FAQ
1.
Q: Can the 485 version and CAN version of the V14 BMS change the baud rate of the BMS by refreshing the program?
A: NO, they are different version of the chip.

2.
Q: Is it an equalizing function, active or passive and what is the equalizing current?
A:It's a passive equalizing function with 150mA current.

3.
Q: What is the connection mode of communication when BMS communicates with inverter or 485 communication and CAN communication?
A: External communication means that BMS is connected to CANBUS interface when communicating with inverter (RS485 interface is used for communication with Voltonic inverter)

4.
Q: The BMS cannot work and indicator does not light up.
A: May be caused by D4 diode damage.

5.
Q: Which BMS model suitable for ternary lithium battery?
A:The ternary lithium battery can support up to 14S version of the BMS. The firmware version of the ternary lithium battery BMS is different from the lithium iron phosphate BMS and cannot be used universally.

6.
Q: Voltronic inverter and its licensed inverter only have 485 communication version of BMS or new version of BMS (V16 version). How to use the inverter?
A: The Voltonic inverter uses RS485 interface for communication. DIP dialing is different from other versions of BMS. Connect and dial 1on to the host, 2on to the first slave, and 3on to the second slave. You can ask me to send relevant documents.

7.
Q: How is BMS function of SOC calculating and cycle life counting work?
A: First, modify the rated capacity of the battery, then complete a full charge and discharge process,the actual battery capacity will be learned.SOC is calculated by capacity accumulation and voltage calibration.
  It has the function of calculating the number of charging and discharging cycles. When the cumulative discharge capacity of the battery pack reaches the set full capacity.At 20% (default), the number of cycles increases one,the set value of battery cycle capacity parameter can be changed through the upper computer.

8.
Q: The issue of battery monitoring software cannot see the master when multiple BMS are in parallel.
A:When multiple BMS are in parallel, the battery monitoring software cannot see the information of the master, only see the information of the slave. If you want to see the information of the master, you need to turn off the DIP of the master and connect it separately or use the LCD screen with Bluetooth function, or use the onboard BMS with Bluetooth function.

9.
Q: Why not message display on LCD screen?
A: 1.The function of LCD did not open.
    2.Poor contact of connecting or broken wire of LCD screen.
    3.The new version BMS with Bluetooth, but install with an LCD screen without Bluetooth.

10.
Q:limited algorithm of charge current.
A:Unbalanced in current distributed.
1.no charge current if any device is in charging warning of voltage,temperature,and capacity or charging protection.
2.charge current values remain in 10.0A when no device in charging.
3.charge current is base the role if over current is greater than 20.0A then reduce 10.0A,otherwise,remain in 10.0A when single device is charging.
4.charge current is base the role of over current value multiply by device's quantity then divide by two if more than two device is charging.
5.charge current will be cleared and set the chargeable value to 0A when any single cell voltage more than +30mV compare to over voltage protection value with battery pack in parallel.

11.
Q:what if customer want to purchase BMS but the inverter in use is not in compatible list.
A:Customer need to provide the communication protocol of their inverter.

12.
Q:Battery monitoring software not working or load protocol failure.
A:1.Download new program.2.set the correct format language(as below)
