Nokia, Palm, Blackberry, and Microsoft had years of experience making smartphones…
In hybrids the electric motor doesn’t have to be maximally efficient, because the electric range is only a nice to have, not the key selling point.
Hybrid battery density doesn’t matter much, because it’s 1/10th of BEV's size anyway.
In hybrids the charging speed can be an abysmal trickle, and still suffice to charge the tiny battery. In BEV you need to work with 4x higher voltages, 10x higher wattage, and push thermal management to the limits.
That’s why bz4x sucks. Its efficiency is meh. It charges at below average speeds, and still overheats.
In hybrids the battery is used primarily to lower average fuel consumption and lower (a lot) noise and fuel consumption in cities (where hybrids run generally a large amount of time on electric).
Maybe for modern hybrids. For my 2005 Hybrid, the engine is an Atkinson cycle engine and that is where most of the efficiency gains come from https://en.m.wikipedia.org/wiki/Toyota_AZ_engine#2AZ-FXE “The large valve overlap leads to a reduction in cylinder charge and reduced torque and power output, but efficiency is increased. This combination makes the 2AZ-FXE suitable for use only in hybrid vehicles, where peak torque and power demands can be met by the electric motor and battery.”
So the hybrid battery is used for acceleration. Note that my Hybrid battery is a 200V 50Wh Nickel metal hydride battery - Note I think Toyota Hybrids didn’t start using Lithium batteries until late 2010’s).
When town driving it doesn’t seem to me that the regenerative braking makes much difference: It is very noticeable that the engine is in use during acceleration from a dead-stop. Certainly regeneration is insignificant on hills because the
