Ok, this is what i have, what do people think, what would they like me to add or remove.
Edited bits in italics
Ammended to read:
3.1
Only rechargeable NiCd, NiMH cells rated at 1.2
volts nominal will be allowed at BRCA sanctioned
events. The size of the individual cell(s) to be:-
Diameter: 23.0mm +0/-1mm
Overall length: 43.0mm +0/-1.5mm
Measurements include original manufacturers
heat-shrink. Overall length is the maximum
length before attaching/soldering any link wires
or battery bars. Dimensions taken at ambient
temperature, and apply to new/unused cells as
submitted by the manufacturer. Cells must never
exceed 44.0 mm length after any ‘matching’ or
charging processes. All cells must have the original
manufacturer’s heatshrink substantially
intact. Weights of submitted samples will be
recorded to verify that production versions compare.
From 2008 onwards, it is intended to
amend the rule that cells must never exceed
43.0mm (including any distortion from charging).
Lithium Polymer battery packs may be used to power electric racing cars if a Certification
Of Compliance has been received and accepted by BRCA from the manufacturers of the
battery packs. The Certification of Compliance indicates that the Lithium Polymer cells
internal to the battery packs have been tested in accordance with UN T1-T8, the United
Nations Recommendations on the Transport of Dangerous Goods, Manual of Test and
Criteria (ST/SG/AC.10.11/Rev.4) and passed the acceptance criteria. Lithium Polymer
battery packs that do not have UN certification must pass the ROAR tests
and performed by the ROAR Li-Poly Test laboratory. Certification of Compliance to these
test requirements and acceptance criteria shall be provided by the Original Manufacturer
of the batteries. The Certification of Compliance will apply to all Lithium-Polymer products
from the Original Manufacturer and provided on a one time basis. The Certification of
Compliance can be sent directly to BRCA by the Original Manufacturer or supplied to
BRCA by the Value Added Manufacturer that distributes the batteries. A Value Added
Manufacturer must also provide BRCA a Statement of Origin identifying the Original
Manufacturer of the cells used in the battery pack and the number of battery packs
provided for sale within the United kingdom. The Value Added Manufacturer performs the
assembly of cells into battery packs, installs the hard protective case and provides the
electrical hook up points. The Original Manufacturer is the manufacturer of the individual
cells.
Li-Poly battery packs must have a hard, protective case that surrounds the cell(s) in
the racing application. A factory encased hard shell pack is mandated for race
durability reasons that stem from the vulnerability of Lipo cells to physical damage.
Any physical distortion, denting or puncture to the cells will cause either an immediate
or long term safety risk. A hard cased pack reduces this risk significantly by protecting
the cells from crash damage, battery ejection, and general wear and tear at the track.
ROAR defines the "hard case" as a case made of ABS or similar type material. The
case shall consist of two (2) halves with each half being constructed from a single
mould that is not easily pliable and retains it shape without any exterior or interior
support. Both the top and bottom sections of the case must be secured together by
glue, double-sided tape or heat seal with a label across the seam stating "ROAR
Approved" in such a manner that separation of the case to remove or replace the cells
will destroy the case and/or label and render it unusable in competition. The case
must be installed by the manufacturer or Value added manufacturer no end User
installed cases are acceptable. The case will protect the cells from damage on all
sides and will completely cover all cells having only openings for wire connections.
Any modification to the factory approved hard case will make the pack ineligible for
participation in BRCA events.
Note: Approved batteries will be required to have "ROAR Approved" Label
across the seam by Jan 2009. ROAR will have a grandfather clause until Jan
2009 for all approved cells at competition on the Label rule.
The maximum case size shall be as follows:
Length: 139mm +0mm/-3mm
Width: 47mm +0mm/-2mm
Height: 25.1mm +0mm/-3.0mm
All rechargeable batteries must meet BRCA
specifications before they will be approved by
the BRCA Electric Board. Details of newly
approved rechargeable batteries will be published
on the BRCA website. Only batteries
appearing on the official BRCA website homologation
list published in January will be legal for
use at BRCA sanctioned events from 1st.April
of that calendar year.
As you can see i have kept it fairly simple for the BRCA, if we follow the ROAR rules then it will save the BRCA (PW i assume) a lot of time and headaches testing the lipo cells.
If anyone thinks this should be ammended in any way let me know, once we have the BRCA one sorted i will transpose brca for EFRA and get that one done too. We dont want to be buying new cells for the euros
