Global OEM selects Eaton's power distribution technology for new electric vehicle platform

8 April 2021

Energy management company Eaton today announced that its eMobility business has secured a contract to supply Bussmann ™ series power distribution units (PDUs) and fuses to a global manufacturer of vehicles for use in a new battery-powered light commercial vehicle (BEV), which is a fast-growing segment for BEVs. PDUs are scalable in design so they can be applied to a wide range of future vehicles in the portfolio.

PDUs, also known as junction boxes or fuse boxes, connect the main battery power to the rest of the vehicle, similar to a domestic service panel that connects the main power source to each of the home's derived circuits. When distributing power through the vehicle, PDUs offer a safety function, providing circuit protection.

Eaton's eMobility business won the supply contract due to the unique features it was able to offer over competitors, including the complete integration of the Bussmann series fuses in the PDUs to protect four auxiliary circuits.

"Eaton's extensive experience and application of fuse and circuit protection technology has enabled PDU integration at levels that others could not match," said Eaton's global product strategy, power distribution and protection manager for eMobility business. , Kevin Calzada. "Eaton was able to protect this program through technical agility in the design of PDU resources, ensuring high reliability in the system".

Eaton's eMobility team took advantage of its extensive electrical experience to design a functional, low-cost product to meet the vehicle's stringent circuit protection requirements. PDUs have also undergone rigorous testing to ensure long-term reliability.

“Fuse life simulations are unique in the industry and help OEMs to reduce risk,” commented Calzada. "If not specified correctly, auxiliary fuses may have problems with bothersome trips, but with our experts leading the coordination of fuses, we were able to demonstrate high reliability in the long term with our fuse rating analysis."

The OEM also required that PDUs provide multiple levels of security. Eaton PDUs are uniquely designed with regard to housing access to ensure safe repairs and services. In addition, Eaton units feature a test port that allows an electrical meter to be used as a probe to contact miniature circuit boards that signal if the unit is still charged, preventing the technician from having contact with the discharge voltage.

Eaton's eMobility business was formed by combining the products, experience and global manufacturing capabilities of Eaton's electric and vehicle groups. Eaton plans to develop new products and technologies, including smart diagnostics, smart power electronics and preventive health monitoring systems, to strengthen its global capabilities and provide smart electrification solutions to customers of passenger cars, commercial vehicles and off-road vehicles.
