Power Management Assembly: Engineered power distribution for next-generation integrated electrical architectures
TE’s Power Management Assembly (PMA) solution delivers a fully engineered, busbar-based power path that supports copper-to-aluminum transitions while helping to reduce integration complexity and accelerate production readiness.
Integrated busbar + connector power distribution. As electrical architectures move to higher voltages and aggressive cost targets, automakers are accelerating the transition from copper to aluminum conductors to reduce weight and improve system efficiency. At the same time, tighter packaging and integrated busbar-driven systems are making traditional component-based approaches more complex, harder to scale, and more difficult to validate globally.
At TE Connectivity, we work with automakers and system suppliers to design and deliver next-generation power distribution solutions tailored to these challenges. Our Power Management Assembly solution delivers a fully engineered busbar-based power path that supports copper-to-aluminum transitions while helping to reduce integration complexity and accelerate production readiness.

Frequently Asked Questions
What is a Power Management Assembly?
A PMA is a fully engineered power distribution solution that connects electrical interfaces with integrated conductors, connection systems, and joining technologies. PMA delivers a complete, bespoke, connection-to-connection power path designed for high-current, high- and low-voltage vehicle architectures.
How is PMA different from a traditional busbar or cable assembly?
Traditional busbar and cable assemblies are often focused primarily on conductor geometry, material, and flexibility. PMA is a custom solution that combines conductors, connectivity, joining technologies, thermal management, and validation expertise into a single, engineered solution, helping reduce integration complexity and program risk.
What applications can PMA support?
PMA can be used across battery systems, charging paths, traction paths, power distribution units (PDUs), battery disconnect units (BDUs), inverter systems, and other high-current power distribution applications across high- and low-voltage architectures.
Does PMA support copper-to-aluminum transitions?
Yes. PMA is engineered to support copper, aluminum, and hybrid conductors, helping automakers and their system suppliers reduce weight and optimize costs while maintaining a high degree of electrical and mechanical performance.
How does PMA reduce integration complexity?
PMA consolidates conductors, interfaces, joining technologies, and engineering support into a single solution, reducing the need to coordinate multiple suppliers and simplifying validation and sourcing processes.
Is PMA designed for automated manufacturing?
Yes. PMA solutions are designed to support automation-ready manufacturing processes and scalable production environments, helping to improve assembly consistency and production efficiency.
Why choose TE Connectivity for automotive and commercial vehicle power distribution solutions?
TE combines decades of high-voltage connectivity expertise, advanced material and joining capabilities, validation infrastructure, and global manufacturing support to help automakers and system suppliers reduce risk and accelerate deployment of next-generation power.
