EMS-CPU Product Description

EMS-CPU is the central processing unit (CPU) of the Energy Management System. It interfaces with sense boards (daisy chain) to obtain voltage and temperature data from each individual cell and it interfaces with shunt sensor to read pack current. The CPU is powered by a 12V DC source. It detects ground fault error, calculates the State-Of-Charge (SOC) of the battery pack, provides video output signal for display of pack voltage, pack current, SOC level, as well as alarm status. The CPU also provides alarm outputs for protection against over-voltage, under-voltage, over-current and over-temp conditions. EMS-CPU comes with three parts: the CPU itself, a shunt sensor and a computer cable connecting between the CPU and the sense board strings. EMS-CAN or EMS-MOD can be purchased together with EMS-CPU to add CANBUS or MODBUS communication capability for data extraction. Sensor board strings and an optional LCD screen are also sold separately.

Energy Management System (EMS) Overview 

The Energy Management System is designed for Li-ion battery pack using 20Ah, 40Ah, 60Ah, and 100Ah or 200Ah cells in series or parallel packs. The system components include a CPU, sense boards (connected as a daisy chain), a cable connecting the sample boards to the CPU, a shunt sensor, an optional LCD screen and an optional CANBUS or MODBUS communication interface. The features of the Energy Management System are: 

  - Designed for battery packs using 20Ah, 40Ah, 60Ah, 100Ah and 200Ah cells 
  - A distributed system measuring voltage and temperature of each Li-ion cell

MODBUS communication option

EMS-MOD Product Description:

EMS-MOD is a MODBUS communication option for the EMS system. It has to be ordered together with an EMS-CPU or an application package. A MODBUS communication board will be installed inside the EMS-CPU, and a MODBUS interface connection will also be added to the EMS-CPU for data communication. Available data formats are RS232 (default) and RS485.

EMS-MOD Product Specification:

  - This option adds an internal MODBUS communication board in EMS-CPU;

  - This option adds an external MODBUS communication port to the EMS-CPU;

  - This option comes with a matching female connector;

  - Output pins: TXD,RXD and GND (RS232); Data+, Data- and GND (RS485);

  - Input pins: Relay and Relay, which provides optional logic signal detection of open or closed circuit;

  - Default data format: RS232;

This item must be purchased with an EMS-CPU as a add on. If you already have an EMS-CPU you would like upgraded to have MODbus you will need to send in your existing CPU for installation.
