GCE BMS 68S 50A High Voltage BMS for Solar Power Storage

$651.00

The case-type all-in-one integrated BMS is composed of BMS main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, micro-break switch, power connection terminal, structural box, and wiring harness. The most striking characteristic of the BMS is combining the main control board, sampling board, and other power devices integrated into one, keeping the system as a secondary structure. It has the characteristics of compact structure, flexible installation and low cost. It is suitable for use with larger capacity batteries, such as 50-100ah batteries, and the battery module and BMS are installed separately.

BMS OVERVIEW

  • The case-type all-in-one integrated BMS is composed of BMS main control board, BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, micro-break switch, power connection terminal, structural box, and wiring harness. The most striking characteristic of the BMS is combining the main control board, sampling board, and other power devices integrated into one, keeping the system as a secondary structure. It has the characteristics of compact structure, flexible installation and low cost. It is suitable for use with larger capacity batteries, such as 50-100ah batteries, and the battery module and BMS are installed separately.
  • Especically suitable for off-grid solar PV energy storage applications where there is no communication protocol in BMS and inverter;
  • Each 15S is a battery collection unit, that is total of 4 collection units in a 60S batteries; total 5 collection units in a 75S batteries;
  • Every 15S coming with 3 temperature acquisition probe, so 60S total 12 temperature acquisition probe; 75S total 15 temperature acquisition probe;
  • Hall sensor is used for current acquisition, which is safe and reliable, no heating;
  • SOC estimation error ≤5%;
  • 3-digit address dial to set BMS address;
  • 2-channel relay dry contact output;
  • 4-channel contactor expansion and auxiliary contact detection;
  • Provide host computer software, which is convenient for customers to debug the battery system, and can also modify system parameters through the host computer

EQUALIZATION FUNCTION of BMS

BMS adopts the method of resistance bypass to balance the cells. The cell voltage of the battery pack reaches 3.5V and the voltage of this cell is 50mV higher than the minimum single cell

voltage, or the cell equalization function is turned on when the cell voltage exceeds 3.65V; it enters the protection state (except for overcharged and fully charged states), the equalization

stops. Note: Equalization voltage can be set.
