4.5 DVCC Features when using CAN-bus BMS Battery

This chapter applies to all systems where an intelligent battery BMS is installed, and connected via

CAN-bus. Note that this does not include the Victron VE.Bus BMS.

Such intelligent BMS sends four parameters to the GX device:

Charge voltage limit (CVL): the maximum charge voltage that the battery currently accepts.1.

Charge current limit (CCL): the maximum charge current requested by the battery.2.

Discharge current limit (DCL): the maximum discharge current as requested by the battery.3.

For all three parameters, some types of batteries transmit dynamic values. For example they

determine the maximum charge voltage based on cell voltages, state of charge, or for example

temperature. Other makes and brands use a ﬁxed value.

Here is the page in the menus showing the parameters:

For such batteries, there is no need to wire allow-to-charge and allow-to-discharge connections to the

AUX inputs on a Multi or a Quattro.

When inverting, ie in Island mode, Multis and Quattros will shut down when the max discharge current

is zero. They will automatically start again as soon as either AC mains returns, or when the BMS

increases the max discharge current again.

All above means that setting up charge voltages or charge proﬁles in VEConﬁgure or VictronConnect

is not necessary, and will also have no eﬀect. The Multis, Quattros and MPPT Solar Chargers will

charge with the voltage as received via CAN-bus from the battery.

4.6 DVCC for systems with the ESS Assistant

The ESS Keep batteries charged mode works properly. It does not without DVCC.
