This study introduces a modeling approach for the transient response of batteries against fast-front impulse currents. An experimental methodology is presented to allow time-domain simulation of the surge performance of the battery using a straightforward process that involves mathematical analysis of the experimental records. A lithium iron phosphate battery was used as a case study;the voltage across the battery terminals and the current flowing through them is recorded for a range of 0.1 to 5 kA generated through a combination wave generator (12 kV 1.2/50 μs, 6 kA 8/20 μs). The developed non-linear equivalent circuit model yields results in very good agreement with experimental data of standard and non-standard impulse currents with a wavefront duration longer than 3 μs and time-to-half up to 60 μs. This work provides an advanced framework for surge protection of battery systems contributing to reliability and resilience of modern power grids against lightning events and electromagnetic pulses.

We consider word-of-mouth social learning involving
$m$
Kalman filter agents that operate sequentially. The first Kalman filter receives the raw observations, while each subsequent Kalman filter receives a noisy measurement of the conditional mean of the previous Kalman filter. The prior is updated by the m-th Kalman filter. When
$m=2$
, and the observations are noisy measurements of a Gaussian random variable, the covariance goes to zero as
$k^{-1/3}$
for
$k$
observations, instead of
$O(k^{-1})$
in the standard Kalman filter. In this paper we prove that for
$m$
agents, the covariance decreases to zero as
$k^{-(2^{m}-1)}$
, i.e, the learning slows down exponentially with the number of agents. We also show that by artificially weighing the prior at each time, the learning rate can be made optimal as
$k^{-1}$
. The implication is that in word-of-mouth social learning, artificially re-weighing the prior can yield the optimal learning rate.
