The 14V power module is an electronic device that takes the place of the generator on a traditional vehicle. On a hybrid or electric vehicle the 14V power module converts high voltage (400 V) direct current (DC) to low voltage (12V-15.5V) DC for accessory electrical operation, and to charge the 12V battery.
The 14V power module is capable of supplying up to 274 Amps of 12V DC current.
