BMS Wi-Fi
General information
BMS Wi-Fi is an extension module that can be inserted into the BMS Mini 2, BMS Mini S, BMS Main 2.1, BMS Main 3, BMS Main X or BMS Main 3X controller. It allows a BMS controller to be configured over a Wi-Fi network and send battery data to a remote server.
Diagram of a battery system controlled by a top-level system over the Wi-Fi network is shown below:
Specifications
| Parameter | Value |
| Supply voltage, V | 5.0 ± 0.5 |
| Current consumption @5 V, mA (maximum) | 400 |
| Network frequency, Ghz | 2.4 |
| Supported network standarts | IEEE 802.11a/b/g |
| Dimensions (length × width × height), mm | 40 × 37 × 15 |
| Weight, g | 10 ± 5 |
| Operating temperature range, °С | -40 to +85 |
Installation
The BMS Wi-Fi must be inserted to the corresponding header of the BMS controller. Device must be fixed to the BMS controller by 10mm M3 standoffs and M3 screws.
Here is the example of header for additional devices on BMS Main 2.1:
Configuration
Configuration of the BMS Wi-Fi must be done according to the BMS controller’s configuration manual, see Battery management systems.
Typically, the connection settings are in the “Connectivity -> Wi-Fi” section of the settings.
