Details on the Mercedes-Benz EQ Boost technology
May 13 2020,
The letters EQ are increasingly present in the Mercedes-Benz vocabulary. Of course, they will be used to designate all the electrical products that the brand will be launching, but in the meantime, they are also used to designate electrification technology that serves models equipped with combustion engines.
Let us look at what that technology is
EQ Boost technology is a mild hybrid system built around a 48-volt electrical architecture. The centerpiece is an Integrated Starter Generator. This compact-sized unit, which combines a starter, alternator and electric motor, is positioned between the engine and transmission and acts as both a starter and a hybrid assist motor, while allowing the regeneration of kinetic energy.
Its advantages are multiple
For example, the EQ Boost system increases the power of the Mercedes-Benz 6-cylinder engine by 21 horsepower and 184 pound-feet of torque in the case of the 53 AMG versions. It also allows the powertrain to "take a break" under certain driving conditions (Eco mode) to help improve fuel economy. It also powers the 48-volt electrical system that supports the standard 12-volt electrical system.
The recovery of kinetic energy, as mentioned above, increases the car's efficiency. The 48-volt system can also power the water pump and air conditioning compressor, eliminating the need for belt-driven accessories, reducing parasitic power loss and freeing up space. Finally, 48-volt power is less expensive than plug-in hybrid technology.
Beyond all these technical details, there's one thing to remember. The system's primary objective is to improve power delivery while promoting better fuel economy. In these respects, it accomplishes its mission.
