Problems solved by technology

According to the current power supply technology, it is still unable to meet the demand for long-term continuous power consumption despite the small power requirement. The fundamental reason is that the service life of the power supply for continuous and stable operation is too short. 1,000-2,000 hours; the service life of the direct alcohol fuel cell power generation system that has recently become a hot spot for development is only 500-1,000 hours, etc.

Abstract

The invention discloses a combined power supply. The combined power supply mainly comprises a generating device, an accumulation device capable of recharging and releasing electricity repeatedly, a controller and a charge manager. The combined power supply is characterized in that the ratio of the rated power of the generating device to the rated consumed power of the whole power requiring systemneeds to be selected as large as possible; and the ratio of the single charging time of the accumulation device charged by the generating device to the single working discharging time of the accumulation device alone needs to be selected as small as possible. Regarding situations that the generating device has relatively short service life and relatively small power consumption of the power requiring system, the combined power supply in the field of effectively prolonging the actual working time of the power requiring system is particularly significant.

Description

technical field [0001] The invention relates to a combined power supply device. Background technique [0002] In the vast territory of our country, the area covered by mains power is very limited. Most of the "no electricity" areas have to give up many technical applications due to the inability to use mains power, and most of these technical application fields involve national strategic interests. For example, the network layout of disaster prevention and early warning systems, dynamic monitoring of long-distance high-voltage transmission lines, long-distance communication relay stations, seamless monitoring of thousands of miles of border defense (that is, digital defense duty), etc., the technical bottleneck is unattended power supply. According to the current power supply technology, it is still unable to meet the demand for long-term continuous power consumption despite the small power requirement. The fundamental reason is that the service life of the power supply for ...
