How can energy storage systems reduce charging congestion and charging cost?

In practice, one of the efficient ways to mitigate charging congestion and charging cost of fast charging is applying energy storage systems (ESSs) which are generally installed at FCSs (Ding et al., 2015). Any ESS device consists of one battery with a fixed capacity and one ESS charger.

Can energy storage systems solve the fast-charging scheduling problem?

To fill the gaps, this work introduces energy storage systems (ESSs) into the BEB fast-charging scheduling problem. A stochastic programming model considering uncertain discharge efficiencies of ESSs is established, aiming to minimize total operation costs of fast charging stations.

Does battery discharge rate affect internal resistance?

For a variety of BTM technologies, the battery’s internal resistance always plays a critical role in the heat generation rate of the battery. Many factors (temperature, SOC and discharge rate) impact on the internal resistance, however, scant research has explored the effect of battery discharge rate on the internal resistance.

What is the relationship between charging internal resistance and discharging internal resistance?

Doh et al. (2019) used intermittent current transient technology to obtain the internal resistance at different temperatures and SOC, and he established a sixth-order polynomial function relationship between charging internal resistance and discharging internal resistance at temperatures of 298K, 313K and 328K with SOC as independent variables.

What is the internal resistance of a battery if SOC is 0.1?

Moreover, when SOC is 0.1, the internal resistance is 130 m Ω at 5 °C, and the internal resistance is 63 m Ω at 45 °C. The deviation between the two measured values is around 70 m Ω, the lower the battery ambient temperature, the greater the internal resistance value. This finding is consistent with Yang’s study (Lai et al., 2019).

How does SoC affect the internal resistance of a lithium ion battery?

However, the SOC has a higher influence on the internal resistance under low temperatures, because SOC affects the resistance value of the battery by influencing the disassembly and embedding speed of lithium ions in anode and cathode as well as the viscosity of electrolyte (Ahmed et al., 2015).
