Answer “REC - BATTERY
MANAGEMENT SYSTEM”
First answer is 28 –how many byte
data will be sent and then data
message follows as 7 float values:
LCD1 [0] = min cell voltage,
LCD1 [1] = max cell voltage,
LCD1 [2] = current,
LCD1 [3] = max temperature,
LCD1 [4] = pack voltage,
LCD1 [5] = SOC (state of charge)
interval 0-1-> 1=100% and
LCD1 [6] = SOH (state of health)
interval 0-1-> 1=100%
First answer is 8 –how many byte
data will be sent and then data
message follows as 8 byte values:
LCD3 [0] = min cell BMS address,
LCD3 [1] = min cell number,
LCD3 [2] = max cell BMS address,
LCD3 [3] = max cell number,
LCD3 [4] = max temp. sens. BMS
address,
LCD3 [5] = max temp. sens. number,
LCD3 [6] = Ah MSB,
LCD3 [7] = Ah LSB
BMS first responds with how many
BMS units are connected, then it
sends the values of the cells in float
format
BMS first responds with how many
BMS units are connected then it
sends the values of the temperature
sensors in float format
Cells internal DC resistance
BMS first responds with how many
BMS units are connected then it
sends the values in float format
BMS first responds with value 1, then
it sends the values of the BMS
temperature sensor in float format
Error number description
array
First answer is 4 –how many byte
data will be sent and then data
message follows as 4 byte values:
ERRO [0] = 0 –no error, 1 –error
ERRO [1] = BMS unit
ERRO [2] = error number (1-14) and
ERRO [3] = number of the cell, temp.
sensor where the error occurred
