Abstract

A battery module (170) is presented. The battery module comprises multiple battery cells (110), and multiple connections (120) to at least one electrically sensitive circuit (130). Each of the multiple connections (120) comprises at least one component (121, 122) coupled in series between a battery cell (110) and an electrically sensitive circuit (130), the at least one component (121, 122) having an enhanced inductance (L) preventing a transient electric energy (141) to propagate from the battery module (170) to the electrically sensitive circuit (130), thereby redirecting the transient electric energy (142) to the multiple battery cells (110). Each one of the multiple battery cells (110) is configured to comprise an internal resistance (111) which is utilized for dissipating a portion (143) of the transient electric energy (142) being redirected to the battery cell (110). Hereby, the transient electric energy is safely dissipated by the multiple battery cells (110) of the battery module (170).
