Electric cars were a "mature technology" in 1915
My electric ran on lead-acid batteries and a DC motor, just like an old Baker. The cost for equivalent range on LiOn batteries would be over 5o times as high, and they were not available when I had mine. The chager would be more expensive too.
For the same weight, the range would have been WAY more, along with the price.
Newer motor control systems are a lot more efficient too - and a top line PWM FET controller today is about half the price an old GE SCR or ALLIS Transistorized controller was in the '80s. (and a lot smaller, lighter, and more efficient - with more features)
