CHARGING STATIONS FOR ELECTRIC VEHICLES

POSTES DE RECHARGE POUR VEHICULES ELECTRIQUES

English Abstract

The main reason of the lack of success of EV projects was the
unability of the vehicle to get back in motion before those
long hours of recharging after their batteries have drained
out. This invention of mine is a modest try to encourage the
auto makers to make a move towards building pollution free
vehicles and gradually retire the internal combustion engine
ones.

Claims

CLAIMS:
The embodiments of the invention in which an exclusive
property or privilege is claimed are defined as follows:
1) A pillar-like connector that optionally and automatically
adjusts its height and depth that serves as an electricity
dispenser for charging batteries of EVs. (electric vehicles),
as well as parking meters for internal combustion motor
vehicles. This device can also be spaced in rows to serve
many vehicles at the same time in case of modular convoy
system and could also be built in walls or any other surface.
2) A manned, semi or fully automated station for charging
battery containers or "power packs" where the vehicles will
park at a loading bay. in case of front gate automobiles, an

Description

CA 02274370 1999-OS-31
SPECIFICATIONS:
A pillar-like electricity dispenser that electronically or
coin operated controls the billing and other functions of the
device. It can also replace the existing parking meters as it
can also take care of this kind of metering and subsequent
billing.
A manned, semi or fully automated stations for charging
"power packs" where the vehicles will park at a loading bay,
a conveyor shaft will approach taking along a supporting
plate that has the rail attached that will guide the power
pack out from the inside the body of the vehicle to the
inside the compartment of the charging station, and vice
versa. In case of automobiles a device will come up from the
ground and grasp the front panel that also serve as entering
steps, and move~'~out and ups out of the way of the moving power
pack, and returns to its original position right after the
freshly charged one are secured in place. This device doesn't
function in case of other vehicles or trailers. The station
will have also a mechanical device to take the pack out of
the vehicle and deliver to the conveyor car that circulates

back and forth, up an down and collects and delivers packs to
their compartments placed in many levels to save time of
operation. Some or all the compartments could have a rack
full of probe tubes that penetrates and service the batteries
whenever in need distilled water, etc, as well as make the
readings of their working status, reporting to a tag that
could be scanned and monitored at any time.
Fig.l Is the pillar type electricity dispenser that, as the
vehicle parks right besides, will move part (C) outwards
penetrating the electric contacts (A) in the vehicle's take
up contacts and dispense electricity as soon as the driver
makes the proper commands in the other side's panel. This
energy will travel from inner cables and through the flexible
cables (B). Motor (D) drives wheels (E) that will drive the
chain that will move the part (C) in and out. Motor (F) will
drive the shaft (Fl) up and down in order to align the
"nozzle" with the vehicle's take-up contacts. An inside
sensor controls the height of the "nozzle" and one onboard
controls the position of the vehicle and the charger making
the "fine-tune" driving.
Fig.2 is the device that will take the front panel of the
automobiles out of the way of the power packs and bring it
back right after the freshly charged one is back. (A) is a
tray that would come up from the underground making the
sticks (D) penetrate the holes of the panel to make it firm
to travel. Then the wheels (E) will roll away from the
vehicle at the same time triggering the elevator (B)
counteracting by the weights (C) moving together until find a
proper place atop the next machine.
Fig.3 Is a conveyor that acted by chain system illustrated in
(E) will make the shaft (C) move outwards making the plate
(A) penetrate the female holders of the vehicle and activate
the locking pin that penetrates the hole (B) and making the
plates (D) to engage the power pack holders to the (C) shaft.
After this is done, the system of the wheels (E) will work
the oposite way bringing the power pack out of the vehicle
and move towards the charging station. After certain point
the conveyor shaft will come to the end of the rope and the
"pack" is still far away from the next stage. Then the
conveyor shaft system will move upwards to the position (F)
and the wheels (Fl), forced upwards by the springs (I) will
come into action delivering the "pack" to the shaft of the
conveyor car that will take care of the rest of the trip.
Fig.4 is an inside view of the charging station showing at
the center the conveyor car that acted by the system (C) will
penetrate the shaft (A) into the holders of the "pack", will
release the plates (B) and will drag it from the previous
stage its center, then will move forwards or backwards,
straight or upwards to deliver the load to the charging
compartments (Fl). This same, or other similar cars, if
available, will make other pick-ups and deliveries in both

sides. Systems driven by wheels (I) and counter weighed by the
pads (K) will make the rails (M) go up and down, thus
elevating the power packs to desired level. Wheels (F)
rolling on rails (G) will provide back and forth movement for
the conveyor car, In case additional operation requires it to
move sideways, locks (L) should be released and wheels (E)
will make the car to move right or left. All these operations
could be manned, semi or fully automated.
Fig. 5 is a probe tube that coming down from the ceiling area
of the charging compartments, penetrates each battery cell
stopping just above their plates. The battery solution will
enter the vents (A) and sensor (E) will do the readings of
the level of solution and conditions of the cell,
transmitting the information to a tag located in some area of
the "pack" easy to be scanned. Should the solution is low,
the same tube will dispense necessary deistilled water or any
other chemicals to the battery cell. The wire (D) is what
connects the sensor (E) to the other side of the equipment.
Fig. 6 is the rack that will drive the above mentioned tubes,
all at the same time (B) one for each cell, that in order to
ensure perforation of all the battery caps at the same time,
would have some heavy beams at the frame (A). (D) would be
the cables or rods that will drive the whole rack up and
down, and (C) are the tubes and wires that will make the
possible the electronic readings as well as necessary fluid
dispensing.
Fig. 7 is a bird's eye view of a charging station where the
vehicles (E) will park, activate the pads (F) with a credit
card, punching a code, etc., will make the loading bay (A)
function and start the interchange session. (D) are the
charge compartments and (B) the conveyor cars that will roll
on rails (C).
