Panasonic makes the cells for the Powerwall, while Tesla builds the battery module and pack.
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages. Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer. The Tesla coil (L1, L2) , an air-core double-tuned resonant transformer, which generates the high output voltage. 2  Optionally, a capacitive electrode (top load) (E) in the form of a smooth metal sphere or torus attached to the secondary terminal of the coil.
