• Sourcebook Electromobility

    Baden-Württemberg and the Stuttgart Region play a leading role in the field of electromobility in Germany and Europe. The Sourcebook Elektromobility gives a detail-rich overview of the various activities in this area in southwest-Germany and allows for search functions by full-text, organization type or category.


TheSys GmbH is an independent engineering services provider that designs cooling systems, air conditioning systems and heat exchangers. TheSys covers the entire field of thermal management in vehicle, railway, marine and industrial applications.TheSys assists and advises customers in the design and assessment of cooling systems and related operational strategies on site. This includes the design and layout of cooling and air conditioning system components, the design of new heat exchangers in line with customer requirements, the supply of battery coolers in small series and measurements with heat exchangers and cooling systems. We also conduct vehicle testing and failure analyses for radiators, including tests regarding the ageing of coolants. We support e-mobility by supplying battery coolers and designing battery cooling systems, especially low-temperature cycles, chillers and cold/heat stores. Our battery coolers feature extremely good surface temperature homogeneity of less than 1 Kelvin. This homogeneity of temperature distribution in the cell contact area does not involve any loss of heating capacity or pressure loss. In addition, our battery coolers are extremely slim and light. With our thermodynamic simulation method, we analyse hybrid and electric vehicles under transient driving conditions. This identifies the temperatures within a battery at any given point of time.
