6 FAQs about [Research on charging and discharging loss of energy storage equipment]
Are EV battery losses localized in EV charging and discharging?
The results presented in section 4 show that losses are highly localized whether in EV charging or in GIV charging and discharging. Loss in the battery and in PEU depends on both current and battery SOC. Quantitatively, the PEU is responsible for the largest amount of loss, which varies widely based on the two aforementioned factors.
What is the difference between charging and discharging?
Generally, with some exceptions, percentage losses are higher at lower current, more consistently for charging than discharging. Some very high losses are found at low SOC (again, with exceptions). For charging, generally the higher efficiencies are achieved at higher SOC and higher current.
Why is the ratio between charge and discharge rates important?
This process indicates that the discharge current needs to be sufficiently high to counterbalance the overpotentials associated with charging and discharging. Thus, the ratio between charge and discharge rates is crucial, not their absolute values.
Why is state-of-charge estimation important?
Multiple requests from the same IP address are counted as one view. Exact state-of-charge estimation is necessary for every application related to energy storage systems to protect the battery from deep discharging and overcharging. This leads to an improvement in discharge efficiency and extends the battery lifecycle.
How does charge/discharge affect the cycle life of LMBS?
Full cell tests have revealed significant impacts of charge/discharge rates on the cycling life and CE of LMBs. With slow charge/fast discharge, the cells can reach over 1000 cycles, which is nearly 9 times higher than the cycling life under fast charge/slow discharge conditions.
What is the research gap in energy storage technologies?
With regards to energy storage technologies, exploring alternative materials for improved energy density, safety and sustainability exists as a huge research gap. The development of effective battery management systems for optimisation and control is yet to be fully exploited.
