MotoCzysz <http://www.motoczysz.com> E1pc raced at the Isle of
Man<http://en.wikipedia.org/wiki/Isle_of_man_tt>TT this week. They won
the class and very nearly took the 10K GBP prize for
first electric 100 mph lap.

The pride of Portland!

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.

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. The "suitcase" holds 8
battery packs for a total ESS (energy storage system) of 10kWh.
