Abstract: Example systems and techniques are described herein for maintaining a rechargeable battery packs. An example battery management system includes processing circuitry coupled to memory and a plurality of battery connectors. The processing circuitry is configured to determine a first number of rechargeable battery packs removably coupled to a respective battery connector that comprise a respective charged battery and to determine a second number of rechargeable battery packs removably coupled to a respective battery connector that are in a storage mode. The processing circuitry is configured to determine that the first number meets the charged battery threshold and determine that the second number does not meet the storage mode threshold. The processing circuitry is configured to, based at least in part on the first number meeting the charged battery threshold and the second number not meeting the storage mode threshold, place a rechargeable battery pack in the storage mode.

Abstract: At least one electrochemical cell is charged to a predetermined voltage of the electrochemical cell using an external power source. A charging current of the at least one electrochemical cell is monitored. An increase in the charging current is detected at the predetermined voltage of the at least one electrochemical cell. It is determined that the at least one electrochemical cell is in danger of experiencing a performance decrease based on the detected increase in the charging current.

Abstract: An electrochemical cell charging apparatus includes a charger to charge one or more electrochemical cells and a computing apparatus. The computing apparatus includes one or more processors and is operatively coupled to the charger. The computing apparatus is configured to charge an electrochemical cell using the charger, determine one or more indicators of the state of health of the electrochemical cell, and determine the state of health of the electrochemical cell based on the determined one or more indicators.

Abstract: An electrochemical cell includes a positive electrode. The positive electrode includes a first current collector and a first active material. A negative electrode includes a second current collector and a second active material. A separator is disposed between the positive electrode and the negative electrode. A silicon-based anti-corrosion coating is configured to at least partially coat one or both of the first current collector and the second current collector.
