BMS Configuration:

Settings can't be changed, please turn off first!

BMS Name : The Name displayed in the bluetooth connection dialog.
Enabled Inputs : If your BMS has more than one Relay, important that you set the right channels.	1 2 3
If a Device is powered with less parallel Batteries as intended, the Batteries can overheat and catch Fire!
Battery chemistry : The Battery Type is the chemistry of your battery. There are pre-settings for the Type. If you want your own settings Select "Pack V" or "Lithium" for more control.
Battery cells : How many of the cells of your selected chemistry your battery pack has in series.	S
Battery capacity : The Capacity of your Battery pack in mAh (total battery, not just a single strand)	mAh
Max. cell voltage : The cell voltage at which an over-voltage protection event is fired.	mV
Min. cell voltage : The cell voltage at which an under voltage protection event is fired.	mV
Pack under voltage : Under voltage Protection voltage for the whole battery pack.	V
Pack over voltage : Over voltage Protection voltage for the whole battery pack.	V
Discharge per Input : Max output (discharge) current of a single connected channel - if you want 300A combined output current and have all 3 channels enabled, this should be 100A	A
Charge per Input : Max input (charge) current of a single connected channel - if you want 99A combined charging current and have all 3 channels enabled, this should be 33A	A
Current imbalance : The difference in current that can flow between the batteries which will trigger a protection event. With identical battery packs, this current may be caused by different wire lengths or different stages of degradation inside the battery. This also checks for too high voltage difference before switching on. (max Difference = 0.5 V + 1 V per 10 A Imbalance Setting, so 40 A will allow 4,5 V Voltage Difference)	A
Detect Capacitive Load : If this checkbox is enabled the BMS will only turn on after precharging if you have a capacitive load connected. If precharge is instantaneous it will not turn on.
Shunt max temp : The shunt temperature can never exceed 110C°, otherwise the BMS will be damaged.	C°
BMS max temp : The BMS temperature can never exceed 90C°, otherwise the BMS will be damaged.	C°
Autostart : With this setting, you decide if the BMS should automatically try to turn on the channels on power up.
Auto power off : Idle time before BMS automatically turns off. Idle is defined as either not in operation mode or less than 0.5A drawn from each battery. Resets every time idle state is left.	min
Auto wakeup : enables the feature where the BMS wakes itsself up and goes to sleep again. Use the next two Settings to set the durations for that.
Wakeup interval : How long the BMS takes to go into Auto-Wake-Up to charge up your Phone-Display
Wakeup duration : this sets how long the BMS will be turned on (only the Power Supply, not the main contactor) after wakeup Interval wakes up the BMS	min
Data Frequency :
Update Count : The number of times, the configuration has been updated. This mostly serves as a confirmation that all of your changes have been correctly sent and read back— if you save the changes, this number should increase by 1.

Single Cell Monitoring:

Important Notes :

— This works together with supported isolated CAN-BMS Modules

— Configure the sequential CAN-Ids for each String (up to 3)

— Only use with additional Hardware Alert. CAN-Feature is only for DAQ

—After configuring, BMS requires a full restart to start the CAN bus

—Make sure you have the correct termination Resistors for your CAN bus

Input 1 :

First CAN ID : This will be the first CAN-Bus ID. The next 4 IDs will be sequential. For Example 54..55..56..57..58 if this setting is set to "54" (maximum 5 BMS Modules per String) This is also the same ID you will have to set in your EnnoidBMS or VESC BMS Module.

Advanced DBC Features:

In order to use CAN signals in a meaningful way, they must be converted into a human-readable format. This is achieved with the help of one or more DBC files that can be imported into the Voltaic Interface.

The values on the CAN bus are read according to the parameters of the DBC file. This means that they receive an offset, are scaled, the data type is taken into account and you tell the interface how many digits you expect so it can display the Value in the right format.

How to do that :

Based on experience, a DBC File has a hard life and sometimes does contain some intentional and unintentional errors, therefore we have left open the possibility to specify the parameters of the DBC file separately for the Voltaic Interface. This is done in the signal description of the individual signals; at any point in the description, a block with the following format can be inserted:

|Voltaic:[CONTENT]|

Where [CONTENT] should, of course, be replaced with your own content (without the "[ ]"). This content can contain one or more of the following parameters, each separated by a comma ( , ). The order is irrelevant:

name=[dataDistribution name for signal mapping]
type=[datatype]
factor=[factor to multiply with]
offset=[Offset (added after factor multiply)]
startBit=[Position of the first data bit of the signal]
unit=[unit shown in the gauges (max. 3 letters)]
displayName=[display Name inside the Gauges]
min=[minimal Value expected (example -99)]
max=[maximal Value expected (example 999)]
decPlaces=[decimal Places after the comma]

(the last 3 are important for the dynamic sizing of the values inside the gauges - default is 5 digits)
Example of a valid Block :

|Voltaic:name=signalXYZ,min=10,max=99,factor=2|

The parameters set in the “Voltaic Description” override the actual values of the DBC file in the Voltaic Interface. For example, if the signal is named “test333” and its description contains |Voltaic:name=test444|, the interface treats the signal as named “test444”. The same applies to all other parameters.
