At present, the widely used solar batteries in our country mainly include lead-acid maintenance-free batteries and gel batteries. These two batteries do not require maintenance and maintenance and have less pollution to the natural environment, so they are suitable for solar switching power supply systems. So are solar batteries the same as ordinary batteries? ?
The difference between solar battery and ordinary battery is:
1. Different types
The battery uses lead-calcium aluminum alloy as the power grid, so the water solubility and water precipitation are low when the battery is charged, and the shell adopts a sealed structure, and the release of hydrochloric acid is very small. Pile storage time is long. Solar batteries are capacitors used in photovoltaic power generation. At present, there are four kinds of lead-acid batteries, ordinary lead-acid batteries, gel batteries and some alkaline nickel-cadmium batteries.
2. Different features
Solar batteries can be used in different natural environments, such as plateau areas, high temperature, ultra-low temperature and other different standards can be used normally rechargeable batteries. The structure of lead-acid battery consists of positive (negative) plate, baffle plate, lithium battery electrolyte, tank shell, connecting strip and pole pile.
3. Different working principles
The sunlight shines on the solar modules during the day, so that the solar cell modules generate a DC voltage of a certain magnitude, convert the light energy into electrical energy, and then transmit it to the intelligent controller. After the overcharge protection of the intelligent controller, the electrical energy from the solar modules delivered to the battery for storage.
A normal battery is the entire process of delivering current to a circuit outside the circuit. Charge and discharge methods can be divided into constant flow and constant resistance charge and discharge, which can be divided into continuous charge and discharge and interrupted charge and discharge. Continuous charging and discharging is the charging and discharging method in which the working voltage is stopped under the charging and discharging standard, and interrupted charging and discharging is the charging and discharging method according to the specified charging and discharging standard.
What is a maintenance-free battery? How many years can a maintenance-free battery last?
Maintenance-free batteries are now widely used in cars. In fact, it is also a lead-acid battery, with excellent performance of high performance, long life, pollution-free, maintenance-free, safe and reliable. So what is a maintenance-free battery? How many years can a maintenance-free battery last?
