The ECTA is excited to announce the addition of a new motorcycle class premiering in  2012.    ECTA's Board has been working closely with Dr. Robert Prins from James Madison University, to develop the new Electric Motorcycle class.  We are also pleased to announce that Rob has graciously agreed to chair as Chief Technical Advisor for this new world of electric motorcycles.  Below please find a few of the highlights of this class.  A complete list of the safety and technical requirements will be included in the 2012 ECTA Rulebook.

ECTA Electric Motorcycle Voltage Divisions

Division

Measured Voltage

A3

382.9 and above

A2

330.1 – 382.2

A

264.1 – 330.0

B

211.3 – 264.0

C

184.9 – 211.2

D

158.5 – 184.8

E

132.1 – 158.4

F

105.7 – 132.0

G

79.3 – 105.6

H

0 – 79.2

Maximum voltage cap is 500 Volts.

Required additional logbook data for electrics for each event including:

  1.  number of cells
  2. nominal voltage of cells
  3. nominal voltage of pack
  4. fully charged voltage of pack 

In the event of parallel cells, cell combinations must be “hard wired”, series/parallel switches are not allowed

Voltage verification points must be demonstrated and accessible for inspection.  Controller input lugs or battery charging connections are some examples of acceptable locations.

Traction Battery Pack

Traction battery pack must be rechargeable

 

Driver must be shielded from traction battery by a barrier, holes in the barrier to accommodate cables and other wiring are acceptable so long as they are reasonably identifiable as such and not just large voids that cables happen to run through if batteries are placed in a box the box is considered a barrier, boxes must be vented

 

Batteries must be installed using appropriately sized metal hold downs, framework, and fasteners; battery installation should be such that batteries will withstand rollover without flying loose batteries with free liquid (such as flooded lead-acid batteries) are not allowed

Over Current Protection

All battery packs must have over current protection; circuit breaker(s) or fuse(s) permitted. Over current protection devices must have a DC voltage rating equal or greater than the nominal pack voltage current rating of protection device must be lower than the short circuit current that the pack can produce without damage each battery sub-pack that is in a distinctly different location must have its own over current protection

Master Cutoff

The switches described in 7.B.2.1 and 7.B.2.2 must disconnect traction battery pack
