Abstract

The present invention describes a system and a method for managing a set of batteries for an electric vehicle which comprises battery (B) reading cards (T) which comprise an A/D converter which converts the battery (B) voltages from analogue to digital, a plurality of power resistances which dissipate excess energy during balancing operations, and a microcontroller which controls the operation thereof; a coordinator (C) for battery (B) control cards (T) which is connected to the microcontroller of each battery (B) control card (T) and to a sensor (I) for detecting the current which passes through the batteries (B); and a bus (B) which has electrical isolation and interconnects the batteries (B), the controller (C) and the current sensor (I).
