I don't know much about the Cybertruck, but in general all modern cars, electrically propulsed or not, have a 12 V system which includes a battery for running electronics and some accessories. Very old cars had a 6 V system. There is a push to move to higher voltages, the battery would also be 48 V to match. https://my.avnet.com/abacus/resources/article/the-shift-to-48v-in-automotive-systems/ https://my.avnet.com/abacus/resources/article/the-shift-to-4...
