What's the difference between solar cells and ordinary cells?
Lead-calcium alloy is used as the grid frame of vehicle battery, and the amount of water decomposition and evaporation generated during charging are low. In addition, the shell adopts a sealed structure, and little sulfuric acid gas is released. Therefore, compared with the traditional battery, it has the advantages of no need to add any liquid and long storage time of the wiring pile.
Solar storage battery is the application of "storage battery" in solar photovoltaic power generation. At present, there are four kinds of lead-acid maintenance-free batteries, ordinary lead-acid batteries, colloidal batteries and alkaline nickel-cadmium batteries.
2. Different characteristics
Solar cells are suitable for different environmental requirements, such as batteries that can be used normally at high altitude, high temperature and low temperature.
The structure of automobile lead-acid battery is mainly composed of positive (negative) plate, separator, electrolyte, tank shell, connecting strip and pole post.
3, the working principle is different
During the day, the sun shines on the solar cell module, which makes the solar cell module generate a certain DC voltage, converts light energy into electric energy, and then transmits it to the intelligent controller. After the overcharge protection of the intelligent controller, the electric energy from the solar cell module is transmitted to the storage battery for storage.
The process of automobile battery transmitting current to external circuit. Discharge methods can be divided into constant current discharge and constant resistance discharge, and can also be divided into continuous discharge and intermittent discharge. Continuous discharge is a kind of discharge mode that discharges continuously to the termination voltage under specified discharge conditions. Intermittent discharge is a kind of discharge mode in which the battery is intermittently discharged to a specified termination voltage under specified discharge conditions.
