Class 320
ELECTRICITY: BATTERY OR CAPACITOR CHARGING OR DISCHARGING
Class Definition:
Where a term, phrase, or derivation thereof appears in
italics in this class definition, that term or phrase is
defined in the Glossary, below. Use of such italics may be
limited to once per sentence or paragraph for better
readability.
GENERAL STATEMENT OF CLASS SUBJECT MATTER
This class provides for a method or apparatus for controlled
or regulated charging, discharging, or combined charging and
discharging of one or more voltaic cells, batteries, or
capacitors.
SCOPE OF CLASS
This is the residual class for subject matter relating to:
1. a method or apparatus for charging or electrically
rejuvenating (e.g., depolarizing, etc.) a voltaic cell,
battery, or electrical capacitor, wherein said charging or
rejuvenating is accomplished by controlled addition of
electrical energy into the cell, battery, or capacitor;
2. a method or apparatus for discharging a voltaic cell,
battery, or electrical capacitor, wherein discharging is
accomplished by controlled release of electrical energy from
the cell, battery, or capacitor into a nominal electrical
load, and further wherein the voltaic cell, battery,
capacitor, or combination thereof comprises the only source
of supply for the load;
3. a method or apparatus for combined charging and
discharging, whether or not the charging and discharging
occur simultaneously;
4. a method or apparatus for charging, discharging, or
combined charging and discharging, in combination with
subject matter auxiliary or appurtenant thereto for
measuring, testing, signalling or indicating a charge or
related condition of a cell, battery, capacitor, or operation
of a related charge or discharge circuit with respect to a
charging or discharging function or condition; or
5. a cell, battery, or capacitor structurally combined with
a generator or electrical converter, whether or not
electrical interconnection therebetween is recited.
(1) Note. The term "capacitor" has replaced the archaic term
"condenser" used in previous definition(s) of this class.
However, these terms are to be interpreted herein as being
interchangeable and therefor synonymous in scope and breadth,
irrespective of the modern accepted interpretation of the
term "condenser." See Glossary, below.
(2) Note. This class provides for charging or discharging of
a plural battery or capacitor arrangement (e.g., battery
pack, etc.), with or without a controlled generator. However,
charging or discharging of a single battery or capacitor with
a controlled generator is classified elsewhere. See
References to Other Classes, below.
(3) Note. This class provides for a charging circuit where a
cell, battery, or capacitor forms the only intended useful
load for the circuit. Where a load diverse from a cell,
battery, or capacitor to be charged is recited, or where
there is recited an additional circuit having utility outside
of this class, original classification is outside of this
class unless specifically provided for herein.
(4) Note. A nominal electrical load for receiving discharge
energy may be either a single load or a plural load that
functions or appears as a single load to a discharge circuit.
The load must be recited only by its electrical
characteristics (e.g., a D.C. load, a capacitive load, etc.),
and may also be recited as a nominal variable load. Unless
specifically provided for herein, original classification is
outside of this class where: (a) the recited load is
identified by its nonelectrical characteristics or its
particular-art purpose (e.g., electric motor, welding,
electrolysis, etc.); (b) plural loads function or appear to a
discharge circuit as other than a single or merely variable
electrical load; or (c) a source, other than a voltaic cell,
battery, capacitor, or combination thereof, is recited for
supplying the load, unless specifically provided for herein
(See (8) Note, below).
(5) Note. If an electrical load is disclosed as a battery or
a capacitor, then claimed recitation of the load as a
"battery," "capacitor," etc., is sufficient basis for
classification herein. If, however, the load is recited as an
"electric device," an "electric load," a "translation
device," etc., classification is based upon another
significant limitation and not on the basis of the disclosure
of the particular load device, unless there is no appropriate
place for the classification elsewhere.
(6) Note. If a supply source for a single load is disclosed
as a battery or capacitor and the load is not specified or
limited to a particular art, claimed recitation of the source
as a "battery" or "capacitor" is sufficient basis for
classification herein. However, classification of the same is
elsewhere if the claimed recitation of the load is in general
terminology, e.g., "a source," "a source of emf," "a source
of voltage or current," etc., where proper classification is
based upon a limitation other than the claimed source.
(7) Note. A method or apparatus for manufacturing a battery,
capacitor, or part thereof is classified elsewhere (see
References to Other Classes, below), even if combined with
charging or discharging. However, an apparatus for charging
or discharging, per se, is classified in this class even if
an intended use is recited for charging or discharging, per
se, during, or as a subcombination of, a manufacturing
process. This should be contrasted with a method for charging
or discharging which is limited to being incident to
manufacture, which is excluded from this class and controls
classification when subject matter for this class is also
claimed.
(8) Note. Where there is a combination of charging and
discharging recited: (a) there may be one or more sources of
charge energy, which may include one or more cells,
batteries, or capacitors; (b) a cell, battery, or capacitor
to be charged may be the cell, battery, or capacitor to be
discharged; (c) a source of charge energy other than a cell,
battery or capacitor (hereinafter nonbattery source) may
supply a load or discharge circuit simultaneously with a
cell, battery, or capacitor to be discharged, except where:
(i) the cell, battery or capacitor to be discharged can
supply the load or discharge circuit only when the nonbattery
source is connected to supply the load or discharge circuit;
(ii) the nonbattery source can energize the load or discharge
circuit without the cell, battery, or capacitor to be
discharged.
(9) Note. Where no subclass specifically provides for a
method appropriate for this class, classification is proper
in a subclass that provides for a device to practice the
method.

