Introduction to the BAC25A battery charger

As we know, batteries are the fundamental element in the event of an electrical break, since the installation must continue to work. In order for the batteries to be in perfect condition, it is necessary to charge them to compensate for their loss of energy and keep their voltage within the predefined limits.

The Amperis charger is designed to charge the battery much faster and to recharge the battery quickly after the discharge test. It is a portable charger that is used to charge mainly Ni-Cd and lead-acid batteries, with 2 charging modes that offers the possibility of maintaining and charging the batteries with a constant current or with constant voltage.

The equipment generates current up to 25A, in terms of the range of output voltages, this charger covers from 10 to 300 V DC. From the screen located on the control panel, the operator knows the information of the charging process, being able to modify the load current, time and other parameters to customize the operation. It also has protection of overvoltage or low voltage, overcurrent and thermal protection

In the image above we see the BAC25A instrument connected to a test battery through the power cables, being able to optionally use the voltage detection cables. Once the charging process has started, the BAC25A device maintains the constant I or V level depending on the selected charging mode, ie charging with constant current with the IU charging mode. In this mode the voltage increases to a level close to Vfinal (boost voltage) and the device changes to a constant voltage mode (float voltage), this is when the current starts to decrease. The process ends when a predetermined minimum intensity value is reached, which indicates that the load has been completed and has been completed.

However, when charging the battery according to the UU charging mode, the process develops at constant voltage. In the event that the defined current limit is exceeded, the charger changes to a constant current mode, continuing the charge in this mode (the charging process proceeds at a constant current equal to the specified limit). Thus, the charger continues to charge and the current decreases with time until it reaches the predetermined minimum, at which point the charger will change to a floating charging stage and the V will decrease at a predetermined float voltage.

The time is decreased to its minimum value, at which point the charger will change to a floating charge stage and decrease to a selected float voltage.
