What is Pulse Width Modulation (PWM) charging?
How does a Pulse Width Modulation Charge Controller Work?
The PWM charger constantly monitors the battery pack's state of charge to determine how much current to put back in.
The advanced type of Charge control ensures efficient charging of the batteries. PWMs help to regulate the often inconsistent voltage put out by power sources in order to protect the system batteries from overcharging. The PWM charger constantly checks the current battery state and self-adjusts accordingly to battery condition to send only the right amount of charge to the battery, eliminating over or under charging.
In essence, this type of charge controller works by reducing the current from the power source according to the battery’s condition and recharging requirements, which is in contrast to on/off charge controllers which suddenly cut off power transfer to minimize battery overcharging. The PWM charge controller does this by checking the state of the battery to determine both how long (wide) the charge pulses should be as well as how fast they should come.
By constantly analyzing the battery information, the PWM charge controller self-adjusts and sends the appropriate pulse to charge the battery. The PWM charger varies the length and speed of the pulses sent to the battery as needed. This is essentially a rapid on and off switch. When the battery is nearly discharged, the pulses may be long and continuous, and as it becomes charged, the pulses become shorter or trickled off.
Units with the float charging mode maintain batteries in storage that self discharge or batteries that can go weeks without use. This mode is not needed for often used carts with regular charging intervals.
This type of charge controller is idea for golf carts where deep discharge is a regular occurrence.
It provides several key benefits:
higher charging efficiency,
Optional float charging,
and healthier batteries that operate at full capacity.
