A battery management system (BMS) is needed for the use of Li-Ion cells. The BMS is indispensable because Li-Ion cells can be dangerous. If overcharged, they can undergo thermal runaway and explode. If overly discharged, chemical reactions take place within the cell that permanently affect its ability to hold charge.

An actual practical energy storage battery pack (8.8 kWh, consisting of 32 single prismatic cells with aluminum packages) was used as the test sample, as shown in Fig. 1 (a). A cut single battery cell, battery-like fillers and the original package were assembled to carry on the experiments, rather than based on a whole battery pack,

The cycling is performed at the maximal regime of the pack i.e. 30 A (pack specifications are given in the battery pack section) with ModuloBat (MB) technique (Fig. 4) between 42.5 V and 37.0 V. Each cycle is followed by one EIS measurement in galvanostatic mode (GEIS, Fig. 5) [5].

During peak energy demand, critical transmission infrastructure capacity hits its limit and electrons get jammed up like cars on a freeway during rush hour traffic We have plenty of space to construct new power plants but connecting it to the grid to move the power to where it is needed will be pricey
