Aluminium Busbar, Flexible Shunts for EV Applications

Aluminium flexible busbars are welded at both ends, with a flexible middle section that reduces mechanical stress on the busbar connector, enhancing installation flexibility. Aluminium busbars provide the necessary conductivity and thermal properties while offering lighter weight and significant cost advantages. These characteristics make them ideal for applications such as EV battery packs, where weight and cost are critical factors.
