During the festival, the batteries of the cars are partially discharged. The power fromthe battery can be used for cooling drinks, lighting, a limited sound system, an air castle, charging electric bicycles, etc. All kinds of things for which a diesel generator is normally used. For all this, AirQon uses smart bi-directional technology. An inverter is used in combination with a buffer battery for discharging. This buffer ensures that power can be supplied constantly, so there is always certainty. The power never fails. This also makes it possible to swap cars with another car or to top up a car if necessary. Thus, the power supply is guaranteed.
