Adjustable input pulsation device
A battery pulsation system including a battery having a plurality of cells and a pulsation device connected to the battery to supply a pulsation energy to the plurality of cells, the pulsation energy having a pulsation amplitude and a pulsation frequency, wherein the pulsation device is adapted to control the pulsation amplitude of the pulsation energy.
1. A battery pulsation system comprising:
a battery having a plurality of cells, each of said plurality of cells having a cell open circuit voltage;
a pulsation device connected to said battery to supply a pulsation energy to said plurality of cells of said battery, said pulsation energy having a pulsation amplitude and a pulsation frequency; and
control circuitry configured to control said pulsation amplitude of said pulsation energy based upon a standard deviation value of said open circuit voltages,
wherein said control circuitry controls said pulsation amplitude of said pulsation energy based upon input signals received from a plurality of sensors, said input signals being indicative of said standard deviation value.
2. The system of claim 1 wherein said battery is a lead acid battery.
3. The system of claim 1 further comprising a battery charger connected to said battery, wherein said battery charger and said pulsation device are connected in parallel.
4. The system of claim 1 wherein said control circuitry controls said pulsation amplitude of said pulsation energy based upon input signals received from a plurality of sensors, said input signals being indicative of said standard deviation.
5. The system of claim 1 , wherein said plurality of sensors are voltage sensors connected to said plurality of cells of said battery and in communication with said control circuitry.
6. The system of claim 1 wherein said pulsation amplitude is increased when said standard deviation increases.
7. The system of claim 1 wherein said pulsation energy is directed to a select cell of said plurality of cells of said battery, said select cell having a larger voltage drop than the other cells of said plurality of cells.
