Joulie-16 is the complete battery management system with Active Balance.

We use LEMM HASS 100 current sensors. Any equivalent type should work. Note that both + and - signals are required.

The relay is controlled by a pulse >50 ms, <100 ms for bi-stable relays. We recommend relays from LAYHER AG Type 400.

The BMS is able to measure 16 temperatures based on NTC 10, 3940. It comes with 4 RJ45 plugs, each for 4 external temperature sensors. You can use CellCon NTC boards on the cell connectors or place temperature sensors anywhere in the battery. The BMS also works without temperature sensors.

No. The Joulie-16 is intent to be used exclusively for 16S / 48V.

Use a terminal program such as TeraTerm, and the BMS Shell to change parameters.

If a CAN protocol to the inverter is necessary, no, since all CAN objects are equal. To build up larger systems with parallel memory blocks, use the UMC Controller (see below), which takes over the communication with the Joulie-16 and the inverters and controls the entire system on the battery side.

Joulie-4c (cascadable) is a 4S / 12V cascadable Active Balance BMS based on the same technique as Joulie-16. The use is intended for 12V batteries, 24V batteries up to 800V batteries. Joulie-4c is expanding our product portfolio in the direction of greater flexibility. Joulie-4c works as a MASTER / SLAVE concept. Each module operates independent of the MASTER, including voltage and temperature monitoring of the connected cells. MASTER and SLAVE communicate via a serial interface. In addition, an additional board CTRL may be connected, that takes over the communication via CAN with an inverter.
The MASTER has all the necessary outputs to control a relay, it also comes with galvanically isolated outputs Disable Charge / Discharge, and has an analog output for the SOC. The current sensor is also connected to the MASTER. So this is a 4S / 12V standalone BMS. See Joulie-4c documentation.
