Abstract
An electricity generating backpack includes a generator that generates DC electricity for application to a load. The backpack includes an electronic control module (ECM) adapted to adjust an emulation resistance for the generator to maximize power output in response to a weight of the payload in the bag and an up and down movement of the bag in response to the walking or running cadence of the wearer of the backpack. The load may include a battery that stores DC electricity and a warming element in a warming pouch adapted to hold the battery. The warming element receiving DC electricity that is used to generate heat to warm the battery to maintain the battery within a desired temperature range for charging/discharging. When no load is connected, the DC electricity may be diverted to a power resistor to absorb power and to dissipate the power as heat.
