I'm looking throw bq76940 datasheet and I've found such connection of sense resistor:

Sense resistor connection

What is the purpose of the additional resistors and capacitors? Why all 3 capacitors are required?

    I think noise filtering. It will avoid controller from doing weird things if current is drawn in pulse from the battery. – Indraneel Aug 03 '19 at 20:49

It's a lowpass filter. It filter out common mode noise (resistors and those capacitors connected to the earth) and differential noise (mid capacitor and resistors)
