At a regular warehouse operation, an electric forklift is designed to use one charged battery per 8 hour shift, with a normal battery charger capacity of one full charge every 8 hours and cooling (disconnected) time of 8 hours (in the S-BAS system, these times are programmable, according to each battery's specified requirements).

[0126] At a standard installation, as illustrated in FIG. 8, a battery charger station has one connector plugged to one battery under charge for 8 hours and one charged battery cooling down. When a spent battery is removed from a forklift, it is connected to the battery charger, the newly charged battery is disconnected to cool off and the other battery charged, the cold battery which is charged is installed back in the forklift for the current shift service.

[0127] This traditional charging cycle is widely adopted in the industry to minimize handling in battery changes to once per shift, minimize equipment weight by design and the correct (and safe) utilization of the battery charger equipment and the current power technology. It is apparent that the traditional charging technique is not optimal for increased efficiency of battery charging techniques.

[0128] The S-BAS system is designed as an innovative and advantageous battery charging management system to increase efficiency of battery charging techniques. The S-BAS system is designed for new installations as well as a retrofit or addition to existing battery charging racks.

[0129] The S-BAS system uses a Monitor and Control Base 4 for running polling routines and displaying and storing data. This Monitor and Control Base 4 has reporting and database capabilities that are a good decision making tool.

[0130] In operation of the S-BAS system, each battery charger is dedicated to charge one spent battery every eight hours without manual starts or supervision of any kind, based on the charge qualities and parametric data of each battery that is connected to it. Each battery charger will be fitted with an internal module, a Charger Remote Control 1 as shown in FIG. 1, that will control battery charger connect or disconnect functions through monitoring from the Monitor and Control Base 4 of specific conditions of the various components of the present invention. The S-BAS system will also manage charge and cooling timing of batteries.

[0131] Each Charger Remote Control 1 and Battery Sensor 3, as shown in FIG. 3, will be polled to transmit status and identification, providing real time data of present battery condition, a feature which is necessary to identify the batteries as they are connected for charge cycle, but will also detect malfunctions in battery charging equipment, or a deficient battery charging service due to malfunctioning equipment.

[0132] The Monitor and Control Base 4 sees the data traffic and the power parameters of each component comprising the S-BAS system, and provides the on-off times for each battery charge. The operator will have choices of open bays to connect spent batteries and harvest cold batteries in accordance with well monitored times, but also the S-BAS system will monitor cycles and charge parameters, providing information such as misuse, premature equipment failure conditions, maintenance (battery wash, electrolyte refill) orders and usage statistics.

[0133] The Monitor and Control Base 4 has one interface, a touch screen monitor, inside a heavy duty enclosure, mounted on the battery extractor or on the charging rack itself. The Monitor and Control Base 4 connects to each Neuron 2, each Battery Sensor 3 and each battery charger's Charger Remote Control 1 connecting to these various system components by radio frequency, using internal radio modems in each system component.

[0134] At any time, operators will be able to request a battery charge or request the battery with the longest cooling time, the S-BAS system will point to the available open bay and provide a battery to retrieve.

[0135] Because the batteries remain plugged in, even in the cool off period, premature battery failure can be also detected by the S-BAS system.

[0136] The touch screen display in the Monitor and Control Base 4 will present the user with a menu to request a bay for a spent Cattery and to request a cold, charged battery; the Monitor and Control Base 4 will present the user the best choice and a list of technical data for the units in the exchange, plus an automated list of maintenance requirements with supervisory release, and also present this data and all charging system irregularities to a designated file in the connected network.

Interaction of Components

[0137] To fully disclose the interaction of the components of the Smart Battery Administration System (S-BAS), the following is a further disclosure of the functional interaction of the system components. The S-BAS system is comprised of the following components:

a) A remote control/monitor for each battery charger, coupled to its internal circuit, labeled Charger Remote Control 1, described more fully in FIG. 1.
b) An intelligent charge harness consisting of one or more power nodes or Neurons 2 per battery charger, the Neuron 2 illustrated in FIG. 2. In the case where an end user has one charger per each battery or one and one half battery, these Neurons 2 will not be required, only remote Charger Remote Control 1, Battery Sensor 3, and a Monitor and Control Station 4.
c) A Battery Sensor 3 per each battery, illustrated in FIG. 3.
d) One Monitor and Control Station 4, illustrated in FIG. 4.

[0138] Each of these S-BAS system components will be described more fully in the following descriptions:

a) Charger Remote Control 1, Illustrated in FIG. 1

[0139] A brief description of battery chargers will describe more clearly how the Charger Remote Control 1 of the present invention functions in the Smart Battery Administration System (S-BAS). The S-BAS system is designed to perform at new battery centers as well as a retrofit to older model battery chargers. The vast majority of modern battery chargers are provided with: [0140] 1) Fault Indicator (via a red light or digital display). Sometimes battery chargers detect lower than normal voltage on batteries and protect the circuit from high inrush current. Other faults may include additional features depending on the manufacturer. [0141] 2) Charging status (via a red/orange light or digital display), meaning that the battery is connected and is being charged. [0142] 3) Ready status that indicates that the battery has been charged and the battery charger has stopped charging. [0143] 4) Stop Charging button. This push button interrupts the charging cycle and is manually activated by an operator. [0144] 5) Equalize button. This push button starts the equalizing cycle feature of the battery charger, the battery must be plugged in order to activate this option. [0145] 6) Charge Start. Not all models include this feature, but some battery chargers require a start command in order to start charging the battery, which is still done by manually pressing a button or setting a timer.

