Although uncommon, a vehicle with an internal combustion engine can be converted to an all-electric vehicle by completely removing the engine and adding a battery pack, one or more electric motors, high-voltage cables, and instrumentation. To choose the right EV conversion size, consider your vehicle's size and weight, desired driving range, performance goals, driving conditions, and budget, primarily focusing on selecting a motor and battery combination that provides enough power for your needs while maintaining an appropriate range and fitting within your budget constraints.
