The "Mismatch loss" is mainly due to the fact that in a string of modules (or cells), the lowest current drives the current of the whole string.Now when installing real modules in the field, the characteristics of each module are never rigorously identical. The parameters (Isc, Vco, Pmpp) usually present statistical distributions, which may be rather Gaussian, or with a square shape

I have been using smart batteries mostly to avoid power loss, but I was thinking since this is for power spine and they will be constantly in use and being filled, maybe the power loss will not be worth the effort of building lots of smart battery (not to mention the cost of refined metal for it).

System analysis Battery losses are due to several factors, among which are undesired electrochemical reactions within a battery, bad battery condition management by a battery management system (BMS), and cell warming due to internal resistance . Accounting for such losses from a theoretical point of view is beyond the scope of this paper.
The losses occurring in the battery and in the PEU are simultaneously assessed during the experiments. Each experiment consists of neutral amp-second round-trips applied at the DC bus level, or in other words, same number of coulombs are charged to and discharged from the battery.
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.
The simulation is based only on the battery and charger losses because only those are non-linear (except the large under-used transformer, which is rather unique to this building configuration). The initial battery SOCs are evenly distributed in the 20%–90% interval for all simulations in both algorithms.
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. In this section, engineering solutions for reducing losses are explored.
These previous studies supported this study's decision to vary SOC and current as parameters affecting battery internal losses. Regarding other EV components, the PEU losses consist of two parts: stand-by losses inherent in the electronics, and Joule effect losses proportional to the square current .
