How to Calculate the time of Charging and Discharging of battery?

You also need to keep in mind that a battery is not supposed to be "fully" discharged. Typically, a battery is considered "discharged" when it looses 1/3 of its capacity, therefore it only needs 1/3 of its capacity to be fully charged (range of operation). With these constraints and the above values, one gets only one answer, t = 33Ah/10A = 3.3hr

6 FAQs about [What is the approximate capacity of the battery pack ]

How much does a battery pack weigh?

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.

How much energy does a battery pack use?

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.

What determines the operating voltage of a battery pack?

The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.

What is the difference between battery capacity and chemical capacity?
