A stationary hybrid battery back-up system incorporates two different battery units that differ in terms of recharging efficiency, cycle life, power capability, depth of discharge threshold, temperature threshold, internal impedance threshold, charger rate efficiency and/or stand-by efficiency. The battery back-up system of the present invention comprises an auxiliary power supply that can be used to charge the first and second batteries and/or provide power to a load. When the operating voltage of the system drops, due to a power failure of a power source, the control system may couple the first and/or second battery unit to a load. The control system may have voltage threshold limits wherein it engages the first and second battery units to support the load demand. The first and second battery units may be charge by the auxiliary power supply when the operating voltage is above a threshold level.
A method for power storage in a power network, the method comprising:
A computer program product encoded on one or more non-transitory computer storage media, the computer program product comprising instructions that, when executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:
