pin functions on a mobile application. Refer to section
9.1
for how to download mobile application.
Navigate to Configuration
→
Pin Functions and enable "AC Sense" function for pin "GPI1" and
"Enable Charger" for "GPO1". Dimensioning and selection of the electromechanical contactor and
other necessary components should be done according to the requirements of the particular system,
and is out of the scope of this document.
Note!
If voltage of the battery pack is greater than supply voltage of AC Power Relay, additional
DC/DC converter should be used.
2.3.2
CAN based charger
Provided wiring connection between BMS mini and CAN Charger in figure
2.9
is only for reference,
and should be done according to the general rules of correct CAN bus setup that are described in
section
4.2
. CAN charger is directly connected to a battery, but its control is performed over CAN
Bus. Wiring diagram is shown in figure
2.9
. Firstly connect battery to BMS mini: connect "Battery
(-)" to "Battery (-) terminal" and "Battery (+)" to "Battery (+) terminal" using power cables. Now
charger can be connected: using power cables connect "Charger (-) terminal" to "Battery (-)" and
"Charger (+) terminal" to "Power (+) terminal".

What is left is to wire CAN interface according to a CAN connection pinout shown in a figure
2.10
.
