Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The Swiss company Climeworks is building the world’s largest direct air capture (DAC) and storage facility for converting atmospheric CO 2 to rock in Iceland. The particularly high geothermal energy means that the Earth’s heat can be converted to electricity cost-effectively and virtually CO 2 neutrally.

Volkswagen’s ID.3 debuts for the European market

Green Car Congress

The power electronics control the high-voltage energy flow between motor and battery and in this process, the system converts the direct current (DC) stored in the battery to alternating current (AC) for the drive motor. The 12 V DC electrical system is simultaneously supplied with low voltage by a DC/DC converter. Visually, ID.

Volkswagen’s first two production battery-electric vehicles debut at Frankfurt

Green Car Congress

In doing so the power electronics convert the direct current (DC) stored in the battery into alternating current (AC) and use this to drive the motor. Via a DC/DC converter it also supplies the vehicle’s circuitry with voltage of 12 V. In generator mode, meanwhile, the alternating current is rectified for charging the battery.
