MotoCzysz E1pc

[NeilBlanchard]

Wow! (say: MO-toe-sizz)



Lots of info from: Gallery: The 2010 MotoCzysz E1pc | Popular Science

12.5kWh lithium polymer battery pack
10X 1.25kWh hot swappable battery cells
~500V [Edit: this may not be the correct voltage?]
100HP 250ft/lb continuous internal permanent magnet motor
~140mph top speed

~40 mile range in race conditions
~113MPGe in race conditions (at worst?)

So, the battery pack weighs ~180-195 pounds, and I'm guessing the motor and the frame and wheels weigh ~100-125? So, say ~325 pounds total? [Edit: the motor apparently weighs 77 pounds, so that probably means the bike as a whole is ~350 pounds?]

Wow.



I have not heard anything about pricing. Michael Czysz said in an interview video that he is more interested in licensing and further development than in production.

I think they could make a small improvement on the aerodynamics by using the concept that John Britten used for cooling: a small intake right at the nose of the fairing and a high velocity duct to a radiator behind the rider's seat; which forms the tapering shape to help the air close in more cleanly. Czysz is already doing something similar with some of the cooling air (it exhausts under the seat), but the medium sized radiator down low and in front could be much more effective and smaller if it was set up like the Britten, I think.

From the AutoBlog Green thread on the MotoCzysz E1pc:

Motor
The MotoCzysz LQ (liquid cooled) IPM (internal permanent magnet) 75kW/100hp
electric motor is one of the highest torque/density motors in the industry
(250+ft/lbs/340+Nm continuous 77lbs/35kg). The IPM solution generates more
torque while being more efficient than any comparably sized AC induction
motor. The MotoCzysz patent pending cooling system elevates the motor?s
nominal power output closer to the motor?s peak power output. The MotoCzysz
motor can deliver a continuous 75kW (100hp) and is 93% efficient under
continuous heavy load (140C). The motor is available to accommodate either
right or left hand chain drive.

Controller
The MotoCzysz LQ 240V 85kW Controller is specifically optimized for the
motor, in both function and packaging. Accepting 240V and 350+ amps the
sealed Controller contains ALL the high voltage components and plugs
directly into the motor, resulting in a nearly completely wireless (high
voltage) system. The Controller receives battery motor and rider command
data and adjusts current accordingly. The Controller software has multiple
embedded maps for setting or customizing functions like torque contouring
and overall power settings.

Batteries, ESS
MotoCzysz is currently the only EV manufacturer utilizing a functioning 'hot
swap' battery solution and the MotoCzysz eDD system incorporates the latest
generation. The new D1g1tal battery pack utilizes high density, high
discharge LiPo (Lithium Polymer) cells. Each pack is embedded with
monitoring capability that sends vital data wirelessly via IR (infrared) to
a DVMS (d1g1tal Vehicle Management System) and ultimately to the Controller.
Additionally, each battery pack houses an LED display that indicates the
overall pack as well as individual cell group data.

Each MotoCzysz (patent pending) D1g1tal Battery pack weighs less than 18lbs
and effortlessly "snaps" into the "suitcase" chassis.

Oh my goodness. Can you say AKIRA?!?!?!?

Well, kinda' sorta'... I've never heard of Akira.

The technology on the MotoCzysz is deserving of a scifi movie? The battery and the motor are ahead of their time.
