Patent ID: 7816042

Claim:
An actively controlled battery with a programmed-timing actuation capability, said battery comprising: (a) a first metal-air cell assembly and at least a second metal-air cell assembly electronically connected in parallel, wherein said first cell assembly comprises at least a first metal-air cell comprising an active anode enclosed in an anode compartment, an air cathode, a first air access vent, a separator separating said anode from said cathode, a reservoir containing an electrolyte fluid therein, and a first controllable fluid valve being in flow communication with said electrolyte fluid reservoir on one side and in control relation to said anode compartment on another side; said first air access vent and said first fluid valve being closed during a battery storage period and being opened, at the first use of said battery, to admit outside air into said cathode and to allow an electrolyte fluid to enter said anode compartment to come in contact with said anode therein for activating an operation of said first metal-air cell assembly; and said second cell assembly comprises at least a second metal-air cell comprising a second active anode enclosed in a second anode compartment, a second air cathode, a second air access vent, a second separator separating said second anode from said second cathode, a second reservoir containing an electrolyte fluid therein, and a second controllable fluid valve being in flow communication with said second electrolyte fluid reservoir on one side and in control relation to said second anode compartment on another side; said second air vent and said second fluid valve being closed during a battery storage period and being opened in response to a programmed signal to admit outside air into said second cathode and to allow an electrolyte fluid to enter said second anode compartment to come in contact with said second anode therein for activating an operation of said second metal-air cell assembly; and (b) control means in control relation to at least said second cell assembly for sending programmed signals to open up at least said second air vent and said second controllable fluid valve in a programmed fashion.
