The differential on an EV is the same as on an ICE car. It does the same job either way, it doesn't care whether the power source is gas or electricity.
But on an EV, that's basically the only thing that needs somewhat regular "oil changes". Whereas ICE motors & transmissions also need fluid changes regularly.
