Solar cells are the converters that convert mild power into electrical energy, and don’t store electrical energy, so the lifePo4 battery is crucial when there isn’t a light or power to the load This chapter describes the lifePo4 batteries which can be commonly utilized in solar power generation methods.
The battery utilized in solar energy generation system, commonly recognized because the secondary battery, the usage of rechargeable batteries, photovoltaic power technology system in the battery, LiFePO4 battery pack as a floating cost of the work, no charge should be very little discharge.In general, The battery for digital merchandise is a silver oxide battery or a gradual discharge sort nickel-cadmium battery, and a low-discharge sort lead-acid battery is used for the electric power. For such a secondary battery, the next properties are generally required:
Using photo voltaic cells within the setting have lengthy-term stability of the charge and discharge characteristics,For the reason that variation vary of the light incident on the photo voltaic cell is large, the charging efficiency is high in a wide range of the charging present.
– Overcharge resistance, over discharge.

– Long cycle life.
– No leakage, no fuel emission, or much less leakage, much less gasoline emission.
– High energy density.
– low cost
The so-known as floating charging system, refers to the ability supply (equivalent to photo voltaic cells> related with the battery properly, when the facility enter energy, along with providing load turtle energy, but in addition a small present on the battery charge, and when the ability isn’t any energy enter, the battery Discharge to the load power supply.
Nickel-cadmium battery anode lively materials is nickel oxide, cathode energetic substances is cadmium, lithium battery pack lithium ion battery battery pack and electrolyte with potassium hydroxide, lifePO4 battery pack such open kind and closed kind two, in recent years, largely in closed type.
Ni-Cd batteries have the following benefits:
– Resistance to overcharge, over discharge ability, usually do not set up a stable charging circuit may also be used
– Long life, cost and discharge cycles of several hundred instances or more, the shallow depth of discharge gentle load, the charge and discharge cycle of up to one thousand times,
– The interior resistance is small, there may be excessive-speed discharge, and the discharge voltage fluctuations
– Will be utilized in a large temperature vary,
– And the size of the identical battery, the operating voltage can also be close, so there may be interchangeability.
The battery has the next disadvantages:
– Self-discharge bigger
– Capacity quantity is relatively small
solar powered portable generator, charging is carried out at a price of less than 1/10 of the battery capacity C, that is, lower than 0.10C, in a particular case, rechargeable battery news and the newly charged quick-cost type could be charged with a present of lower than 0.33C. Usually the foundation of the cost current to contemplate the output of photo voltaic cells to 0.10C of present to charge, to succeed in full cost to be greater than 10h.Therefore, is the largest day of the sunshine time could be very brief, only 3-4h, Therefore, the area of solar cells with electronic merchandise should be large, generally the maximum sunshine when the charge present to about 0.3C to use, however the precedence in battery life, the current limiting resistor can be connected in series to the charging circuit , So that the enter current is lower than 0.1C.
