For Eltek, the standard ID is “0x305” and for Current Ways and Brusa the standard ID is “0圆18”. For example, on Elcon chargers the standard CAN ID is “0x1806E5F4” and “0x1806E9F4”. Locate the charge message or messages for your charger type. This will bring up the CANBUS message table. If in doubt, consult the charger manufacturer.įinally, click on the CANBUS Settings tab and click the “Edit CANBUS Messages” button. It is essential not to exceed the maximum DC amperage the charger is capable of outputting as this can cause certain chargers to enter an undefined state. Next, switch to the “Cell Settings” tab and change the value for “Maximum Amperage While Charging” to the maximum amperage (the amperage at which you want each charger to charge at multiplied by the number of chargers). (This step may also be completed using the “Profile Setup Wizard.”) This will enable support for a single charger.

It is important for each charger to see the correct amperage as some chargers go into an undefined state if they are instructed to charge at a higher amperage than their maximum.įirst, ensure you are working with an active copy of the profile (retrieve the profile from the BMS first if necessary) and enable support for the specific type of charger you have in the “3 rd party devices” tab. To address this, the “Maximum Amperage While Charging” parameter must be set to the maximum possible amperage for all combined chargers, and the CANBUS message table must be adjusted to transmit a value that is the maximum amperage divided by the number of chargers present, such that each charger sees the correct maximum amperage for a single charger. Additionally, when tapering the charge current at the end of charge, the BMS will not be able to calculate the correct amperage.

While this will appear to work out of the box without any changes, the BMS may throw an error code because it will observe a higher charge current than what it is sending to the charger. The BMS works with multiple chargers by sending the same CAN messages to the chargers. The profile will need to be transmitted to the BMS after changes are made.Ĭonfiguring parallel CANBUS controlled chargers: Set the “Maximum Amperage While Charging” setting (located under “Cell Settings”) to the maximum amperage of all chargers combined. The wiring for this varies based on the type of charger and the method used to control the charger.

Even if the charger manufacturer specifies it is okay to do so, series chargers have been known to produce very significant transients that may damage the BMS and other equipment connected to the battery pack.Ĭonfiguring parallel on/off style chargers:įor on/off chargers, simply use the charger safety output to toggle all chargers on and off at the same time. Important: Do not use the Orion BMS with chargers placed in series. Non-isolated chargers in particular may be dangerous in a parallel configuration. Important: Not all chargers can be paralleled safely! Consult with your charger manufacturer before paralleling chargers. The Orion BMS can be configured for this scenario. Some charger manufacturers allow paralleling two or more chargers together to achieve a higher charge rate. In some cases, it may be desirable to charge at a rate faster than one charger can handle.
