For a basic setup you'll need an Arduino, a CAN interface and a relais to switch the 3MW signal.
If you want/need to measure cell voltages and temperatures with the Arduino, you will most probably need some analog input extension. A very simple and cheap setup for up to 16 cells is to use an analog multiplexer based on the CD74HC4067 chip.
Standard Arduinos can be powered from 12V, but will burn the voltage difference (convert to heat), so a step-down voltage regulator is highly recommended. The [Pololu A-Star SV series](https://www.pololu.com/category/149/a-star-programmable-controllers) has on-board step-down regulators suitable for a 12V supply.
Using an Arduino Uno style main board with shields reduces soldering requirements but needs more money and space than for example a Nano based board with break out components.
