Rheinmetall is a Tier 1 automotive supplier and is part of the TÜV Rheinland Automotive Division and is currently expanding its product line in the electric vehicle sector. At the Frankfurt International Auto Show (IAA) in September this year, the company will showcase a newly developed 90 kW electric drive module and a new modular battery pack. These systems are installed in a compact model as a demonstration vehicle.

Rheinmetall's 90 kW high-voltage motors are suitable for a wide range of applications depending on the output and torque characteristics. The current design is suitable for small models. However, the scalability of the system can also be applied to large models. Rheinmetall chose a synchronous permanent magnet motor. And use concentrated coils to meet limited installation space.

The motor is housed in a compact demonstration vehicle with a battery pack rated at 29 kWh. Thanks to the newly-added electric drive, the vehicle has a top speed of 135 km/h and a mileage of 275 km. At the same time, the trunk space and passenger compartment of the model are not reduced.

In the design of the new battery pack, Rheinmetall's premise is that the future electric and hybrid cars will use a large number of floor batteries, which will not reduce the load carrying capacity of the vehicle to any significant extent, and has advantages in weight distribution and integration. The structure of the vehicle.

The basic structure of the modular battery pack is made of aluminum and can be integrated with customer-specific battery modules. This structural layout is remarkable in terms of its high-density energy and weight, and can be widely and flexibly applied to electric vehicles due to its compact size.

The battery pack has its own cooling system, which is a composite fiber structure developed by the business department of the Rheinmetall Group's military division specializing in system protection to prevent intrusion.

The company sees this configuration as an optional production option for future electric vehicles, allowing other assemblies to meet customer needs.

Rheinmetall has decades of engineering expertise in the electrical drive systems for auxiliary components. As early as 2004, through its subsidiary Pilberg, the first all-electric coolant pump for the main cooling system was developed and successfully used in the six-cylinder BMW engine.
