Embodiment Construction

[0019] see figure 1 , which shows an electronic device 12 (hereinafter referred to as device 12) with a portable power supply. The device 12 comprises a housing 11 having a compartment 14 for housing an energy source (not shown) and a door 16 for closing the compartment. The device 12 also includes an interconnect 20 disposed in the compartment 14 for interfacing a battery power source (such as a primary battery or a secondary battery, such as a rechargeable battery) or to provide a fuel source (hydrogen in some form) The fuel cartridge is connected to a fuel cell (not shown). Although the door is shown pivoting along the side of the compartment perpendicular to the interconnect 20, in some embodiments it may be desirable to access the compartment from the side opposite the interconnect 20 to allow for easier insertion of the battery and fuel cartridge.

[0020] Interconnect 20 distinguishes fuel cartridges from batteries. Interconnect 20 provides a convenient technique fo...

Abstract

A hybrid power supply includes a fuel cell and an interface between the fuel cell and a fuel cartridge or external battery and a switching type DC / DC boost type converter that receives energy from the fuel cell or external battery and is arranged to deliver the energy to a rechargeable cell. The hybrid power supply also includes a fuel cell current sensor / comparator, included in a feedback control loop disposed about the DC / DC converter, which controls in part operation of the converter to provide constant current discharge on the fuel battery side of the hybrid power supply. An adapter that couples a source of AC power such as a charger to the interconnect is also disclosed.

Description

technical field [0001] The present invention relates to the power supply of portable electronic equipment. Background technique [0002] Portable electronic devices are typically powered by primary or rechargeable batteries. The development of the market for portable electronic devices and changes in usage patterns provide opportunities for rechargeable power sources to power electronic devices. Although the energy density of the primary battery is higher, its internal resistance is also higher, and the primary battery is not so suitable for high consumption (>0.2C discharge rate) electronic equipment. Rechargeable batteries can handle large loads, but do not have sufficient energy capacity for many applications. [0003] A fuel cell incorporated in the power supply of a portable device promises a longer run time than conventional battery systems due to its ability to use high energy content fuel. Several fuel cell technologies are currently being developed for commerc...
