Charging is the process of replenishing electrical energy in a rechargeable battery by reversing the electrochemical reactions that occur during discharge. In lithium-ion and other modern battery chemistries, this involves moving lithium ions from the cathode back to the anode via the electrolyte, while electrons travel through an external circuit.
Factors Influencing Charging Performance:
Ambient temperature
Battery health and age
Internal resistance
Cell balancing requirements
Charging infrastructure (AC vs. DC, power limits)
