Cable-Resistance Compensation USB Configuration Files for IC Series Battery Charger

Product Series: IC

Article No: FAQ065

In order for the Delta-Q charger to deliver accurate charge voltage, Delta-Q IC series chargers have built-in software settings which compensate for DC cable resistance. The default cable-resistance compensation for IC Series charger is 20mOhm. 

For a setup with a shorter/longer DC cable, the user may wish to further decrease/increase the cable-resistance compensation to optimize charging.

 

The cable-resistance compensation is calculated base on combined resistance of both the positive and negative conductors(round trip). 

As an example: for 20mOhm cable resistance compensation.

  • The conductor from battery charger positive terminal to battery positive terminal is expected to have 10mOhms of resistance. 
  • The conductor from battery charger negative terminal to battery negative terminal is expected to have 10mOhms of resistance.
