Storage of lithium-ion batteries at the motorbike manufacturer KTM
KTM AG, headquartered in Mattighofen, produces, develops and sells innovative off-road and street motorcycles of the KTM and Husqvarna Motorcycles brands that are suitable for racing. The globally active company has been on the road to success for years thanks to its constant management, highly qualified employees, permanent investments, a large commitment to motor sports and innovative products, and has become the largest European motorcycle manufacturer. KTM products are distributed worldwide through more than 35 distribution subsidiaries, three joint venture companies and 2,350 independent dealers.
The challenge and task
For the storage of lithium-ion batteries, a suitable hazardous goods warehouse should be set up. The project had to be developed in the absence of specific legislation for lithium-ion batteries in cooperation with KTM and the battery manufacturer and tailored to this requirement. Sufficiently tempered storage capacity to prevent loss of battery performance during storage was another requirement to consider.
DENIOS developed a solution based on its technical / security rooms. With 7 m2 of floor space and integrated drip pans, the basic requirements for the storage unit were met. Although fire safety was not compulsory, the insulation in building material class A (EI120 insulating panels) was carried out - also against the background of a year-round constant internal temperature of 20 ° C, which has to be maintained at outside temperatures of -15 ° C to 35 ° C.
For this purpose, a combined heating and air conditioning unit is used. Since the creation of combustible gases could be explicitly excluded when charging the batteries or in case of a fault on the part of the battery manufacturer, the internals were not "ex-protected" executed. Door locking system, fire water supply, ramp, equipotential bonding and close-meshed gratings for better handling with hand-held lifting devices are further features.
Result and customer benefits
The customer benefited from DENIOS 'experience in building technology / safety rooms for lithium-ion batteries. In cooperation between KTM, battery manufacturer and DENIOS, a solution has been developed that takes into account the general legal framework as well as the special features of lithium-ion battery storage. An extra safety is achieved by the fire-protected version (F90 / REI90), although this was not mandatory. The temperature-controlled storage prevents a loss of performance of the stored batteries.
Overall, the customer is very satisfied with the planning and implementation, which is also reflected in follow-up orders for DENIOS.
