Future Market Insights
Charge controllers are used in different type of power generating systems regardless the source i.e. wind energy, solar energy, hydro power based, fuel systems based, etc. and are essential for all power system applications. The growing demand for power systems across the globe is expected to boost the charge controller systems market. Charge controllers regulate the batteries to limit the voltage/ current from overcharging and discharging, thus protecting them and increasing their overall service life. Preventing the batteries from damage during the charging process also optimize the overall system performance.
Charge controller systems, specifically, are used during solar power generation in Photo Voltaic (PV) systems. They are connected in between the PV array cells and the battery to regulate the current/ voltage flow. In case of overcharging, when the battery charges power more than the rated voltage/current, charge controllers disconnect the battery from PV arrays in the absence of load. To control the input voltage, charge controllers block the reverse current. Reverse current flows in the consequences of overcharging. By using the diode in series and shunt, it can be controlled and if the charge exceeds more than the rated voltage, the battery will be disconnected from the PV system. When used in wind power generation system, charge controllers dissipate the excess power in the form of heat in case of the battery is overcharged.
Solar charge controllers are basically of two types – pulse width modulation (PWM) and maximum power point tracking (MPPT). MPPT charge controllers are widely used in solar power generation for their high efficiency and reliability. They allow solar panels (PV arrays) to operate at the optimum output voltage to boost the performance more than 30%. PWM charge controllers are available in the market for a long time and they are less efficient and cost low when compared to the MPPT.
Various basic switching controllers include – temperature compensation, equalization charging, meters and indicators for system status and operating information. In order to regulate the battery by set point for load disconnection during discharging and overcharging of the battery, the following steps are followed
Regulate set point: Fix the set point at maximum permissible voltage to allow the battery to charge. If the voltage increases more than the set point, the controller discontinues the charging. The specific selection of the set point depends on the operating temperature and battery chemistry.
Voltage Regulate hysteresis: Voltage regulate hysteresis is an important factor causing charging effectiveness of a controller.
(LVD)Low voltage disconnect: Low voltage disconnect is a set point at which the load is disconnected from the battery to stop over discharge
(LVDH) Low voltage disconnect hysteresis (LVDH): It is the voltage at which reconnected