GLOSSARY:
BATTERY
A unit source of D.C. voltage consisting of a plurality of
voltaic cells electrically connected in series, parallel, or
both, to increase available voltage or power from a single
cell. "Plural batteries" include a combination or association
of two or more structurally dependent, or independent,
battery units.
CAPACITOR
An electrical energy storage device consisting essentially of
two electrically conductive surfaces (e.g., plates,
electrodes, etc.) separated by an insulator or dielectric
(e.g., air, paper, mica glass, plastic, oil, etc.), whereby
an electric charge, in the form of a direct voltage between
said conductive surfaces, can be either stored on said
surfaces or released therefrom to a load. "Plural capacitors"
include a combination or association of two or more
structurally dependent, or independent, capacitor units.
CELL
Short for, or used interchangeably with, a voltaic cell only
in this class.
CHARGE: BATTERY OR CELL
The act of adding electrical energy (e.g., supplying current,
etc.) into a battery or cell from a diverse source of
electrical energy to increase the amount of useful and
available chemical energy stored in the battery or cell; or,
the amount of chemical energy stored in a battery or cell
that is available for useful conversion to electrical energy
for supplying an electric load.
CHARGE: CAPACITOR
The act of applying an electric potential across the
electrodes or plates of a capacitor from a diverse source of
electrical energy to increase the amount of useful and
available electrical energy stored in the capacitor, or the
amount of energy stored in a capacitor that is available for
release to usefully supply electrical energy to an electric
load.
CHARGING CIRCUIT
The electric circuit or path that extends from a charging
source to a battery, cell, or capacitor to be charged.
CHARGING SOURCE
The immediate source from which electric energy is derived
for addition into a battery, cell, or capacitor, where the
polarity of the source is such as to cause current to flow in
opposition to the normal polarity of the battery, cell, or
capacitor, if the latter is polarized, and may be, for
example: (1) a mere charging circuit; (2) means for
collecting atmospheric, parasitic, or other stray electric
charge or currents; (3) means for converting electrical
energy having one or more particular electrical
characteristics into electrical energy having a different
characteristic (e.g., electrical converters such as a
combination alternating current source and rectifier, where
the rectifier is considered to be the "immediate source"; (4)
means for converting energy, other than electrical, into
electric energy (e.g., electrical generator, fuel cell,
etc.).
CHARGING SOURCE CONTROL
Any control that effects the flow of energy from a charging
source, including (a) direct control of the charging source
itself or (b) the flow or delivery of energy from the
charging source to a load.
CIRCUIT MAKING AND/OR BREAKING
Fully establishing and/or fully interrupting the conductivity
of an electrical path between two or more points in an
electrical circuit by physical movement of electrically
conductive elements into and out of physical contact with
each other.
CONDENSER
An obsolete or out-of-favor term for "capacitor." Although
still used in the automotive field to refer to a capacitor
used across ignition points to prevent arcing, it is
interpreted as being synonymous with "capacitor" in this
class, with no implied limitation to its use.
DEPOLARIZATION
The process of preserving or restoring a primary cell by
partially or completely removing its increased resistance
(i.e., polarization) as the potential of an electrode changes
during electrolysis.
DISCHARGE
The act of removing available electrical energy from storage
in a battery, cell, or capacitor via flow of electric current
from the battery or capacitor to a load.
DISCHARGE CIRCUIT
An electrical device or path which allows flow of electrical
current from a battery or capacitor to an electrical load,
especially that path or device that controls or regulates
said flow.
FUEL CELL
An electrochemical generator that uses the reaction of oxygen
and a hydrocarbon fuel, or derivative thereof (e.g.,
hydrogen, etc.), to convert chemical energy into electricity.
It is distinguishable from a voltaic cell because of its use
of a hydrocarbon for fuel, and because it can operate
continuously without a voltaic cell's inherent chemical
degradation of electrodes, as long as fuel and oxygen are
available or supplied.
LOAD, LOAD DEVICE, OR LOAD CIRCUIT
Any electrical device for usefully converting or consuming
electrical energy other than those devices which are merely
accessory, auxiliary, or appurtenant to the source and/or the
circuit which supplies electric energy. [An accessory or
auxiliary device is a device used to affect operation,
control, or care of a source and/or supply circuit and may,
for example, comprise a device employed: (i) to test,
indicate, or measure a condition of or in a source or supply
circuit, or (ii) to regulate or control the flow of electric
energy from or through the source or supply circuit.]
PRIMARY CELL OR BATTERY

usefully increased (i.e., recharged like a secondary cell) by
an electric current passing through it after having been
discharged from a usefully charged condition (i.e., the
chemical reaction is not reversible). (See the definition of
Depolarization, above).
REGULATION
Control of one or more characteristics or conditions whereby
said characteristics or conditions can be maintained at some
predetermined value, or can be varied over a plurality of
values.
SECONDARY CELL OR BATTERY
A cell or battery that may have its available charge usefully
increased (i.e., recharged) by an electric current passing
through it after having been discharged from a usefully
charged condition (i.e., the chemical reaction is
reversible).
VOLTAIC CELL
An elementary unit source of electrical energy stored as
chemical energy, comprising two separated dissimilar
electrodes bridged by an electrolyte, wherein said unit
source produces a potential difference across said electrodes
in a chemical reaction involving said electrodes and
electrolyte that converts chemical energy into electrical
energy. [Synonymous with cell, but distinguished from a fuel
cell, in which the electrodes are not required to be
chemically involved in the primary reaction.]
