Thermoelectric battery and accumulator co-used power supply system

Abstract

The invention discloses a power supplying system of temperature differential battery and accumulator in the DC power supplying domain, which comprises the following parts: accumulator, switch, controllable silicon, heat accumulating groove, load, heat exchanger, connecting pipe and pump, wherein the temperature difference battery is generating part and control part; the accumulator is accumulating part; the temperature differential battery is attached on the solar plane of heat exchanger; the connecting pipe connects heat-exchanger, pump and heat accumulating groove together with water in the pipe; the thermal insulating material is covered on the back and lateral of heat-exchanger, outer surface of connecting pipe and heat accumulating groove; the anode of two accumulators cascades a controllable silicon, which parallels temperature differential battery at A and B point; two control poles of controllable silicon connects A and B point separately, which supply power for load R in connection with switch K. The invention improves energy transmission rate without energy consumption and pollution, which lengthens accumulator utility lifetime.

Description

technical field [0001] The invention relates to the field of direct current power supply, in particular to a power supply system which uses thermoelectric batteries and accumulators in combination to provide electric energy converted from solar energy to electric equipment in a sufficiently reasonable and stable manner. Background technique [0002] At present, the commonly used batteries at home and abroad can be divided into two categories: one is the storage battery, and the other is the primary battery, both of which have their own advantages and disadvantages. A primary battery can convert chemical energy into electrical energy. When the substances participating in the reaction are consumed to a certain extent, its life is over, and the chemical energy stored in the battery can no longer be recovered, so it is also called a primary battery. In addition, because waste batteries contain mercury, After harmful substances such as cadmium and lead can cause serious environme...

Problems solved by technology

However, the power supply system with only batteries cannot supply power for a long time due to the limited battery capacity, and the charging time is long. It takes 4-5 or even more than ten hours to charge once, which is inconvenient to use, and the charging times of the batteries are limited. expired

[0004] In addition, the "power supply system using both solar cells and storage batteries" disclosed in Chinese patent CN200410054730.6 combines solar cells and storage batteries to provide power. It uses solar power generation technology, and its power generation efficiency is limited and can only be generated during the day.

Since there is no anti-backflow measure, it may even lead to backflow
