Charge Time Calculator: Configured for Atto 3.

Date Published:

[forminator_form id=”23763″]

Calculator notes and instructions.

The three modes:

  1. Time to charge to %: just fill in the initial charge percentage and the desired charge level.
  2. Time to charge (and charge %) to have a desired range.
  3. Time to charge (and charge %) to add desired additional range.

Time is currently minutes, not minutes and seconds.

I have significant analysis of EVs in general, and some of the Atto 3 in specific, as I feel it represents the start of a 3rd wave of EVs. As I get more data, I will update calculations.

All charge times are best case scenarios, as many things can delay charging, including the charger breaking down as you go to use it, or someone else plugging in to the only available charger just as you arrive.

Apps like a better route planner have built in calculations, but these do not always match people experiences with vehicles, particularly newly released vehicles. This calculator allows modifying the charge curve data to get result consistent with a person’s experience. Plus it is easy to calculate times for alternative plans, and use together with other route planning.

This is a first version, and will adapt to feedback. I suspect it is slightly optimistic, as currently only calculates time under ‘ideal’ circumstances. Plus there is the time for plugging in an getting the charger started to be added.

Atto 3 Charge ‘Curve’.

Charge curve from BYD via EVs & Beyond NZ.

It is not clear if this data is ‘charge added’, or ‘power to the battery’, or even power sent from the charger.
In all cases there will be some losses. The ‘losses’ field can be adjusted to allow for this.

Further, this curve is under ideal conditions. As noted on the Atto 3 page, people have recorded very different charge curves in extreme temperatures, or on chargers with more real world constratiants.

Updates.

  • *2022 September 28: Added charge loss calculations and moved loss setting to 1st page.
  • 2022 September 27: Initial version.

Features to be added:

  • Ability to save charging curves for different vehicles.
  • Currently assumes >= 150kW charger, other charger options to be added.

If people find this useful, please indicate with likes (page top right), and then I will keep updating.

EV Charging Systems: Reference

May 20, 2021 May 10, 2021

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.

EV Range & Economy: Decoding the Numbers.

May 1, 2021 May 24, 2022

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?

Electric Cars: 2021, EVs Just Don’t add up (yet).

April 19, 2021 April 19, 2021

Right now, without subsidies, buying an electric car does not objectively add up. Currently there is a price premium, and as a result EVs only appeal to those happy to pay a premium to indulge a passion.
Some buyers are prepared to pay a premium for the environment, “the future” or the acceleration, but right now, buying is driven by passion and/or subsidies.

Hydrogen facts: No, it’s not abundant on Earth. Nor green nor an energy source, but energy storage.

April 13, 2021 December 1, 2023

There is much talk of a ‘hydrogen economy’. A hydrogen future has long been the dream of the fossil fuel industry, and much of the traditional automotive industry, but what is the nature of the element hydrogen that is behind it all?

There are clear practical uses for hydrogen, but the questionable hype is the use of hydrogen as a fuel or in energy storage.

It turns out much of the attraction around hydrogen fuel is that it can generate a value chain for suppliers as it more expensive than alternatives and could provide a revenue future for the fossil fuel industry, if only a reason to compel its adoption despite the cost barriers. This is a look at hydrogen itself, its abundance, and the blue and green etc sources of hydrogen, as background for pages on hydrogen cars vs EVs, on carbon capture, and for this page highlighting which “hydrogen projects are viable, and which are scams?”

EV, Hybrid or ICE: Pros & Cons of HEV, PHEV, EREV, Gas/Petrol/Diesel (ICEV), BEV (Electric)?

July 10, 2019 March 8, 2023

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).
