Video: Hybrid Booster Moves The Car Without Switching On The Combustion Engine
Whether for steering, brakes, drive train or air conditioning - almost all motors and drives of the mechatronics specialist have to work with different operating voltages so that they can also be used in hybrid or electric cars. Brose supports automobile manufacturers with an economical solution: A cross-product motor and electronics kit with standardized components covers voltages up to 810 V. The decades of experience and proven technologies are thus transferred to electrified vehicles. Regardless of the vehicle drive, car manufacturers benefit from short development times, robust products, high flexibility and economies of scale in global production. Brose today supplies around 200 million engines worldwide in various applications for the automotive industry.
New development: 48 V hybrid booster
Brose extends the performance range of its motors to over 15 kilowatts. It includes, for example, auxiliary units such as the electric oil pump or the newly developed 48 V auxiliary drive for mild hybrid vehicles. If necessary, this supports the main motor. With up to 80 Nm of torque, it can move the car in certain situations without switching on the combustion engine, for example in a traffic jam or parking garage. The hybrid booster can be used at different points in the drive train and therefore in different hybrid concepts. It is also characterized by a particularly compact design, low weight and high efficiency of over 92 percent.
Focus on system solutions: electric refrigerant compressors
Brose uses its core competence in the connection of mechanics, electrics and electronics also with electrified ancillaries. One example is the electric refrigerant compressor, in which the engine, compressor unit and power electronics are combined to form an optimally coordinated system. In contrast to the conventionally powered versions of the combustion engine, it only runs when required and is therefore more economical. It can be used in on-board networks from 48 to 810 V and works with both chemical refrigerants and CO2. In addition, it can be used as a heat pump and thus ensures heating and cooling of the interior, if desired, even before getting in. The Brose refrigerant compressor with its high power density is particularly well suited for electric vehicles,because the battery and thus the range are loaded as little as possible. The first orders were placed just two years after the product was first presented. Series production will start in 2020.
Competence expansion for e-mobility
Air conditioning is not the only challenge for cars without an internal combustion engine: due to the space requirements of the batteries, the wheelbase is extended and the familiar driving experience is lost. Brose shows a new drive for the rear axle steering at the IAA, which prevents exactly that. It reduces the turning circle, increases driving dynamics and thus driving comfort, especially when parking or changing lanes at high speeds. Customers can trust the tried-and-tested technology and the in-depth know-how that Brose has already developed for front axle steering. (yup)
