EV charging and power electronics
Thin gauge, tight tolerance, high mix, and insulation that will not forgive a sharp edge.
EV charging and power electronics work is thin-gauge, tight-tolerance and high-mix, with short product cycles. Two factors dominate. The first is changeover time, because volumes ramp and mix changes faster than in traditional switchgear. The second is edge quality, because these assemblies are usually insulated by film, overmoulding or encapsulation, and none of those will conform to a sharp corner: a burr or an unradiused edge becomes an air void at the point of highest field stress. Chamfering and deburring are part of the electrical specification here rather than finishing operations.

Technical background
Bending
Springback compensation in busbar bending
How to predict and cancel springback in copper busbar bending: the governing ratios, a worked calculation, overbend by EN 13601 temper, and CNC offset tables.
Standards
Which busbar standard applies to your job
A decision tree from product type, voltage class and destination market to the governing standard set, with each standard placed at its actual scope boundary.
Materials and finishing
Copper temper and minimum bend radius
How EN 13601 tempers R220, R240 and R290 set the minimum bend radius of copper busbar, how to read a mill certificate, and when annealing is the wrong answer.
