The BMS Indication 2.x is configured over the CAN bus (P2, P3 or J1 headers can be used). The device is a slave in the CANopen network.

5

6

The default settings to connect to the BMS Indication 2.x are:

7

8

* CAN bus rate, kbps — 250;

9

* CANopen Node ID — 10.

10

11

To change the BMS Indication 2.x parameters use the ElectricDeviceMonitor software.

55

56

**//Indication options//** group contains the following parameters:

57

58

* Rotate LED indicator – a flag for rotating the 10-LED bar;

59

* Indicate overcurrent error – a flag for signaling about high current;

60

* Indicate overvoltage error – a flag for signaling about high cell voltage;

61

* Indicate Crown error – a flag for signaling about loss of communication with the BMS Crown;

62

* Disable LED indicator – a flag for turning off the 10-LED bar;

63

* Disable buzzer – a flag for turning off the buzzer.

64

65

**//Filters//** group contains the following parameters:

66

67

* Errors filter (all red segments) – errors that are indicated by flashing all red segments of the 10-LED bar;

68

* Errors filter (two red segments) – errors that are indicated by flashing two red segments in the middle of the 10-LED bar;

69

* Errors filter (two yellow segments) – errors that are indicated by flashing two yellow segments in the middle of the 10-LED bar;

70

* Errors filter (two green segments) – errors that are indicated by flashing two green segments in the middle of the 10-LED bar.

71

72

//Errors filter// for the four different color patterns is a 32-bit word which is written in the hexadecimal notation. Each bit of the word corresponds to an error. If the bit is set to “1”, the device signals about the error corresponding this bit. The list of bits and errors is in the table below.

73

74

|**Bit number**|**Error**

|**0**|Overcurrent

|**1**|Undervoltage

|**2**|Overvoltage

|**3**|Low DCH temperature

79

|**4**|High DCH temperature

80

|**5**|Battery cover is opened

81

|**6**|High humidity

82

|**7**|Water in the battery

83

|**8**|Logic high temperature

84

|**9**|Logic offline

85

|**10**|Critical error

86

|**11**|Crown error

87

|**12**|Cell count error

88

|**13**|HYG offline

89

|**14**|Not used (should be set to 0)

90

|**15**|Combilift offline

91

|**16**|Short circuit

92

|**17**|Contactor high temperature

93

|**18**|Logic count error

94

|**19**|ADC error

95

|**20**|Current sensor error

96

99

|**24**|Shunt error

100

|**25**|Settings error

101

|**26**|WDT reset

102

|**27**|No temperature sensors

103

|**28**|Temperature sensor is shorted

104

|**29**|Spirit offline

105

|**30-31**|Not used (should be set to 0)

106

107

For example, it is necessary to signal about the following errors:

108

109

* Low DCH temperature (bit 3);

110

* HYG offline (bit 13);

111

* Contactor high temperature (bit 17).

112

113

In this case //Errors filter// should be equal to the «22008» value. This value is calculated the following way:

114

115

2^^3^^ + 2^^13^^ + 2^^17^^ = 8,,10,, + 8192,,10,, + 131072,,10,, = 139272,,10,, = 22008,,16,,

116

117

If the value is set to the //Errors filter (all red segments) //field, the errors above will be indicated by all red segments of the 10-LED bar.

118

119

120

**//Low battery level signal (single beep)//** group contains the following parameters:

121

122

* SoC minimum value to signal – a charge level of the battery, upon reaching which a sound signal is emitted, %;

123

* Signal period – a period of the sound signal, second;

124

* Loudness – volume of the sound signal (Quiet or Loud).

125

126

**//Battery discharged signal (three beeps)//** group contains the following parameters:

127

128

* SoC minimum value to signal – a charge level of the battery, upon reaching which three sound signals are emitted, %;

129

* Signal period – a period of the sound signals, second;

130

* Loudness – volume of the sound signals (Quiet or Loud).

131

132

**//Charger connected/disconnected signal//** group contains the following parameters:

133

134

* Signal duration on charger connected – duration of the sound signal (one beep) emitting if the charger is connected to the battery, second;

135

* Signal duration on charger disconnected – duration of the sound signal (two beeps) emitting if the charger is disconnected from the battery, second.

136

137

**//Commands//** group contains the following parameters:

138

139

* Test LED indicator – a command for testing the 10-LED bar (all segments will be flashing red, yellow, and green alternately);

140

* Test buzzer – a command for testing the buzzer (loud signal, quiet signal and a pause will be emitted alternately);

141

* Reset and start loader – a command to reboot the device and start the bootloader for updating the firmware.
