Hello Endless Sphere
I basicly been lurking around on this forum for a couple of years, but now it is soon time to take the step.
A step i plan to take with my KMX typhoon, a bike i have been riding sence the beginniing of the summer, 1500km on it so far.
Basicly completly stock exept a bicykle rack, big pannier bags and clipless pedals (a must have for safety on this kinds of tadpoles.)
This bicykle is my only mode of transportation exept public transport.
What i want to achive with this conversion.
Range: 60km (i live in hilly area)
Reability: As stated this is my only mode of transportation exept public transport. It is not used daily but a couple of times every week, Also i plan and will use it around the year.
Velocity: Betwene 50 and 60 km/h, a speed i can comfortably ride it, much over that is probebly asking to much with a stock frame with etro 305 wheels (16'' for those who dont speek SI)
HMI (Human Machine interface): This is a bike. I will pedal it. I am not saying i dont want plenty of power, i am saying i want to contribute to the total power output for three reasons. To keep warm (the westcost of sweden is not exactly sunshine and warm breezes during the winter), keep the aperence more leagal (i will exeed the 250w 25km/h eu regulation. (Of course only in an enclosed area
)), and to lower energy (electrical) consumption.
The Plan so far.
System voltage, planned 88.8V (24s lipo). Motivation that system voltage brings me to the desiered speed with the motors (see below.) Alows the use of switched powersuplies for and auxiliry 12v system. Maximises the potential output of controlers using the IR4110. Also alows the use of 4x 6s 5h turnigy in series (already have a couple of those bricks). more info see below.
Motor. Planing on using either a ht3525 or a MagicPie. Thise motors with the voltaged planed should give me into the target speed.
The two questions are, can i use a 8 speed sprocket? or do i have to go down to 7 or 6? And what rim is the most reliabl? The spoked one of the crystalyte or cast of the MP. The pricedifferens is around 40 euro in favor to the MP. The plan also includes venting the motor (to let mousture out) and rustproofing the stator. A temperature probe inside it coupeld to a CA seems like must have. A set of good tourquearms is also on the "stuff to get" list.
Controler Vbat max 100v, with a low inductance morot as the ht3525 and MP, so te question is: is it ok to use 100V max controler or not. Sence i plan to run a separe shunt derfore a cycle analyst conector is not of the essence. Anyone have any recomendations exept lyen?
Planned current is abow 50A, with wild visions of 100A+.
Battery: Sence i have a couple of the turnigy 6s 5AH bricks laying around i plan to use them (along with a few new) in to a 88.8V 15Ah pack 1.3KWh. This should get me into and abow the range i need, also with not strain the cells to much either. I plan to devide the battery in two banks, 12s3p each. In this way i increase safety, by only conect them in series while riding, the conection betwene them will also serve as a system main shutdown, using an kilovac EV200 relay, this will also serve as an emergency switch.
Where to locate the battery is another question, underneath the seat seem like the best place packingwise, wonder if it will uppset the weightdistrubution to much.
Charging. Starting with how i think to use them. Planed max cell voltage 4.15V. After a ride charge them to storage voltage (around 60% capacity), Before a ride charge up the rest of the capacity in about 30min. For this i need around 1KW of charing.
Using this method i can always in the same room while charging.
Either using a bulk charger (BMSBattery?) together with Methods lipo protection kit. OR, using 2x Hyperion 1420.
Brakes: Planing on uppgrading the stock front brakes to Hygia Multi http://www.hygia.com.tw/liveshop/index.php?route=product/product&path=49_64&product_id=82. I probebly uppgrade to 203mm rotors aswell.
The question is, am i on the right way? or have i messed up somwhere in the planning?
