MTA, a multinational company operating in the global automotive sector through 3 Business Units – Electric, Electronic, and Power Electronic – showcases during IZB (Hall 2 Stand 2409) a new junction box developed for ӫ-Berlingo and e-Partner, the new generation of multipurpose commercial vehicles produced by Stellaris. Both developed on the group's EK9 electric platform, the two vans by CITROËN and PEUGEOT feature a more economical driving style: gentle acceleration and regenerative braking allowing you to maximize the range.


The junction box developed for the two vans ӫ-Berlingo and e-Partner is a 450 V unit installed in the battery pack compartment, which on the one hand supplies current to the electric motor and, on the other, recovers energy during braking to recharge the battery. The unit contains an HV fuse and a PCB (Printed Circuit Board) that allows the current, voltage, and battery charge to be measured.


The busbar developed for the junction box of ӫ-Berlingo and e-Partner is blanked in the MTA site in Codogno, the PCB is assembled in Rolo, the site specialized in electronics, and the plastic is molded by MTA Morocco where the final assembly is also carried out and the product forwarded to the Stellantis facility in Spain.


MTA currently offers a comprehensive electrification range including Junction Boxes and high-voltage power distribution boxes (PDUs), already installed on electric and hybrid cars from several major manufacturers.


For the development of electrified architectures, significant investments have been made by MTA in R&D and production techniques. The use of specific materials also required the complex search for new suppliers, resulting in further evaluation and qualification processes. MTA has been able to create a short supply chain, mainly EMEA, achieving two main advantages: reduced design development times with experts in new manufacturing technologies and less CO2 emissions.
