English Abstract

A graphic state of battery charge indicator is used to provide the user with a visual indication of state of battery charge, magnitude of current flow and direction of current flow by using displays such as multi--segment LCD or LED displays in the shape of a battery. The indicator is able to provide these parameters by sequencing the on/off operation of the segmented displays. A microcontroller is provided battery state data from a battery monitor and converts this information to on/off commands for the segmented displays. There may be up to 10 segmented displays in the indicator with each segment proportionally representing a percentage of the state of battery charge. State of charge is indicated by a single on display at the appropriate location in the display. Current flowing into the battery is represented by a ripple effect in the displays in the positive direction. Current flowing out of the battery is represented by a ripple effect in the display in the negative direction.


French Abstract

Un état graphique dindicateur de charge pour une batterie est utilisé pour procurer à lutilisateur une indication visuelle de létat de charge de la batterie, de lampleur et de la direction de lécoulement de courant en utilisant des dispositifs daffichage tels des dispositifs daffichage ACL ou DEL multisegments dans la forme dune batterie. Lindicateur peut fournir ces paramètres en séquençant lopération marche/arrêt des dispositifs daffichage segmentés.


Note: Claims are shown in the official language in which they were submitted.

Claims
1. A multi-mode display for graphically displaying a state of charge and a
rate of charge for a
battery connected to at least one load and a battery charging system, wherein
said battery
charging system comprises at least one source of charging power, a
microcontroller for sensing
said state of charge and rate of charge, wherein said multi-mode display is
connected to said
microcontroller, and wherein the multi-mode display comprises a plurality of
horizontally
stacked display segments commencing at a lowest magnitude segment and ending
at a highest
magnitude segment for displaying a plurality of indications representing the
sensed state of
charge and rate of charge;
wherein said plurality of horizontally stacked display segments display a
positive ripple rate
from said lowest magnitude segment to said highest magnitude segment and a
negative ripple
rate from the highest magnitude segment to the lowest magnitude segment;
wherein said positive ripple rate is directly proportional to said rate of
charge.
2. The multi-mode display of claim 1, wherein each display segment of said
plurality of
horizontally stacked display segments has an enabled mode, a disabled mode and
a blinking
mode.
3. The display of claim 2, wherein the state of charge and rate of charge
comprise at least the
following:
i. a state of charge of the battery;
ii. a magnitude of said state of charge of the battery;
iii. a direction of current flow; and,
iv. a magnitude of said current flow.
4. The display of claim 3, wherein said state of charge of the battery and
said magnitude of the
state of charge of the battery are displayed.

5. The display of claim 3, wherein the state of charge of the battery, the
magnitude of the state
of charge of the battery and said direction of current flow are displayed.
6. The display of claim 3, wherein the state of charge of the battery, the
magnitude of the state
of charge of the battery, the direction of current flow and said magnitude of
current flow are
displayed.
7. The display of claim 3, wherein when the state of charge of the battery is
sensed at least one
display segment of said plurality of horizontally stacked display segments
will operate in said
enabled mode.
8. The display of claim 7, wherein when the magnitude of the state of charge
of the battery is
sensed a proportional number of the horizontally stacked display segments will
operate in the
enabled mode thereby displaying the state of charge and the magnitude of the
state of charge.
9. The display of claim 8, wherein when said direction of said current flow is
sensed the plurality
of horizontally stacked segments will operate in one of said positive ripple
mode and said
negative ripple mode the result being that the positive ripple mode indicates
a charging battery
and the negative ripple mode indicates a discharging battery.
10. The display of claim 9, wherein when said magnitude of the current flow is
sensed the
positive ripple mode and the negative ripple mode will assume said variable
ripple rate
proportional to the magnitude of current flow, the result being that said
ripple rate for a larger
current flow is faster than the ripple rate for a smaller current flow, and
the direction of current
flow and the magnitude of current flow are displayed.
11. The display of claim 10, wherein when the battery is discharged the
plurality of horizontally
stacked segments will operate in said disabled mode.
12. The display of claim 11, wherein the state of charge of the battery, the
magnitude of the
state of charge of the battery, the direction of the current flow and the
magnitude of the
current flow are displayed sequentially over a predetermined period of time,
and wherein
within said predetermined period of time the state of charge of the battery
and the magnitude

of the state of charge of the battery will be displayed for a longer period of
time than the
direction of the current flow and the magnitude of the current flow.
13. A method for a multi-mode simultaneous display of a state of charge and a
rate of charge of
a battery comprising the steps of:
i. displaying a plurality of horizontally stacked display segments having an
enabled mode, a
disabled mode, a blinking mode and a rippling mode having a rippling rate,
wherein a bottom
display segment represents a lower value and a top display segment represents
a higher value;
ii. sensing said state of charge and enabling at least said bottom display
segment;
iii. sensing a magnitude of the state of charge and enabling a proportional
number of
horizontally stacked display elements;
iii. sensing a direction of current flow and enabling said rippling mode in
the said direction of
current flow between the bottom display segment to said top display segment;
iv. sensing rate of charge and displaying said rippling rate directly
proportional to the sensing
rate of charge;
v. sensing a discharged battery and disabling the plurality of horizontally
stacked display
segments.
14. The method of claim 13, wherein when said step of sensing said direction
of current flow
includes the step of sensing said battery charging and enabling the rippling
mode from the
bottom display segment to the top display segment.
15. The method of claim 13, wherein the step of sensing the direction of
current flow includes
the step of sensing the battery discharging and enabling the rippling mode
from the top display
segment to the bottom display segment.
