The subsequent electrical drive era for the ID. household is now being launched. With the brand new APP550 rear-wheel drive, Volkswagen’s electrical mannequin household will obtain a very newly developed energy unit.
In future, this can supply increased efficiency mixed with improved effectivity for the ID. fashions. The ID. household will subsequently profit each when it comes to energy and elevated vary. Volkswagen is planning to ship the primary autos with the brand new drive era in a 210 kW (286 PS) model from the top of the yr.
The design foundation for the brand new drive stays the modular electrical drive (MEB) matrix, Volkswagen’s car structure tailor-made particularly for electrical fashions.
Karsten Bennewitz, Head of Powertrain and Vitality Programs in Growth: “As a result of the obtainable area has not modified, we had been compelled to develop a brand new drive that achieves vital enhancements in efficiency and effectivity regardless of being topic to the identical constraints. That was an excellent problem for the staff of Technical Growth and Group Elements. The outcome exhibits that we had been in a position to cut back using uncooked supplies, whereas on the similar time attaining a substantial improve in car effectivity.”
The brand new powertrain has an output of 210 kW (286 PS) with a most torque of round 550 Nm – relying on the car’s gear ratio. The considerably increased torque particularly ensures superior energy improvement – each from standstill and at increased speeds. The brand new APP550 electrical drive achieves its excessive torque because of an enhanced stator with the next efficient variety of windings and a bigger wire cross-section. The rotor as its counterpart is supplied with a extra highly effective everlasting magnet that has the next load capability.
The drive was additionally strengthened to face up to the appreciable torques produced.
The present is a decisive issue for the facility of an electrical drive. As an additional necessary element, the inverter was developed in order that it is ready to provide the excessive section currents wanted for better energy and effectivity. It acts because the controlling “mind” within the powertrain whose useful software program ensures environment friendly system processes. This is applicable to the clock frequencies and the modulation strategies for era of the alternating present for the electrical drive motor, for instance. The drive motor can subsequently function extra effectively, relying on the load section.
As a way to improve the effectivity of the electrical drive, Volkswagen optimised a lot of parts within the powertrain, together with the thermal administration system. The brand new drive subsequently has an energy-saving cooling system that operates with out an electrically pushed oil pump. The system is ready to independently cool itself by way of the gear wheels of the gearbox and specifically fashioned parts for oil provide and distribution. The heated oil is cooled by the car’s coolant circuit, which retains the drive at working temperature. The surface of the stator is supplied with a water warmth sink.
The drive system with gearbox, rotor and stator shall be produced on the Volkswagen Group Elements plant in Kassel.
Alexander Krick, Head of Technical Growth E-Drive, Energy Electronics & Transmission at Group Elements: “Now we have been growing electrical drive motors and their gearboxes for 15 years now, and have additionally been producing them right here at our location for over 10 years.”
Product and course of improvements within the electrical drive motor and gearbox end in a major improve in effectivity and efficiency.
Krick: “Drawing on our a few years of expertise, we optimised the general system by, amongst different issues, using particular electrical sheets and customised machining processes, and had been thus in a position to considerably improve effectivity.”
