What is a Soh - SoC balancing control strategy for energy storage systems?
This paper primarily proposes an SOH - SOC balancing control strategy for energy storage systems based on the characteristics and patterns of battery ageing.
How does %SoC affect battery temperature?
During charging, as %SOC increases, the battery temperature rises due to ohmic heating (I 2 R losses), electrochemical polarization, and reduced charge acceptance efficiency at higher SOC levels, which result in greater conversion of electrical energy to heat.
How does the SoH of a battery affect its internal parameters?
The SOH of a battery is closely related to the changes in its internal parameters. Through experiments on the hybrid pulse power characteristics (HPPC) of batteries at different lifetimes, the values of these parameters under the current SOH could be obtained.
How can a low Soh battery improve energy storage?
According to the SOH evaluation, the energy storage of the BESS will be significantly improved if some cells or modules with lower SOH are replaced. In the condition of the unknown SOH of battery, the relative aging degree of battery can be obtained by grading the H value on ICA or PDF curves based on actual charging voltage data.
