OEM (Original Equipment
Manufacturer)
is a broad term whose meaning has
evolved over time. In the past, OEM
referred to the company that originally
built a given product, which was then
sold to other companies to rebrand and
resell. Over time, however, the term
is more frequently used to describe
those companies in the business of
rebranding a manufacturer‘s products
and selling them to end customers.
Battery
One or more electrochemical
cells electrically connected in
an appropriate series / parallel
arrangement to provide the required
operating voltage and current levels
including, if any, monitors, controls
and other ancillary components (fuses,
diodes), case, terminals and markings.
Cell
The basic electrochemical unit
providing a source of electrical energy
by direct conversion of chemical
energy. The cell consists of an
assembly of electrodes, separators,
electrolyte, container and terminals
Secondary battery
Battery that can be reused after it
is charged. There are Ni-Cd and Ni-
MH rechargeable carbon batteries in
addition to Li-Ion rechargeable battery.
Primary battery
is a battery that is designed to be used
once and discarded, and not recharged
with electricity and reused like a
secondary cell.
Separator
A microporous thin film inserted
between cathode and anode to prevent
short-circuits and maintain spacing.
Polyethylene film, polypropylene film,
or other film is used.
Cathode
An electrode at higher potential than
the anode, passing electric current to
the outside circuit during discharge.
Anode
An electrode at lower potential than
the cathode, into which current flows
from an external circuit during cell
discharge.
Glossary
COINPOWER | GLOSSARY
Open circuit voltage (OCV)
The voltage of the battery when it is
disconnected electrically from outside
circuits.
Closed circuit voltage (CCV)
The voltage of the battery when it is
connected electrically to an outside
circuit.
Nominal Capacity
Capacity used to represent a battery
capacity. Usually means capacity in
ampere hours, indicated by Ah or mAh.
Nominal Voltage
The nominal voltage of a battery is a
measure of the expected voltage of a
battery or cell over its entire discharge
cycle. The nominal voltage of Coin
Power is 3.7 V.
Cycle Life
The number of cycles under specified
conditions which are available from
a secondary battery before it fails
to meet specified criteria as to
performance.
