BatPaC is a battery pack tool that considers inputs from users on battery configuration and chemistry to provide relevant outputs, including battery power, energy, voltage, specific power/energy, weight, bill-of-materials, and associated manufacturing costs (Argonne, 2022; Knehr et al., 2022).
Battery capacity measures how much energy, in amp-hours (Ah), a battery can supply. It is how much energy can be stored and drawn from it. A battery rated 150Ah can give a current of 1A for 150 hours or 5A for 30 hours. A batteries capacity is a factor of the rate at which current is drawn from it. The faster the rate, the lower the capacity.
