Battery welding with lasers is much faster than with conventional welding tools such as resistance spot-welding or ultrasonic welding. The process is contactless and, unlike resistance spot-welding, requires access to only one side of the part, enabling greater flexibility, lower cost and simpler and faster methods of clamping down parts.
The coil becomes a transformer, stepping the voltage up. If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts! The high voltage is carried away from the coil by a high-tension cable that looks like a short piece of spark plug cable and runs to the distributor tower.
