Weiss has been intensively involved in battery testing for over 15 years. In the process, a comprehensive safety concept has been developed. With this modular system, all risks are recorded and minimized.
Weiss not only manufactures climate chambers for testing batteries, but also develops entire testing systems, including a climate chamber, charging and discharging stations, media conditioning and a high-pressure water mist system.
Battery driven vehicles will be followed by hydrogen stacks. In fuel cell driven cars batteries and hydrogen stacks will be integrated. Both techniques have specific risks. A testing system for batteries cannot simply be supplemented or converted to a hydrogen application. An ATEX consideration also does not always lead to the desired result. Further, additional modifications are necessary. High demands are placed on materials, measuring probes, reaction times, reporting chains and the process sequences. In addition, there always remains a residual risk to be precisely defined for the user and operator of the test facilities, which must be countered with administrative measures.
Together with the TÜV, Weiss has developed a system where, in several steps with the user, the risks of the various test facilities are assessed. Once the risks have been defined, a safety concept is built on them. A modular system is now available for many test set-ups and hydrogen applications, which allows safe operation under defined conditions.
Weiss would like to present this tool and the associated procedure to the expert audience. The analogy between the hazard levels 1 to 7 (for batteries) and the hydrogen (H2) levels 1 to 5 defined by Weiss will be highlighted.
