Electric Mobility

In addition to assembly lines for electric drives, which include stator as well as rotor and gear case assembly, Hirata has extensive references and process know-how in battery assembly. This know-how is complemented by a high level of competence in the production of IGBTs for power electronics of vehicles with electric drives. Hirata can also draw on experience in the assembly process for fuel cells.


Hirata has developed and implemented completely automated systems for the assembly of electric drives for automotive applications worldwide. Thereby, plants for rotor and stator assembly using conventional windings and the "Hairpin-Technology" as well as assembly lines for the final assembly of complete electric drives, consisting of motor and gear unit, were realized.



Together with partners from industry Hirata began very early to develop innovative processes for the assembly from battery cells to battery blocks and for the final assembly of complete vehicle batteries. These processes have been designed and implemented in the form of serial production plants at the leading manufacturers of electric vehicles in Asia as well as in the USA and Europe. 


IGBTs have become the most widely used power semiconductor in industrial applications and are also used in the power electronics of electric vehicles nowadays. In the assembly of IGBTs, they are potting after fitting. In this case, innovative processes with ultrasonic and vacuum technology are used, wherefore Hirata has developed its own equipment, which is used several times. 


Power modules

Every electric vehicle needs a power module to control the electric engine. In cooperation with customers in the automotive industry, Hirata already began with the development of the first power modules and corresponding technologies many years ago. Today Hirata is one of the leading manufacturers for completely automated assembly systems for these modules.

Fuel cell

Dispite special requirements in the production of fuel cells, starting with the lamination of the anodes and cathodes, over the production of the actual cells using bipolar plates, up to the final assembly of the complete fuel cell unit, Hirata has supplied test systems in the international market and now also series production systems to well-known manufacturers.
