Secure plug-in connections for modular battery storage
The new connector series from HARTING enables safe, error-free installations and fulfills all relevant UL standards.
The sustainable use of renewable energies such as wind or sun can only be achieved through energy storage modules, since these enable time-delayed, needs-based use. The use of connectors accelerates the build-up of energy storage modules using lithium-ion cells.
With its Han S® series, HARTING offers secure connection technology for modular battery storage systems. The compact and flexible housings accommodate contacts for currents up to 200 A and 1500 V. The series’ bulkhead housings can be flexibly rotated through 360 degrees, and the locking of hoods and housings, male and female contacts is intuitive.
Safe and error-free installation
The Han S® offers users plug-in connections for storage modules while providing maximum safety, since the design meets all technical requirements. The male contact for the battery module is designed to be finger safe and is equipped with a screw contour with an M8 thread. The contact can be installed on the battery module in a user-friendly manner with a socket spanner. The socket contact is crimped onto the cable and then inserted and screwed into the sleeve housing without tools.
Time savings in service and maintenance
There is a red variant of the Han® S for the positive terminal and a black variant for the negative terminal. Both are also mechanically coded to prevent incorrect insertion. These properties are also beneficial for service and maintenance. If a cell in an energy storage module shows a drop in performance, the respective management system can be used to switch it off and have it replaced. To do so, the Han S® interfaces of the adjacent modules are simply turned aside in the locked state to make room for the switch-out. There is no need to interrupt the energy storage functions of unaffected modules.
Compliance with all relevant UL standards
Han S® is the first special high-current battery connector that meets the relevant UL and railway standards for stationary energy storage systems. Among others, it fulfils the requirements of UL 4128 for connectors in electrochemical battery system applications, UL 1973 for batteries in stationary applications, for emergency power supply for vehicles and in light rail applications, and UL 9540 for energy storage systems and accessories. Han S® is also shock and vibration proof according to the relevant railway standards.
A battery management module (BMS) is located in each modular storage module or storage cabinet. These units also need to be connected to form a control train. Here, the HARTING Han S® has added a bulkhead mounted housing with a busbar pin contact, once again in a red and black version. The system is managed via this train and the decentralized BMS transmit status messages to the higher-level system/plant control.
