Control & interface

TECSUP has deep knowledge relative to the control (charge, temp...) and interfacing of its products and systems:

- Parameters & configuration (charge curves)
- Bench testing
- Control software
- Charge Indicators
- "Multi-plexage"
- Man-Machine Interface
- USB output
- PC monitoring
- Qualification & electrical control of equipment (motors, printers, lights)

TECSUP puts out different interface possibilities such as the hub CAN, RS232, and SMBus, allowing to command at a distance and to be readily available for the user or the technical maintenance team, all the necessary information (current, voltage, power of charge, battery and charger temperature, rate of charge, energy available). These interfaces can supply a diagnostic on the state of the battery and its charger, guaranteeing an optimized replenishing of the batteries.

For the recharging of small equipments (smartphones...) and a direct consultation of the data (gauge battery ...), TECSUP can equip your energy system with USB ports.

Charge Curves

For every battery technology (lead open, lead sealed/Gel, lead calcium standard, deep discharge lead calcium, Lithium), an adapted charge curve exists. The TECSUP high frequency chargers are capable of recharging many different battery technologies thanks to many adapted charge curves, recommended by the battery manufacturers.


3 stage Charge Curve


In order to restitute the initial battery capacity while preserving them, TECSUP applies adapted charge curves indicated by the battery manufacturers.

  • BOOST / rapid charge: restitution of 80% of the batteries charge in a very short time.
  • ABSORBTION / equalization: Charge top-up to 100% of the battery capacity.
  • Floating / maintenance charge: compensation between the permanent consumption and the auto-discharge of the battery while maintaining an optimal charge. The charger can remain connected permanently.

These three sequences link automatically.

5 stage Charge Curve


A five stage charge curve is more adapted to Industrial applications, Cycling. It allows for an optimal charge of batteries that are in series. However, it is strongly advised not to use power during the charging, in order not to damage the consuming equipment with power surges that occur during the equalization phase.

The 5 stage charge curve allows for:

  • De-sulfating the battery elements and to create flow around the electrolytes, thanks to the ‘equalization phase'. This is in order to regenerate a damaged battery, or one that has decreasing capacity.
  • Obtaining a uniform recharge of a battery park that are cabled in Series.

The BOOST, ABSORBTION and FLOATING phases are similar to those of the 3 stage charge curves.
