    Imagine an EV world, where there are hundreds of EV options on the market and auto magazines have developed a rich suite of things to use in their comparisons and shootouts and recommendation articles.
    Here are some of the things I imagine would be in the checklists/comparisons instead of stuff like: DOHC,VTEC,cylinder count, engine displacement,transmission details,gear ratios, fuel tank size. pushrod vs overhead cam, valves per cylinder, sparkplug type, horsepower/torque curves...
    Along with some possible example numbers or options - most based on todays technology, but some are my pipe dreams.


    Definitions:
    sim = standard ideal miles ( miles at constant 55mph )
    simph = standard ideal miles gained over time charging


    Drivetrain:
    max regen power: 20kW/40kW/50kW
    regen on: brake pedal/throttle pedal/blended
    regen selections: not selectable/dashboard adjustable on/off/mode
    regen efficiency ( energy recovered ): 68%/70%/72%

    Charging:
    max onboard charging power: 3.3kW/10kW/20kW
    ( in imph for your car: 10mph/35mph/70mph )
    charging connectors supported: J1772,Mennekes,Tesla,Brobdignagian
    charging connectors included: J1772,Mennekes,Tesla,Brobdignagian
    3-phase charging: yes/no
    charging efficiency: 90%/92%/95%

    fast charging standards supported: CHAdeMO 50kW , SAE 50kW, Tesla 90kW,EMega 200kW
    fast charging connectors included: CHAdeMO 50kW, SAE 50kW, Tesla 90kW,EMega 200kW
    ( in mph for your car: 100mph/100mph/200mph,400mph )
    fast charging max charge: 80%/85%/90%
    charging efficiency: 90%/92%/95%

    wireless charging standards supported: ViFi,HighDrive TollPay ( highway embedded charging )
    wireless charging max power 5kW/10kW/20kW
    wireless charging efficiency: 70%/80%/90%

    V2G support:
    yes/no

    Backup power option:
    1kW/2kW/5kW/10kW/none

    Battery:
    battery capacity: 24kWh/40kWh/60kWhr/85kWhr
    battery chemistry: LiFePo4,LiCo,LiMnPoFo
    link to battery capacity lifetime curves over time as calculated by: manufacturer [link] / consumer reports: [link] / BatLab Ltd. [link]
    link to used battery value charts in the secondary market [link]
    3rd party non-OEM battery suppliers supported: Panasonyo/LGWooo/B456
    user replaceable module size: 3kW/6kW/entire battery/ not available
    battery swap standards supported: none

    Range:
    ( section with standard features & section with loaded max efficiency features )
    standard ideal miles: 100/160/300
    wh/mile at constant speeds: 35mph,45mph,55mph,65mph,75mph:
    range at constant speeds: 35mph,45mph,55mph,65mph,75mph:
    USLA4 city cycle: 100 miles/160 miles/300 miles
    70mph real world highway cycle: 73 miles/130 miles/260 miles
    low battery warning level: 2%,3%,5%

    Efficiency options:
    - aerodynamic wheels [link to calculation of improvement over standard]
    - rear wheel skirts [link to calculation of improvement over standard]
    - extending tail wing ( opposite of spoiler - reduces drag ) [link to calculation of improvement over standard]
    - side view cameras instead of mirrors [link to calculation of improvement over standard]

    Dimensions:
    Center of mass: height from ground in inches

    Let's go to the BatLab, Robin!
    {nananana nananana}

    Sorry, couldn't hep myself. V2G support will be more than yes/no; we'll see full/charging/none

    Where
    full=regulation up, regulation down, spinning reserves, energy, dispatchable charging
    charging=regulation down, dispatchable charging

    I also always want added:

    Cabin sound level: DB at 60mph
