Electronic control of the charging process

PulseTronic, which is made in Telwin, is our answer for charging/maintaining traction batteries used in Automotive applications, no matter whether for motorcycles, cars, lorries, heavy machines, etc.

This sophisticated technology, which can be used to charge all types of 6/12/24V battery, and more specifically WET, GEL, AGM, MF, SPIRAL, START/STOP batteries, is a reference for all of Telwin’s professional products.

Its capacity to diagnose battery conditions moment by moment, together with specific interventions aimed at restoring optimal operativity, are the two essential elements on which Pulse Tronic technology is based.

Constant control of the charging process on the one hand prevents possible battery overcharging and overheating, and on the other hand returns the battery to optimal condition; the result is a perfectly charged battery with a longer life.

When batteries are not used for long periods they tend to discharge naturally, so charge maintenance is just as important as the charging process.

PulseTronic technology uses intelligent monitoring and special wave forms (impulses) to maintain the optimal charge without generating overheating or making modifications that damage the chemical structure of the battery, even over extended periods (e.g. vehicle maintenance during periods of non-use).PulseTronic technology also pays special attention to safety by creating and defining the correct conditions to fully protect the on-board electronics of the vehicle while charging/maintaining the battery and without being disconnected from the vehicle.

The multiple advantages of this technology are evident even when charging several batteries together in serial or parallel.

From a practical viewpoint, battery maintenance, namely charging and optimal charge maintenance, occurs over 8 separate phases, specific for every constructive type of battery, with each phase being characterised by a special functionality and wave form.


Control of battery conditions and check of correct voltage set on display.


Detection and recovery of sulphated or low batteries; pulses allow the removal of sulphate from the lead plates at its early stage. The battery’s positive response to the pulses allows to continue with the charging process.


Analysis of the battery status. The  charging current is lower than the one set.


Recharge with the set current or with the maximum current up to 80% of the battery capacity.


Recharge with decreasing current up to 100% of the battery capacity.


Check run if the battery holds the charge.


Maintenance of the charge at constant voltage.


Recovery of optimal charge by pulses avoiding the natural self-discharging 

PULSE-TRONIC technology therefore offers the following advantages:

  • it can be applied to all types of battery;
  • it gives complete control over the charge current;
  • it protects the electronic components on-board vehicles without having to disconnect the battery from the vehicle during charging;
  • it guarantees less battery overheating during the charge phase;
  • it guarantees longer useful life to batteries.
