High-end battery and 900-volt technology. Based on the 800-volt technology of the three-time Le Mans winner, the 919 Hybrid, the Porsche Taycan was the first car to enter production using this system voltage instead of the 400 volts normally used in electric cars. Their shape is reminiscent of hairpins, hence the name.

The electrical system in the e-tron GT concept car runs at 800 volts, whereas most modern EVs currently operate at a capacity of 400 volts or less. Because of this, the e-tron GT is able to charge the battery to 80% in about 20 minutes at a Level 3 DC fast charger with a maximum output of 350 kW.

The power electronics, which convert the direct current (DC) into three-phase alternating current (AC) which is used to drive the motor, are located in the center tunnel. The power electronics also integrate a DC/DC converter, which converts energy from the high-voltage battery to 12 volts to supply the 12-volt electrical system.

The entire fuel cell operates in the voltage range of 230 to 360 volts. The battery operates at a different voltage level than the fuel cell; hence, there is a DC converter (DC/AC) between the two components—this tri-port converter is located behind the stack. The 12-volt battery is also mounted at the rear.

The XL1 is aggressively optimized for efficiency in all areas of its design and technology—from materials (carbon fiber reinforced polymer monocoque); to powertrain (0.8L kWh lithium-ion battery—integrated in the front section of the XL1—supplies the electric motor with 220 volts of electrical energy.

Depending on the load point, the stack operates in the range of 220 to 280 volts. The storage battery operates over the range of 220 to 460 volts—a 3-way DC/DC converter in the engine compartment equalizes the difference compared with the fuel cell’s voltage level. 3-way power DC/DC converter.
