Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but
The reusable battery PL was calculated at $234–278·MWh −1, whereas new battery power cost $211·MWh −1. They concluded that reusable batteries are not cost-effective although their initial costs are much lower. The new battery cost estimates from Steckel et al. were $151·kWh −1, and the one from Kamath et al. were $209·kWh −1.
State of charge (SoC) cell balancing is one of the most important roles of battery management systems (BMS). The performance and lifespan of a battery pack can be significantly degraded and reduced by the presence of imbalance in cells SoC. Recently, we have shown that using a machine learning driven battery pack reconfiguration technique based on a network of
The control strategy is mainly divided into two types: logic control and optimisation control. Logic control is to consider all possible inconsistencies in the battery pack, and artificially formulate the direction of energy flow in the equalisation circuit. For example, the widely used “peak shaving and valley filling” strategy.

The challenges in the designing or selection of cells for a new battery pack are addressed by the concept design process model. As already established in Table 3, the new battery pack needs to have energy density higher than 220 Wh/kg and two different GWP parameters as an example reference point for the new design.

The phase II of the proposed design process model takes into regard the additional parts of the battery pack and the aspects of thermal properties, life cycle of the battery pack and how is the pack subdivided into modules. It is an important aspect of battery pack and should be considered by any designer in the design process.
This marks the end of phase I of the conceptual battery pack design process. There are possibilities of multiple battery chemistries at the end, depending on several factors of cell form factor and other cell types. This fact is the reason why further calculations are necessary to be performed based on the phase II of the process model.
