Work PWM charge controller for wind turbine is based on the so-called PWM (Pulse Width Modulation) technology.
At the final stage of the charge, these controllers use pulse width modulation charging current. You can still charge the battery to 100%.
The process of charging the battery, controlled by PWM controller , consists of 4 stages:
The charge current adjustable
At this stage, the battery gets or all of the current, which is able to issue a wind generator, or the charging current is determined manually. At the same time gradually increasing the voltage at AB
AB voltage reaches a certain level, and then the controller begins to maintain a constant voltage, by reducing the charging current through PWM. This makes it possible to prevent overheating and gas formation in the battery, as well as produce a full charge. As the battery charge, the current gradually decreases.
The batteries with liquid electrolyte to improve their work with periodic charge to the gassing, thus there is a purification plates and electrolyte mixing.
AB is fully charged and the battery voltage is reduced to prevent further heating or gassing of the battery. AB maintained in a charged state (stand by).
In an improved model of PWM kontrorllerov for wind generator have the option of charging is not necessarily a standard maximum current, and a manual setting of this parameter. Charging current should be 1/10 of the battery capacity.
PWM kontrorller for wind generator dynamically check the current and voltage of the battery charge. When the battery is low, its resistance is small, so when charging through it can go high current (more than 1/10 of the tank). Therefore, in an initial charging cycle controller ensures that the current does not exceed 1/10 of the battery capacity. As the charging resistance of the battery increases, the current decreases and the voltage begins to rise on the battery.
Adjust the current would be incomplete if the controller should regulate only the battery charging current. In advanced models PWM kontrorllerov charge for wind generator implemented control the discharge current.
Example. Battery charging Battery 60 A, the charging current, respectively, exhibited 6 A (1/10 capacitance). Here, all is well. But if this user needs to connect the inverter to the battery, and it will begin to drain the battery current 13 A? It turns out that the battery, instead of charging, discharging current is 7 A. But then the wind turbine controller sees that the load consumes as described in Example 13 A, and increases the current from the wind turbine up to 19 A, and it turns out that 6 A go to the battery and 13 A - the inverter.
Default PWM сontroller for wind generator are set to automatic detection mode (mainly 12/24/36 or 48). But at the same time, the menu controller windmill provides manual installation charge voltage. This is necessary in case the battery manufacturer indicates that for maximum efficiency they need to charge a kind of non-standard voltage, for example, 14.6 V. Then, putting manually charging voltage, the user will achieve maximum efficiency battery charging, which will undoubtedly prolong their service.
PWM kontrorller charge for wind generator can perform three functions:
charge the battery from the wind turbine;
load distribution between energy sources.
It has high reliability and excellent for a wide temperature range from -40 to +40 C.
An important function of some of these models in addition to the charge controller of the wind turbine, is to control the disposal of surplus energy (heating elements). In advanced models PWM сontroller for wind generator in which case an intelligent system connection heaters (ie, PETN can be connected to the wind generators are not 100% of its capacity, and, for example, up to 50%, depending on what kind of wind turbine generates power, and how much to consume batteries).
