Abstract
A backup pump control unit can incorporate ports to receive rechargeable batteries such as lithium ion, nickel cadmium or nickel metal hydride batteries. Multiple units can be coupled together to increase the available, stored electrical energy. In the absence of AC-type input power, the batteries can energize a backup pump.
Claims26
A pump control system comprising:
- a battery recharging unit, the unit having a plurality of battery receiving ports, the ports are each configured to removably receive and recharge a predetermined rechargeable battery, where each port includes first and second battery engaging conductors with at least two of the first conductors in continuous electrical contact with one another, and with at least two of the second conductors in continuous electrical contact with one another;
- a pump connector;
- and
- circuitry coupled to the ports and the connector to couple electrical energy from one of, rechargeable batteries or a displaced electrical source, to the pump connector.
1 more element
An apparatus comprising:
- a plurality of separable battery recharging units, the units are electrically coupled together and each carries a plurality of battery recharging ports, at least one of the units carries a pump connector port, at least one of the units carries an AC-type input port to couple electrical energy from a displaced source to at least some of the recharging ports.
A pump control unit comprising:
- a housing;
- first and second pluralities of battery contacts carried by the housing where all contacts of a respective plurality are in continuous electrical contact with each other;
- first and second electrical ports carried by the housing where the first and second pluralities of contacts are continuously electrically connected to the ports;
- and
- a pump connector port switchably coupled to the first and second pluralities of contacts.
2 more elements
An apparatus comprising:
- a plurality of separate battery recharging units, each unit includes a housing having a plurality of battery recharging ports and two spaced apart connectors, at least one of the units carries a pump connector port, at least one of the units carries an AC-type input port to couple electrical energy from a displaced source to at least some of the recharging ports where the members of the plurality can be plugged together to provide one of increased output voltage at the pump connector port, or, increased available stored energy at the pump connector port.
