Such electrical energy may then be “reused” by the charging circuitry or system and/or in the system powered by the battery/cell and/or external to the charging circuitry or battery/cell. The energy output and/or generated by the battery/cell in response to discharge signals of a charging sequence/operation may (1) supply energy to the associated system being powered by the battery, (2) supply charge current to the same battery/cell or another battery/cell, (3) supply charge to one or more cells in a multiple cell battery pack that are at a lower voltage than the other cells, (4) store the charge in a different charge storing device (e.g., a capacitor and/or second battery), and/or (5) heat a battery/cell to improve charging performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and circuitry to recover energy from discharge signals of a charging operation of a battery/cell","description":"Circuitry and methods to “capture”, recover, store and/or use electrical energy output and/or generated by the battery/cell as discharge signals of a charging sequence/operation.
