Lotus Elon

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

#ORAC Front and rear #Tesla battery modules, plumbed in with high temp clear, PU tube - CU bubbles :-) #electricclassiccar #diyelectriccar #diyev #LotusElan #LotusElon #simpBMS next install into 'The Liberator' #blakes7
Temporary 'rats nest' hooked up with #simpBMS and charger all working 👍 thanks to @tom_evnut for support 🙏. A few v minor tweaks to get current sensing and 'fuel' % accurate (mostly down to my learning 🤭)
Why a #LotusElan, to show the potential of electric vehicles ? : "What’s the best car you've ever driven"? Without hesitation: “Lotus Elan. I’ve never driven anything better. Including the F1.” Gordon Murray CBE. (Evo Magazine, Jul 2018). #Lotus #tesla #diyelectriccar #electricclassiccar #diyev
50 year old #elan Analogue Fuel Gauge now a Battery 'Fuel’ Gauge. Fully controlled by #smpBMS instead of rheostat in tank - using pulse width modulation from @tom_evnut #SOcool #oldskool #LotusElan #diyelectriccar #electricclassiccar #diyev #diyelectriccar #LotusElon #calibrated
911 crashed my BMS 😆 Actually A-mazing #smpBMS firmware upgrade - and charger is not dead 👍 HUGE thanks @tom_evnut #ElonsBrain #LotusElon #diyelectriccar #diyev #LotusElan
The authenticity of analogue is hard to resist. Now 'just' to convert battery's 0 to 100% State of Charge into 5 to 10volt signal. Any suggestions ? #LotusElan #diyelectriccar #diyev #electricclassiccar #electronics #smpBMS #LotusElon
Replacement #LotusElan 'Fuel Gauge' (to fit in dash in 50mm chrome bezel). Thanks @tom_evnut #simpBMS 👍 #electricclassiccar #diyev #LotusElon #poweredbythesun
Ahhh the 'joy' of #diyev 😏... Spent several days messing with cables and canBUS, but I think I've got a duff TC HK-J 6.6Kw charger 😟 "wrong communication" on startup (before it's even initialised). #diyelectriccar #electricclassiccar #LotusElan #atleastindoors
On Board Charger getting wired up .. will hide under the #LotusElan hood tray. #electricclassiccar #diyelectriccar #diyev #LotusElon
Waking up #tesla battery modules up from accident induced coma, 1yr ago, with #simpBMS. Still balanced with 40% SOC. Kudos to Tom de Bree #LotusElon #electricclassiccar #diyelectriccar #diyev #LotusElan
Front battery pack almost complete. I'm calling it "ORAC" (Ai in 80's, BBC Blake's 7) 😆 #LotusElan #diyelectriccar #electricclassiccar #diyev #LotusElon ##tesla #simpBMS
No more putting it off. Additional wiring checked and double checked. Now to start 'weaving'. 😋 #LotusElan #diyev #electricclassiccar #diyelectriccar #LotusElon #lotus #tesla #simpBMS
Power Cables in - 70mm2: enough for 800+ amps (need that to get the full 100Kw from the Tesla Battery Modules #Energy #tesla #diyev #diyelectriccar #electricclassiccar #LotusElan #LotusElon Next: more smaller diameter wiring - rats nests !
Power Cable pre crimping. (Stretching caps over 70mm cable hard part - 1st one took 15mins last: 1minute) #technique #diyelectriccar #diyev #electricclassiccar #LotusElan
Very Cool Controller plate in situ 😆 #diyev #electricclassiccar #LotusElan #lotus #lotuselon
Front battery bay testing 😆 concentrated load - 20kg over ... Elon's on a diet, not me 🤭 #diyev #LotusElan #electricclassiccar #electricvehicle #Lotus #lotuselon
Motor in, with some help of @markbickerstaff (Legend) #diyev #diyelectriccar #LotusElan #electricclassiccar #netgainmotors #lotuselon #lotus #tesla
Rigid conduits in 'exhaust' channel prior to glassing: battery + & -, comms, battery cooling flow & return.. AKA 'worm holes' to the front. #diyelectriccar #electricclassiccar #LotusElan #lotuselon
Access - Starting at the bottom - for main cable, comm's and cooling pipes to rear battery modules. #LotusElan #electricclassiccar #tesla #electricvehicle #lotuselon
Still trying to fool this little 'rvi' fella that it's still connected to a coil and points. Taking longer than many other #electricclassiccar conversion bits #itworkedbefore #LotusElan #joy #lotuselon #analog #electronics
Spot the Difference - EV's don't need 3 pedals. I know sacrilege to some 😃. #LotusElan #electricvehicle #electricclassiccars
Marriage of new and old and an 85kg weight saving 👍 (10kg under original, including batteries l) #electricclassiccars #LotusElan #Tesla #batteriesincluded #addedlightness #Lotus
Always frustrated with Meccano ... Not enough flexibility. #CapHeads #cnc #sorted 😆 #LotusElan #electricclassiccars #LotusElon @mitchellmachining
Coupling ...... Check #electricclassiccars #LotusElan
Eye can see you 😎 #LotusElan #electricclassiccars #Tesla #lowenergy #ledlights
Checking alignment of gearbox mounting, coupling, magnets and spare tacho hall sensor. #phew 🤞 #electricclassiccars #LotusElan #LotusElon #cnc
CNC'd Parts (thank you Greg @mitchellmachining ). Add hall sensor for analogue tacho conversion and almost ready for putting the motor in 👌 #electricclassiccar #LotusElon #LotusElan #ev #upcycle
Load Path Criticality: Electric Power connection to existing #Elan chassis mounting (reversible and strong). #LotusElan #electricclassiccar #cad #fea
FEA of motor mounting under full Torque. #Lotus_Elon #Lotus_Elon #electricclassiccar
Light pod lifter 'joint' reinforced - the original was just a hole in the Fibreglass - I learnt a lot about value engineering design from Lotus designer, Ron Hickman eg brilliant concept of using threads as axles, but this hole was pushing it (literally 😆) #LotusElan #Lotus #RonHickman #hero #inventor
