The application characteristics of batteries primarily include temperature, charging time, charging capacity, energy consumption, and efficiency. The MSCC charging strategy effectively prevents overheating of the battery during the charging process by controlling the charging current.
Charge acceptance is the willingness of a battery or cell to accept a charge. This is affected by cell temperature, charge rate, and the state of charge. Nihal Kularatna, Kosala Gunawardane, in Energy Storage Devices for Renewable Energy-Based Systems (Second Edition), 2021 Charge acceptance is the willingness of a battery or cell to accept charge.
The various parameters such as ensuring battery full-service life, temperature rise, and gas evolution during charge, state of charge (SOC), charging efficiency in AH and WH, and charging time are to be considered when designing a battery charger.
In multi-cell batteries another factor may be involved. The charge acceptance of any given cell in the series string may seem reduced if the battery pack is charged with a constant-voltage charger set at a low voltage. Under this condition, one cell in a battery may have a slightly lower charge acceptance than the other cells.
Whenever a battery's state-of-charge (SoC) is low, charging it is most efficient. Whenever the battery reaches a SoC of 70% or above, charge acceptance diminishes. When a fully charged battery becomes unable to convert electric energy into chemical energy, the charge should be reduced to a trickle or the battery should be shut down.
Charge-acceptance is the ability of a battery to accept and store energy under given external parameters like time, temperature, state-of-charge, charging voltage or battery history.
