ICE vs. EV
The transition from internal combustion engine vehicles to electric vehicles is creating a list of winners and losers among auto components.
Here’s a gallery of some of the parts that will be lost and some that will be gained.

LOST
The transition
Nearly 100 traditional ICE components will be eliminated in the shift to EVs, and only a handful will survive the transition unaltered.
No ICE fuel system or exhaust system components are needed in EVs.
gained
EVs will require 41 new components. Most will be electrical or electronic with no moving parts.
Most parts for vehicle suspension and steering systems will transition to EVs with no changes required.

BATTERY PACK
Battery module
Consists of a cluster of interconnected battery cells within a metallic frame to protect the cells from external shock
Battery management system
Electronically manages the power delivery in the battery pack. It monitors the state of the battery and controls the environment.
The inverter converts DC (direct current) power to AC (alternating current) power that is delivered to the e-motor. The unit also regulates and controls the speed of the motor by changing the frequency of the AC.
DC to DC converter
Changes DC power from the onboard high-voltage battery to lower voltages to run in-vehicle systems. The converter also charges the auxiliary battery.
