTOTYPE 1 HYBRID GENERATOR#
In the prototype, the more powerful motor generator is integrated into the transmission and connected directly to the powertrain rather than to the combustion engine.īoth the electric motor and the internal-combustion engine are separable via a coupler, which means that they can provide power to the wheels independently. At the IAA 2015, Bosch will also be presenting a new second-generation of the entry-level hybrid that is currently still in development. This enables parking in full-electric mode. The electric motor and the internal-combustion engine are separable via a coupler, which means that they can provide power to the wheels independently. In this second generation, the electric motor is integrated into the transmission. The newly developed lithium-ion battery is also significantly smaller.īosch expects some 4 million new vehicles worldwide to be equipped with this type of hybrid powertrain in 2020. A DC/DC converter supplies the car’s 12-volt on-board network from the 48-volt vehicle electrical system. The power electronics form the link between the additional low-voltage battery and the motor generator. The motor generator uses a belt to support the combustion engine with up to 10 kW. Instead of using a large electric traction motor, Bosch enhanced the generator to output four times as much power. Unlike conventional ~400-volt full hybrids, the 48V system can utilize less expensive components.
