AccuMotion extender battery system for PEMS applications

Battery system for PEMS applications in a robust case.

AccuMotion extender battery system for PEMS applications

The project consisted of the development and production of a battery system, according to customer-specific specifications, integrated in a robust case so that it remains particularly mobile, including all certifications and UN38.3 test as well as the necessary safety for applications of PEMS systems.

The special challenge was to develop a battery for indoor and outdoor use that meets the customer's high requirements and also remains very robust with high energy density and yet mobile for use. 

The well thought-out mounting system also shows how flexibly the AccuMotion Extender can be used.

All data from the battery system (state of charge, cycles, capacities, etc.) can be read out with the optionally available mobile handheld (battery readout device).
 

Research focus


Our goal was to develop a mobile battery system that is suitable for the ever-growing PEMS (Portable Emissions Measurement System) sector. The energy demand here is increasing due to the growing number of measuring devices, so it was necessary to develop a battery system that still has reserve capacity due to the additional measurements. 

We paid special attention to the integration of the battery packs, as the system can accommodate 1-4 7S13P lithium-ion battery packs, set in high-quality aluminium shells to provide increased fire protection. Due to the particularly flexible universal accommodation of1-4 battery packs, the AccuMotion Extender covers a wide range of applications.

The integration of the interface and the reading of up to 4 batteries simultaneously was a challenge that we mastered.
 

Our solution


AccuMotion Extender incl. 4x Lithium Ion AP7S13P high performance battery packs with approx. 37.7Ah each, total capacity over 150 Ah, total power approx.: 3905 Wh, in a high-quality robust case (case type: PELI 1520).

Designed with the highest quality and most modern safety standards, the specially developed electronics built into the battery protects the battery from overcharging, deep discharge, short circuit and is equipped with monitoring of the individual cells and temperature. The new battery pack Lithium-Ion AP7S13P, 25.2V / capacity 37700 mAh / is designed for a continuous load of 40A.

The batteries are enclosed in aluminium shells (offering increased fire safety) and are mounted vibration-proof and have a high-quality Lemo push-pull plug and protective cover. The plugs are approved for a continuous load of 72A (optionally 120A). An additional connector for interface communication enables monitoring of battery data, both for individual batteries and for the entire group.

The AccuMotion Extender has a safety on/off switch function as well as a side mounting rail for universal mounting options (e.g.: tensioning strap etc.). The flexible interior design allows 1-4 batteries to be fitted.