[0146] To cover these battery charger functions, the S-BAS system is designed to have a Charger Remote Control 3 installed at the battery charger and be controlled and monitored by a Monitor and Control Station 4.

[0147] The S-BAS system has been designed to perform at new battery centers as well as a retrofit to older model battery chargers, where the Charge Start function is still done by manually pressing a button or setting a timer. To cover these functions, the S-BAS system is designed to have a Charger Remote Control 3 installed at the battery charger, and these remote controls communicate with the Monitor and Control Station 4 via radio frequency transmission.

b) Neuron 2, Illustrated in FIG. 2

[0148] Each Neuron 2 consists of a power input feeding from the battery charger (or from another primary Neuron 2); inside, the Neuron 2 module has a distribution network consisting of three solid state, high current relays, 24, 25, and 26, one for each output connector 27, connector 28, and connector 29. In series with the input connector 62, a current shunt 42 measures the current going thru the Neuron 2 circuit, as illustrated in FIG. 2. From the input connector 62 and each one of the output connectors, 27, 28, and 29, an insulated parasitic current draw feeds the universal regulator 65 that powers the programmable microcontroller 20 and RF Radio Modem 10 transceiver. The programmable microcontroller 20 effectively measures the voltage to and from each output connector 27, 28, and 29 and provides a connection status when polled form the Monitor and Control Station 4. In this way, each Neuron 2 can act independently to protect itself and the equipment, but also reports and obeys the connect and disconnect commands from the Monitor and Control Station 4 Console. With the triple output connectors 27, 28, and 29, there is always going to be a free output connector to connect a battery, or if the charge rack is fitted with rapid battery chargers, the Neuron 2 can feed a secondary rapid battery charger, one which adds battery capacity and even create a network of Neurons 2, where each battery can be addressed to a battery charger, even if is on top of an adjacent column.

[0149] The battery connectors 62, 27, 28, and 29 are universal; the input connector 62 goes directly to the battery charger, the output connectors 27, 28, and 29 go directly to batteries or to other Neurons 2. The installation is designed to be quickly adaptable to new battery systems or retrofit to older battery systems.

c) Battery Sensor 3, Illustrated in FIG. 3

[0150] Each battery is fitted with a Battery Sensor 3 that verifies electrical parameters and provides status when polled via radio frequency signals from a Monitor and Control Station 4 to RF Radio Modem 10 of the Battery Sensor 3, as shown in FIG. 3. In the case that a battery leaves the range of the Monitor and Control Station 4, the Battery Sensor 3 will remain drawing very low current until is polled again. If the battery does not report status at the programmed intervals, the Monitor and Control Station 4 will consider it missing from system monitoring and will report out a deviation notice.

[0151] Once a battery is connected to the S-BAS system, the Monitor and Control Station 4 verifies its serial number and remotely analyzes the electrical usage and new charge parameters through a Battery Sensor 3.

d) Monitor and Control Station 4, Illustrated in FIG. 4

[0152] The Monitor and Control Station 4 is the brain of the system and performs a sweep polling of all the registered system components and collects the status of each component. Because the Monitor and Control Station 4 specifies and knows exactly the electrical parameters of each system component, ordering the connection or disconnection of the Neuron's 2 relays as required by the program, and knows exactly the expected behavior of each device, noting deviations made by equipment malfunction or operator negligence.

[0153] All the RF Radio Modems 10 in the S-BAS system are transceivers, designed to listen first for a polling command then, if called, the Charger Remote Control 1 units will respond with the required data. The Monitor and Control Station 4 has a registry of all the monitored equipment.

[0154] As shown in FIG. 4 the Monitor and Control Station 4 utilizes a single board microcomputer 30 that controls all peripherals and provides a shared file on a network, where all the data, events and flags will be noted.

[0155] At any given time the operator will be able to request an available charging bay, the S-BAS system will assign it to a battery and will wait for the connection. At another time, the operator will request a charged battery. The S-BAS system will provide a battery in a First in First out basis. If batteries are required without completing the mandatory cooling time (which will be recognized by a premature disconnection); then the S-BAS system will require a supervisory override. Monitor and Control Station 4 will guide the operator to facilitate the tasks and if events that should take place never happen, it will provide a supervisory override to justify and note those events as well.

[0156] The S-BAS will collect and store information on a server. This information is key to monitor a healthy fleet, to maximize the equipment usage and durability.
