Abstract: Certain embodiments are described that provide a method for measuring battery parameters under discharge/charge. (a) A battery at rest is provided having an initial State of Charge (SoC). (b) A discharge/charge excitation is applied for a first period of time. (c) The battery is allowed to rest for a second period of time. (d) A discharge/charge is applied, having a higher current and shorter duration than the discharge/charge of step (b). (e) The battery is allowed to rest for a third period of time. (f) Steps (b)-(d) are repeated. Parameters of the battery are measured during a plurality of the steps.
