Traction battery with hurdle-shaped flexible printed circuit

A traction battery comprising:

• a battery array;
• a first circuit board disposed on a first side of the array and having an associated temperature sensor;
• a second circuit board disposed on a second side of the array and having an associated sensing module;
• and
• a flexible printed circuit (FPC) extending from the first side to the second side of the array, the FPC including:
• a flexible substrate that is planar and has opposing first and second planar surfaces and opposing first and second edges extending between the planar surfaces, the substrate having a straight middle portion, a first end portion that is joined to the middle portion by a first elbow portion, and a second end portion that is joined to the middle portion by a second elbow portion, wherein each of the elbow portions are folded relative to the middle portion such that the first planar surfaces of the first and second elbows face each other,
• a circuit supported by the substrate,
• a first connector attached to the circuit and the substrate and connected to the first circuit board, and
• a second connector attached to the circuit and the substrate and connected to the second circuit board such that the FPC electrically connects the temperature sensor to the sensing module.
