GCE 1500V ESS High voltage lithium battery management system BMS quality long life solar energy storage system
Product system overview
Description
BMSs can also perform other functions such as cell balancing, which helps to ensure that all cells in a battery pack are charged to the same level, and fault detection, which alerts the user to any issues such as short circuits or open circuits in the battery system.
BMSs are essential for ensuring the safe and reliable operation of battery systems in a wide range of applications. They help to prevent safety hazards such as fires or explosions that can result from overcharging or overheating, and can also help to extend the lifespan of the battery by preventing damage from overcharging or overdischarging.

| 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
