Abstract: The present disclosure relates to an auxiliary device for monitoring a module and/or pack of an electric battery system. The auxiliary device provides module-level and/or pack-level measurements and may be flexibly placed anywhere within an electric battery monitoring system.

Abstract: A pouch cell battery assembly is disclosed, comprising a pouch cell battery and an electronic device. The pouch cell battery comprises: an expandable enclosure, accommodating an anode stack, a cathode stack, and a separator disposed between the anode and cathode stacks; first and second contact terminals, the first contact terminal being electrically coupled to the anode stack and the second contact terminal being electrically coupled to the cathode stack. The electronic device may be at least partly affixed to the expandable enclosure, and electrically coupled to the first and second contact terminals. The electronic device may be configured to determine at least one physical characteristic of the pouch cell battery.

Abstract: A method of and processor for determining a position of a battery cell within a battery system comprising a plurality of battery cells, each battery cell having a unique identifier (ID) is provided. Each battery cell is configured to emit a first signal when in a first state, the first signal enabling the battery cell in the first state to be distinguished from the plurality of other battery cells comprised in the battery system. The method may comprise: receiving a first signal associated with a battery cell in the first state; obtaining the unique ID associated with the battery cell in the first state; determining the position of the battery cell in the first state within the battery system, based on the received first signal associated with the battery cell in the first state; and associating the determined position with the received unique ID of the battery cell in the first state.

Abstract: Methods and systems for determining a position of a battery cell within a battery system comprising a plurality of battery cells are disclosed. Each battery cell has a unique identifier, and each battery cell is configured to experience a change in voltage when an electrical stimulus is applied to the battery cell. The method comprises receiving a first signal associated with a first battery cell experiencing a change in voltage due to an electrical stimulus applied to the battery cell; obtaining the unique ID associated with the first battery cell; determining the position of the first battery cell, based on the received first signal associated with the first battery cell; and associating the determined position with the obtained unique ID of the first battery cell.

Abstract: An electric battery assembly is provided comprising: a battery cell having a positive terminal and a negative terminal; an electronic unit comprising a measurement device and a wireless transmitter; a support structure configured for attachment to the battery cell, and arranged to house the electronic unit, the support structure comprising at least one conducting element arranged to electrically couple the electronic unit to the positive and negative terminals, to thereby provide electrical power for the wireless transmitter and the measurement device; and wherein the measurement device is configured to measure a property of the battery cell, and the wireless transmitter is configured to wirelessly transmit the measured property.

Abstract: The present invention relates to a maturation process for at least one electric battery cell 32. The maturation process comprises charging the at least one electric battery cell 32 and subjecting the at least one electric battery cell to a maturation period of at least one day wherein no electrical load other than a measurement apparatus 30 is connected to the at least one electric battery cell. The maturation process also comprises taking at least one measurement of the open circuit voltage of the at least one electric battery cell 32 with the measurement apparatus 30 between the start and the end of the maturation period. The maturation process further comprises determining the integrity of the at least one electric battery cell in dependence on the at least one measurement.
