It's TT time again with the second running of the Elecric Superbike class. Last years winners Agni Motors have been eclipsed in practice by the MotoCzysz team. Mark Miller did the quickest pace yet for an electric motorcycle during the Isle of Man TT of 94.66 mph around the 37.7-mile course aboard the MotoCzysz E1pc. We thought we'd have a closer look at their machine.
The 2010 E1pc D1g1tal Superbike has a liquid cooled PM (permanent magnet) 75kW (100hp) electric motor with a torque density of 250+ft/lbs/340+Nm continuous 77lbs/35kg.
The PM 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.
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.
MotoCzysz has designed the “suitcase” chassis to optimize the ESS mass location and vehicle’s overall on board energy density. The chassis accommodates virtually any modern double sided swingarm from a 1,000cc motorcycle. The suitcase also ships with a matching top plate for the mounting/fabrication of a new or existing front end.
