GCE 1500V ESS High voltage lithium battery management system BMS quality long life solar energy storage system
Product system overview

Description
A battery management system (BMS) is an electronic system that monitors and controls the charging and discharging of a battery. It is typically used in applications where multiple batteries are connected in series or parallel, such as electric vehicles, renewable energy systems, and backup power systems.
Application scenarios
◎ PV power plant storage
◎ Island off-grid energy storage
◎ optical storage charge integration applications

RBMS Interface Description

No. | Name | Description | Precautions |
1 | B+ B- | Connect to the battery's total positive and total negative | Quick plug connection |
2 | P+ P- | Connect to the charging equipment (PCS) or DC bus | Quick plug connection |
3 | AC Input | The municipal power supply input port must be taken from the UPS/Inverter output side | 85~264VAC 1A max |
4 | ON OFF | ON: The circuit breaker is ON. OFF: The circuit breaker is disconnected | When the handle of the circuit breaker is in the trip state in the middle position, it needs to be turned OFF before it can be closed again. |
5 | D1 D1 D2 D2 | Two dry contact output reserved | The default D1 is charging prohibited, D2 is discharging prohibited |
6 | Start | DC start button: start the RBMS system By taking power from the battery side. | The system is connected to the battery, and after the circuit breaker is closed, press and wait until the light is on to indicate that the system is on |
7 | System | System status indicator | System normal: Green Alarm: yellow light Self test failure and protection status: red light Charging: green light flashes Discharge: red light flashing Self checking: red and green flashing alternately Pre-charging: yellow flashing |
8 | 1 2 4 8 | ID allocation: When multiple RBMS are used in parallel, the ID are allocated by setting the DIP switch. Must start at 1 | There are 4 DIP switches in total, supporting up to 15 RBMS in parallel 1 ON: ID+1 2 ON: ID+2 3 ON: ID+4 4 ON: ID+8 |
9 | TCP/IP | The RBMS host computer system software can be connected to the PC through the network cable | Network cable standard CAT5 or above, crossover cable or straight cable can be used, the line sequence can be according to the standard TIA-586A or TIA-568B |
10 | T-CAN T-485 | Terminal matching resistance setting during can and 485 communication Setting Description: (120R), on is valid | In parallel application, only the last one needs to be set. In stand-alone application, it can be used flexibly according to site conditions (interference, communication distance, etc.). |
11 | COM-IN COM-OUT | RBMS external communication port: When multiple RBMS in parallel: Communication with SBMS When RBMS Stand-alone: communicate with UPS/PCS external devices | The shielded twisted-pair cable harness must be used randomly. The cable sequence is defined in the cable harness label |
12 | GND HMI-B HMI-A 24V | 1.For external display connection 2.For powering SBMS | Please connect the display screen according to the silk screen sequence |
13 | BMU-OUT | Communication interface with BMU | Cascaded communication between BMU |
14 | ㊤ | RBMS chassis ground | Must be grounded, and the grounding resistance is less than 1Ω |
