Hello All,
I have 2 converters connected (in parallel) to my BMS and so to my battery.
When connecting only one I don't have the 'precharge failure', but when using both I have.
Changing the precharge current parameter in the BMS ( configurable between 10A and 60A) doesn't seems to help, even if setting this to 60A
Seems my chargers don't take more then 0,5A in precharge mode ( this 0,5A is read from the BMS display), may be due to the construction of the inverters ( no direct connection to the capacitances, kind of MPPT system )
I'm not sure if this 0,5A is the real amperage they take or the average of a high frequency switched 60 amps ...
I can read on the display from the chargers that they just don't reach the total battery voltage ( about 15 volts missing from the 65 V to apply )
So apply just a bit longer the precharge current would solve the problem.
But I can't find a parameter to change the pre charge current apply time.
Does someone know if this apply time can be changed ? And if so how ?
Alternative would be to ask this at ANT themselves, but I can never where find a support contact ....
Thanks for any reaction !
