# dbus-serialbattery | ||
This is a driver for VenusOS devices (any GX device sold by Victron or a Raspberry Pi running the VenusOS image). | ||
This is a driver for Venus OS devices (any GX device sold by Victron or a Raspberry Pi running the Venus OS image). | ||
|
||
The driver will communicate with a Battery Management System (BMS) that support serial communication (RS232, RS485 or TTL UART) and publish this data to the VenusOS system. The main purpose is to act as a Battery Monitor in your GX and supply State of Charge (SoC) and other values to the inverter. | ||

## Developer Remarks | ||
### Developer Remarks | ||
To develop this project, install the requirements. This project makes use of velib_python which is pre-installed on | ||
Venus OS Devices under `/opt/victronenergy/dbus-systemcalc-py/ext/velib_python`. To use the python files locally, | ||
Venus-OS Devices under `/opt/victronenergy/dbus-systemcalc-py/ext/velib_python`. To use the python files locally, | ||
`git clone` the [velib_python](https://github.com/victronenergy/velib_python) project to velib_python and add | ||
velib_python to the `PYTHONPATH` environment variable. | ||
|
||
## How it works | ||
#### How it works | ||
* Each supported BMS needs to implement the abstract base class `Battery` from `battery.py`. | ||
* `dbus-serialbattery.py` tries to figure out the correct connected BMS by looping through all known implementations of | ||
`Battery` and executing its `test_connection()`. If this returns true, `dbus-serialbattery.py` sticks with this battery | ||
and then periodically executes `dbushelper.publish_battery()`. `publish_battery()` executes `Battery.refresh_data()` which | ||
and then periodically executes `dbushelpert.publish_battery()`. `publish_battery()` executes `Battery.refresh_data()` which | ||
updates the fields of Battery. It then publishes those fields to dbus using `dbushelper.publish_dbus()` | ||
* The Victron Device will be "controlled" by the values published on `/Info/` - namely: | ||
* `/Info/MaxChargeCurrent ` | ||
* `/Info/MaxDischargeCurrent` | ||
* `/Info/MaxChargeVoltage` | ||
* `/Info/BatteryLowVoltage` (note that Low Voltage is ignored by the system) | ||
* `/Info/BatteryLowVoltage` | ||
* `/Info/ChargeRequest` (not implemented in dbus-serialbattery) | ||
