Parallel Connection: Increases the battery pack’s capacity, essential for storing the energy required to achieve the desired range. To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh).
Increasing or decreasing the number of cells in parallel changes the total energy by 96 x 3.6V x 50Ah = 17,280Wh. As the pack size increases the rate at which it will be charged and discharged will increase. In order to manage and limit the maximum current the battery pack voltage will increase.
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.
To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh). The diagram below shows the configuration of a battery module from the Audi Q8 e-tron 55.
This buffer is detracted from a battery pack’s total capacity to obtain what is known as the usable capacity, or its usable kilowatt-hours (kWh). The battery powering the 2023 Mini Cooper SE, currently the EV with the smallest battery pack available in the US, has a total or gross capacity of 32.6 kWh, but its usable capacity is 28.9 kWh.
Hence a 50kWh pack with a cell capable of delivering a 2C discharge rate will give approximately 100kW. However, this is a very rough approximation. Resistance of the cells, connections, busbars and HV distribution system will determine the power and energy capability of the pack.

Tesla LFP Model 3
The Tesla LFP Model 3 is quite a landmark battery pack for Tesla. Up until now everything has revolved around chasing the energy density of cylindrical cells from 18650 to 21700. The 4680 cylindrical is a move to a larger and lower cost cell. This move to Lithium Iron Phosphate (LFP) is perhaps more significant and triggered by the success of BYD and their …

You can immediately see that the high capacity 200Ah cell produces a minimum pack capacity ~138kWh at ~800V. The increments in pack capacity are also 138kWh. The small 5Ah cell allows a more granular approach to pack sizes, the downside is the number of cells that are used and hence the complexity of items such as the busbars.

Battery Pack Sizing
The usable energy (kWh) of the pack is fundamentally determined by: Energy (kWh) = S x P x Ah x V nom x SoC usable / 1000. Note: this is an approximation as the nominal voltage is dependent on the usable window. Also, the variation in cell capacity will be needed to be understood to establish accurate pack capacity values in production.

Electric Car Battery Replacement Cost Explained
We estimate that the price of the 64 kWh battery pack replacement costs about $10,000-$12,000 (though the current market price for a battery pack at that size is closer to $8,900). Labor will likely be similar at around $600-$1,000 for 3-5 hours of work. Note: with the massive battery recall back in 2021 (for model years 2019-2020), KONA Electrics should all …
