Integrated system for light electric vehicles

In-hub drive unit for easy installation in combination with conventional wheel mounting and suspension systems for power outputs of 0.35 to 3 kW. The strong torque provides dynamic acceleration and ensures plenty of fun while riding.

The compact, fully sealed three-phase permanent magnet motor has a power output of up to 4 kW, is especially quiet, and features impressive torque and powerful acceleration. The central drive unit allows flexible positioning in the vehicle, thus enabling easy integration in different vehicle concepts and designs.

The powerful five-phase central motor converts electrical energy into maximum traction and enables impressive acceleration right from a standing start. The air-cooled motor – which has its origins in automotive production – is highly versatile and can be scaled as needed, thus enabling its use in a wide variety of vehicle types and for different performance classes.

The drive control unit not only ensures optimal motor response and power delivery, it also features smart energy recuperation, enhanced heat protection, and quiet, dynamic acceleration.

The vehicle control unit manages how the components interact with one another. It is the brains behind the powertrain system and, thanks to the smart connections between the individual components, ensures the entire system runs optimally to provide well-balanced vehicle performance.

The connectivity control unit for light electric vehicles acts as the interface between the vehicle, cloud, and smartphone and offers the rider a whole range of additional functions. The control unit can also be used for vehicle control functions, which opens up new possibilities for vehicle manufacturers to implement their special requirements.

The 48 V lithium-ion batteries not only offer an impressive energy density but also satisfy all relevant safety standards. The integrated batteries are built into the vehicle and are equipped with a smart charging algorithm. This algorithm is constantly monitoring the charging current and the battery temperature to avoid overheating and consequential charging interruptions. Thereby, an optimized charging process and an enhanced battery life time can be enabled.

The portable 48 V lithium-ion battery not only offers an impressive energy density but also satisfies high safety standards. Just like the integrated variant, this portable battery can also be used on its own or operated in parallel together with other batteries so that vehicle manufacturers have the flexibility needed to implement their various requirements.

The connectivity cluster for light electric vehicles is the interface between the rider and vehicle. During the journey, it reliably supplies all the relevant vehicle information, such as the speed, battery charge level, and remaining range. The Bosch cluster for light electric vehicles is available in various variants and can be integrated quickly and easily in any vehicle.

Bosch provides smartphone apps specially designed for users of light electric vehicles that enhance the convenience of riding, particularly in urban environments. Riders can, for instance, unlock and lock their e-scooter via an app and view real-time information about the traffic situation; and vehicle data, like the battery charge level, can of course also be transmitted from the e-scooter to the smartphone and displayed in an app.
