Product Description

The battery holder for pouch cells allows the electrochemical characterisation of a variety of pouch cell types within the 231 mm x 229 mm contact area of the platform. Pouch cells exceeding these dimensions can of course also be connected and characterised, but the platform may have to be extended for this purpose.

The battery holder for pouch cells has an electrical contact for the two battery tabs of the pouch cell to be analysed within a minimum distance of 15 mm up to a maximum distance of 210 mm. The contact surface of the contact tabs is 100 mm x 20 mm per contact. The thickness of the contact tabs of the pouch cell to be analysed must not exceed 2 mm.

Each of the two pouch cell contacts has two contacts insulated from each other for independent recording of the current and measurement of the voltage. This ensures reproducible contacting and the avoidance of measurement errors due to contact resistance. The design of the current-carrying contacts and the underlying circuit board is designed for up to 30 A so that the Reference 3000 (AE) incl. Reference 30k booster can also be used with the battery holder for pouch cells.

The standard cell cable from Gamry Instruments with its 4 mm banana plugs has corresponding sockets on the battery holder for pouch cells as well as a double socket for connecting the Reference test lead. You can choose between the 2 mm pin or the 4 mm socket and insulate the 2 mm pin with a rubber cap when using the 4 mm socket.

The current-carrying test leads can either be configured on the battery holder for pouch cells using the standard cell cable from Gamry Instruments with 4 mm banana plugs or, if required for higher currents up to 30 A, fixed to the two 8 mm threaded glands using the power cable of the Reference 30k booster.

A 35 A automotive fuse provides protection in the event of accidental short circuits and protects the battery from a short circuit. However, low capacity batteries cannot be protected against explosion or fire in the event of a short circuit with currents below 35 A.
