This is what the front hood looks like with almost everything in place (well almost). At a glance you can see the controller (alltrax axe 7245) , maxwell ultracapacitor module (165F,48V) , 12V auxilliary battery for the headlights.. etc and also most importantly to enable the contactors. I am particularly happy with being able to install the vacuum pump and the vacuum tank for the brake system. the vibrations due to poor mounting of the pump is still a problem though.
The rear compartment is completely taken over by HEAVY trojan 220ah batteries ; 8 of them, totaling almost 240Kg!!! these are cheaper of course and we decided to experiment with these first before getting some lithium ( any sponsors?)
the car look really nice :)
ReplyDeleteNice conversion you got there. Just wondering, are the capacitors installed for better throttle response? if so, are there any significant improvements? Thanks
ReplyDeletethanks ahmida,
ReplyDeletetzy wen, the capacitors (supercapacitors) are installed for a better uphill acceleration as well as to improve range... we got some good results... we are working on improvements .... are u involved in similar work?
manoj: I'm doing some research on electric vehicles. I plan to do an electric conversion on a small car too but haven't gotten around doing so. Very interesting use of capacitors here. I would have thought that the batteries are capable of providing enough surge current during acceleration. Is this car based in Semenyih?
ReplyDeleteTzy: yes the car is based in Semenyih at the university of Nottingham's malaysia campus. If ur in the area just let me know.. i can give u a tour.. Are u attached to any research organisation or a hobbyist? some interesting stuff in your blog.. I dont mind helping you out with ur conversion whenever you get around to starting...
ReplyDeleteAs for the batteries, well yes they can provide enough current , but my research is about downsizing the batteries so we can use lighter supercapacitors.
pretty good work dude...
ReplyDeletei'm impressed...
how much does this total conversion costs?
Sure I'll love to come see it one day. I'm just a hobbyist.
ReplyDeleteWhat sort of supercapacitors are you looking at? They won't completely replace the batteries as storage right?
Do you have msn? easier to keep in touch there.

ReplyDeletehello manoj...would you mind telling me where you bought the dc motor? did you get from Pasar Karat, KL?
ReplyDelete@ haniff where is pasar karat??? i bought the motor from US.
ReplyDeleteIf I convert my car to EV do JPJ recognise it?
ReplyDeleteCan it be use on road?
