I understand they use different drive trains and that the entire system is built differently, but aren’t there still moving parts that should be lubricated and maintained?
Thanks in advance.

Engine oil in a normal car is pumped around the engine to lube all the moving parts.
Electric cars don’t have an engine so they don’t need engine oil.
Transmission fluid in a normal car is used to lubricate the gears and to act as hydraulic fluid to actuate the moving parts in the transmission.
Electric cars are usually a single fixed gear ratio so they don’t have a transmission.
The one oil that electric cars DO have is usually gear oil in the drive unit. The fixed gears still need lubrication and for single-motor axles the differential needs lubrication too. Typically this oil will last the life of the vehicle because it’s not exposed to extreme heat, combustion products or friction material from a transmission, but you could technically change it if you wanted to.
