The 218VBM provides a digital interface linking E-Plex to the precision BMV-60xS and BMV-70x ranges of battery monitors from Victron Energy.
The 218VBM connects to the Victron Energy BMV using its VE.Direct serial interface connector. Because the BMV is always powered, it accurately tracks battery status. The E-Plex interface reads the values from the BMV as they are currently displayed on the BMV screen. When connected, the E-Plex system is able to read the following information:
Name | Units | Type | Example |
---|---|---|---|
Voltage | Volts | 3 digits to 1dp | 24.1 Volts |
Amps | Amps | 4 digits to 1dp | 230.4 Amps |
Consumed Energy | Ah | 4 digits to 1dp | 1056 Ah |
State of Charge | Percent | 4 digits to 1dp | 87.2 % |
Time to go | Minutes | 5 digits | 13542 minutes |
Synchronised | True/false | 1 bit | true |
Notes:
The 218VBM incorporates galvanic isolation enabling the battery monitor to take measurements from a different battery bank to the one powering E-Plex. This also means that several 218VBM and BMV units may be connected to E-Plex to monitor several separate battery banks.
The 218VBM will operate with the following list of Victron Energy battery monitors:
BMV-600 series
BMV-700 series
It is important to note that the VE.Direct connector on the BMV-60x is not keyed which means the connector may be inserted either way around. If inserted with the incorrect polarity the BMV may be permanently damaged.
