The P-count determines the capacity of the pack in Amp-hours (Ah), and it also determines the amount of current the pack will be able to produce, measured in amps. For this example, we will use my favorite ebike cell, the Samsung 30Q. It is factory-rated as having 3000-mAh (milli-Amp-hours), which is the same as 3-Amp-hours (3-Ah).
More requirements for future battery generations are derived from government regulations and directions on energy efficiency, safety, and recycling, as FEV shows in the following. Cars, vans, buses, and trucks account for more than 20 % of global human-induced CO 2 emissions.

the probability of failure of the battery pack itself. Design elements that can be optimised readily to achieve the required level of protection without much impact on available resources are called control factors [22]. Some of the most critical control factors of an EV battery pack are: battery cells and cell spacer type, number
3 · The red circles show data from 5 electric vehicle battery busbars. The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2.. The gradient of the "straight line fit" shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing …
