This charger is a more complex one than the others available over the internet, and among its features are:
- All the parameters for charge and discharge can be entered directly in the charger.
- The PC is useful only for PIC firmware patch and for output graphic plotting.
- A second P-channel mosfet is added for up to 10A charge current or for no self-powering diode.
- Integrates a 16×2 lines LCD display
- Integrates up to 7 different charge/discharge profiles
- The batteries can be charged,discharged or cycled (charge after discharge)
- Parameters for each battery profile:
- Number of cells (from 1 o 7)
- Cell capacity (useful for automatic timeout calculation)
- Cut-off voltage per cell
- Delta peak per cell
- Charge current (up to 10A or 5A plus the diode)
- Discharge current (up to 30A)
- Peak control inhibition
- Timeout in function of the cell capacity.
- Support for costant voltage supply (motor test) with adjustable output
- Fast current control (200Hz) and low noise values (1mV resolution for batteries)
- Display during charge of current,voltage,peak voltage,delta peak, capacity, time
- Display during discharge of current,voltage,peak voltage,cut-off, capacity, time
- Acoustic buzzer for end of operation signaling
- Automatic recovery in case of power supply failure
