AI Customer ServiceThe lithium-ion battery, which is used as a promising component of BESS that are intended to store and release energy, has a high energy density and a long energy cycle life .
Therefore, even if lithium-ion battery has a high CE, it may not be energy efficient. Energy efficiency, on the other hand, directly evaluates the ratio between the energy used during charging and the energy released during discharging, and is affected by various factors.
As an energy intermediary, lithium-ion batteries are used to store and release electric energy. An example of this would be a battery that is used as an energy storage device for renewable energy. The battery receives electricity generated by solar or wind power production equipment.
A battery may discharge at a steady load of, say, 0.2C as in a flashlight, but many applications demand momentary loads at double and triple the battery’s C-rating. GSM (Global System for Mobile Communications) for a mobile phone is such an example (Figure 4). GSM loads the battery with up to 2A at a pulse rate of 577 micro-seconds (μs).
At a 2C discharge, the battery exhibits far higher stress than at 1C, limiting the cycle count to about 450 before the capacity drops to half the level. The wear and tear of all batteries increases with higher loads. Power Cells are more robust than Energy Cells.
Discharging batteries at different depths can be achieved by using different cutoff voltages. When a battery is discharged to an extended depth, more energy is released during a single discharge cycle.
