Abstract

A housing for a battery cell, preferably for a lithium-ion cell, includes a housing cover, and a metal-core printed circuit board on the housing cover. The housing further includes an electronic component that is configured to monitor the battery cell, and that is arranged on the metal-core printed circuit board on the housing cover. This configuration enables the temperature of the battery cell to be very precisely and cost-effectively determined by very good thermal coupling to the housing cover. The disclosure further relates to a battery cell, a battery module and a vehicle.
