Solar street light price for the family

Here are several kinds of conventional controller for battery charging methods: compared with the constant current charging method, the charging process is more close to the optimum charging standards, very little this charging method electrolysis of water, avoid the battery overcharge, but at the beginning of the charging current is too large, the battery life will

solar controller is divided into control and electric, half power controller used for solar street lamps and other lighting system and solar power system, the control of battery charging and discharging too lead to real life problems. Here are several kinds of conventional controller for battery charging methods:

1, the constant current charging method

constant current charging method is used to adjust the charging device output voltage or change with the resistance of the battery in series, the intensity of charging current unchanged of charging method, the control method is very simple, but due to the capacity of storage battery can accept current is as for the recharge gradually declined, and so late to charging, charging current used for electrolysis of water to produce more gas, can make the gas too much;

2, constant voltage charging method

home use solar street light price constant voltage charging charging power supply voltage in the process of constant value in all the charging time, gradually rise, as the real time voltage of the battery current gradually decreases. Compared with constant current charging method, the charging process is more close to the optimum charging standards, very little this charging method electrolysis of water, avoid the battery overcharge, but at the beginning of the charging current is too large, will have a big impact to battery life, and easily make the battery plate bending, so cause scrap;

3, phase mise-a-la-masse

( 1) Phase method: home use solar street light prices first to constant current charging to predetermined voltage value, and then to complete the rest of the constant voltage charging;

　　( 2) Three-stage charging method: at the end of the charging and using constant current charging, with constant voltage charging in the middle. When the current attenuation to the preset value, by the second phase transformation to the third stage. This method can minimize the volume, but as a kind of fast charging method is used, is still a certain limit.

this is shandong home use solar street light price solar street lamps factory staff summary of several kinds of conventional controllers to the battery charging method, selecting a correct way can guarantee the service life of the battery charging, thus ensuring the normal lighting, solar street lamps later we will introduce several to battery fast charge method, if you have any other questions can be consulting us.
