  • Method and system for extending battery power at cell sites
    Patent number: 9419445
    Abstract: The embodiments herein provide a method and system for extending battery power at cell sites. The method for extending battery power at cell sites comprises providing a combination of a valve-regulated lead-acid (VRLA) battery and a Li-ION battery, mixing cell chemistry of the VRLA battery and the Li-ION battery and charging the VRLA-Li-ION battery combination with a single charger circuit. The method further comprises providing a rectifier to both the VRLA battery and the Li-ION battery and activating each battery based on the available power. The Li-ION battery and the VRLA battery are the primary battery and secondary battery. The charging current through the VRLA battery is regulated by varying a pulse width of a high current switch based on the current read through the current sensor attached to a VRLA current path.
