Efficiency is still lower.
Following power feeding system is designed in typical battery check device: will be equivalent to the lifting of the end of the dendrogram
Connection wiring between pressure converter and inspection portion is set as the connection wiring between power supply device and inspection desk.Corresponding to for one
And it checks multiple inspection portions of multiple batteries and multiple type of voltage step-up/down converter is set.Therefore, it is necessary to huge wirings.To contract as far as possible
The setting layout of short huge wiring, battery check device is also possible to be restricted.Also, because turning in order to which multiple bucks are arranged
Parallel operation or connecting terminal, so causing power supply device enlarged.
Japanese Unexamined Patent Publication 2003-084050 stores the consumption electric current (consumption current value) of multiple circuits in memory, and
According to each circuitry operating conditions, the battery terminal voltage value in two different states of consumption electric current is detected.From memory
Read the consumption electric current of each circuit to work in these states.It is obtained by using the consumption electric current read is added (combination)
The value obtained predicts the battery terminal voltage value in the state of predetermined consumption electric current, to detect remaining battery power.
As the solution to the problem, photovoltaic cell is relatively suitable.Compared with traditional electricity generation system, photovoltaic cell
Generating efficiency is high, and clean energy, waste is free of contamination.In addition, the energy as provided by every cube volume and weight
Amount be almost several times to tens times of conventional batteries, thus it may be said that photovoltaic cell as the power supply of miniaturized electronics is to have
