EV Reference Information

To make sense of all the often seemingly conflicting information on "regen", one-pedal-driving, and how to best drive an EV, it really helps to know there are two different systems for how the "STOP pedal", aka the "brake pedal", to works in an EV: 1. Like an ICE vehicle, as with Tesla and perhaps some other EVs. 2. Using brake-by-wire as with most EVs. Confusion over the two systems is part of it, but there are so many myths and so much misinformation about regen-braking and one-pedal-driving "regen braking", and is why a low regen setting can be less efficient in a Tesla, but won't matter and can help in practically all other EVs, and why "one-pedal-driving" is not necessarily the most efficient way of driving. Despite the fact there is so many myths leading to so much misinformation making it sound complex, driving an EV for optimum efficiency is usually extremely simple.

Batteries for EVs have progressed: From: very expensive even while delivering an impractical range.To: Less expensive with an acceptable range. Only now in 2022, are batteries showing signs they can soon enable EVs price competitive and range competitive. With the new world of EVs, comes a whole new world of understanding cars, with batteries at the centre. This page provides background, the rethink batteries bring, the different battery technologies, though to how to car for batteries, and who makes what.

Eventually, EVs will take over, but for most people even price parity EVs are still not 'there yet', and that take over could take 30 years. This webpaper compares vehicle types from "standard" gasoline/petrol and diesel vehicles, with hybrids, plug in hybrids and battery electric vehicles (EVs). There is a separate exploration of hydrogen vs battery electric cars, so this page is pros and cons of hybrids vs "standard" vehicles, or pure battery electric vehicles (EVs).

This page covers a lot. Charging equipment and what to install and how to charge at home, and charging on road trips, through to the technical side, and a look at wireless and the future of charging. Plus, how recharging requires a complete rethink from refuelling, and how charging can be more convenient and match the speed of refueling. Public recharging infrastructure for EVs is growing but recharging at home will be most important for most people. Fully benefiting from having an EV, requires understanding, being prepared for recharging.

For almost 100 years, people have grown up in an age of the internal combustion engine. For many people, this has meant an understanding of engine capacity, cylinders, spark plugs, engine compression, crankshafts, valves, turbochargers, exhausts etc. The bad news is that EVs mean so much that previous literacy is about to be consigned to history and replaced by permanent magnet and induction motors, regen braking, and other new terms. The good news is, it is easy to build and EV literacy on the those ICEV foundations, so there is no need to feel illiterate in this new EV world.

There is a full exploration of recharging electric vehicles on another page, but there is an a "refuelling" alternative to recharging: battery swapping. With electrical appliances in the past, when the batteries went flat, we swapped them. Then rechargeable batteries became popular so we could avoid throwing out the old batteries, but I swap first and then recharge. It turns out, we can also do that with cars, and it is happening already. Battery swapping, take only around 5 minutes, but so does recharging the latest batteries. Battery swapping will likely play a key role in the future, but not necessarily the role many expect.

This is a look at range, covering from how range specs don't mean what you would expect, through why range is so unlike that of fossil fuelled vehicles and optimising range is all about efficiency, through to what range is required around the town or on the highway. Range with EVs is such a different experience that novices can feel anxiety, despite that in practice running out of charge in EVs happens no more than ICE vehicles run out of gas. While EV range is getting closer to ICEV range, most EVs, unlike the Lightyear One pictured here, aren't solar and still don't match the range of internal combustion engine cars, but the convenience of background charging means range with EVs is usually only a limitation on relatively rare road trips.

The key specification for EVs so far has been 'range'. But how are the numbers measured, will range specific match reality, and can the number even be compared? It turns out there are even 3 different standards for measuring range, and they give very different answers! Further, why have we moved from 'economy' to 'range'? Is there still even economy with EVs?

I have been exploring electric vehicles. What is needed to make them affordable, and what it is like to live with them. When exploring charging, the charging systems became so complex that I have extracted what I found as its own exploration, which I plan to keep updated as a reference. It currently does need an update for wireless charging, but some information can be found on my exploration of the logistics of charging.
