Lotus Elon

1969 Analogue Lotus Elan reborn without noise & smells. Same weight to keep handling balance

I now appreciate the constant wh/mile and range read outs of modern EV's. #netgainmotors hyper⁹ is an unusual motor with peak mid throttle efficiency at quite low rpm.

VERY crude calcs seem to show I'm getting c200 wh/mile @60/70mph but suspect that's not very accurate as having way too much fun to watch the gauges 😉 #electricclassiccar

Wag in carpark "who loves ya, baby" 😆 #austinpowers

Thanks for the Juice @Tesco and @pod_point - 40mph free charge in Blandford #electricclassiccar #LotusElan #simpBMS #netgainmotors #LotusElon #sustainableliving

Tesla Talks to Elon 🙂 6.6kW of Sun pouring in (via PV and PW)

Testing .. Tough Job !
Learning a lot:
Torque from 0 is A-mazing Imagine: pulling out of a T-junction onto a main road, in Top Gear, with a TwinCam ? ..effortless, and in silence with #netgainmotors #hyper9.
But working out Wh/mile and range is a PIA ! (Production #EV's spoil us with this info). Needs more testing 😎. #LotusElan #electricclassiccar #diyev #LotusElon

Charging with Sun.
#LotusElon #solaredge
#Elcon 6.6kW controlled by #simpBMS #Tesla modules along with #netgainmotors ... all playing nice. #LotusElan #electricclassiccar #diyev #postlockdown #appreciation

Guilt-free range testing #netgainmotors software tuning, energy monitoring .. all while trying not to have too much fun. #LotusElan #LotusElon #keeping2m #poweredbythesun #simpBMS

AVC2 and charge contols in (lockable) boot. Sends pilot signal to public charge points, turns on #simpBMS to control 6.6kW onboard charger with 2 charge rate options: full 60A or ~20A (adjustable in simpBMS). Simple and works a treat 👍 #LotusElan #netgainmotors #electricclassiccar #LotusElon

Original #netgainmotors controller was dead, now alive 🤟
Good news: i/o's internally fuse protected. Bad news: all tiny surface mount devices. Good news: micro surgery worked ! Thanks to Hunter for advice and Richard for replacement. #hyper9 #electricclassiccar #LotusElan #LotusElon #LockDownNerd #diyev #SpareFatController 😆

Little hack to adjust suspension. (Can you spot it #Lotus folk ?). Better stance and oh so nerd "horizontal wishbones". #LotusElan #lockdown #LotusElon #electricclassiccar

Front Suspension tweaks today. Lowering a tad, (damn lightweight batteries 😆) . Adding a slightly thicker TTR anti-roll bar. #LotusElan #lockdown #LotusElon #electricclassiccar

And .. back together .. next onto the front. #LotusElan #LotusElon #lockdown

My favourite tool ATM ... Spring compressor 👍 note to Colin: could do better on unsprung weight 😆 #LotusElan #LotusElon

Sitting too high ...... batteries are lighter than tank of fuel, exhaust, spare wheel etc. So springing into more #lockdown action to get same F-R weight distribution and legendary horizontal wishbones #LotusElan #electricclassiccar #LotusElon #diyev

Long Drive ! (About 20 meters) in #LotusElon #netgainmotors #simpBMS #lockdown #LotusElan

Bit of 'netbrain' surgery today 😆 Thanks to @electricclassiccars for posting replacement brain (old one - back to #netgainmotors for therapy 🙂 ) .. Lockdown means only posing, no testing. Still, got plenty more tasks to do.
Notes to avoid expensive 'brainstorm' spikes:
1. DO NOT use master switch except in emergency - it's not an on/off switch .. ( that's the key switch).
2. Do not connect anything ( gauges, switched devices etc. ) across HV + and - that has any chance of shorting or spiking.
Good to be mobile again even if only 20m 😆

Finalising rear loom before wrapping: #charge #handshake #AVC2 #V2G #solderjoints.
Love the colour of the #Tesla cooling fluid.
#LotusElan #lockdown #simpBMS #netgainmotors #electricclassiccar #EV

Well that's blown testing ! #lockdown ...... this little instrument short didn't help either 🤭
Notes to self: only use main HV isolation switch when absolutely necessary ! #spikes did this, which took out low voltage side of #netgain #hyper9 controller.
Good news: @electricclassiccars have replacements, and hopefully @netgain can repair.
Bad news #lockdown
Good news: loads to do: suspension, interior, rack etc etc.

Heating-Cooling system using Bonsai Fan Coil servo controlled valves (from an earlier project https://mas-design.com/bonsai/ )

Data logs: pulling 800 Amps when not fully charged, sure sags Voltage !

People have asked about how the weight and weight distribution, has been done to match the original. This shows the layout (datasheet: https://issuu.com/mark77a/docs/1_page_attachment_incl_basic_murray_on_elan_ ) #LotusElan #electricclassiccar #EV #LotusElon #Tesla

Testing (tough job 😉 ) #torque vs #gearing (torque wins, mostly). Pulls cleanly from zero in top gear for motorways. 3rd is perfect for twisties, 2nd 'quick' 😆.. 1st holy smoke - tyre shredder 👼

Battery cooling and heating system in. MOT'D by Poole Motors, EV and Hybrid specialists (for life: Historic). Happy Days 😃

Insurance - Check ☑️ "Converted to Electric"
Great, comprehensive and affordable #electricclassiccar insurance thanks to @footmanjames #LotusElan #Historic #EV #LotusElon

Fitting heating/cooling pipes to rear 2 #Tesla battery modules. Low pressure, lowish heat so thank goodness for John Guest pipes and fittings. #LotusElan #electricclassiccar #diyev #LotusElon

Got V2G working 👍 (ok V2H .. Vehicle to Home). 2x more battery capacity in #LotusElon than in our PowerWall 2 ... RE-Sult 😃 #poweredbythesun #electricclassiccar #EV #Tesla #v2g

THE most important test ... Does a folding bike still fit into this tiny #EV ?? YES !
#multimodaltransport #Strida for town, #LotusElon for road and track #electricclassiccar

Filling up with sunshine.
#PV #solarpower #FreeEnergy #LotusElan #poweredbythesun #simpBMS feeding #Tesla #batteries nicely.

Testing - Tough Job !
Regen working great.

Normally I prefer the purity of no badges (S4, Championship etc.) But this had to stay 🤭
