... Especially, lithium-ion battery packs for EVs consist of multiple cells in series, parallel, and series-parallel to satisfy enough energy and voltage requirements.
However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
A challenging problem in energy storage systems for electric vehicles (EVs) is the effective use of lithium multicell batteries. Because of production tolerances, unbalanced cells can be overstressed during usage, thus leading to the reduction of the available capacity and premature failure of the battery pack.
Each battery pack consists of 104 cells in series, with a nominal voltage of 374.4 V and a nominal capacity of 162 Ah. The data are sampled at the frequency of 1 Hz. In addition, SOC-OCV tables at different temperatures are provided, as shown in Fig. 2.
Lead-acid battery capacity sizing was performed in accordance with the Equation (4) of IEEE 485. where kt is the ratio of rated ampere-hour capacity of the cell, to the amperes that can be supplied by the cell for t minutes at 25 °C and to a given minimum cell voltage.
After a comprehensive review and comparison, the future prospective of onboard capacity estimation is also discussed. This paper aims to help design and choose a suitable capacity estimation method for BMS application, which can benefit the lifespan management of Li-ion batteries in EVs and RESs.
