To realize the efficient use of battery residual energy, this paper attempts to estimate both the state of energy (SoE) and the state of available power (SoAP) for li-ion battery packs. First, the parameters of a 1st-order equivalent circuit model are identified online where the charging and discharging resistances are separately modeled.
Estimates of energy use for lithium-ion (Li-ion) battery cell manufacturing show substantial variation, contributing to disagreements regarding the environmental benefits of large-scale deployment of electric mobility and other battery applications.
Based on public data on two different Li-ion battery manufacturing facilities, and adjusted results from a previous study, the most reasonable assumptions for the energy usage for manufacturing Li-ion battery cells appears to be 50–65 kWh of electricity per kWh of battery capacity.
Lithium-ion batteries, prevalent in electric vehicles and portable electronics, have a different approach to kWh calculation. The formula takes into account the nominal voltage and ampere-hours (Ah): markdown kWh = Voltage x Capacity (in Ah) Understanding these variations ensures precise calculations tailored to specific battery types.
... It is estimated that producing one ton of lithium-ion requires 1,900 tons of water . In addition to the reduction of CO2 emissions that are associated with the battery production in general .

As Ellingsen et al (2014) has used data from an actual battery plant in order to evaluate the energy consumption we have chosen this number, 586MJ electricity per kWh battery, to perform an overview of the impact of production location on greenhouse gas emissions.
All other steps consumed less than 2 kWh/kWh of battery cell capacity. The total amount of energy consumed during battery cell production was 41.48 kWh/kWh of battery cell capacity produced. Of this demand, 52% (21.38 kWh/kWh of battery cell capacity) was required as natural gas for drying and the drying rooms.
