Received messages from BMS siliXcon

These messages are for siliXcon BMS support. They are present if siliXcon BMS support is added to the firmware.

info

• All here listed messages are little-endian.
• This is not full documentation of all BMS messages. This is only for messages that are used by the LYNX application.
• These messages are used only if siliXcon BMS is enabled by /bms/bmstype = 1

0x500 - BMS status msg

This MSG is from siliXcon BMS. Timeout is set to 1000ms.

DNC - Do not care (not used) by siliXcon controler

Byte	type	Description
0	UINT_8	DNC
1	UINT_8	BMS driver state state < 90 - disarm state = 90 (overvoltage) - disable braking
2	UINT_8	BMS error word - If non zero, do disarm
3	UINT_8	SOC 0-200 = 0-100 [%] 255 = NaN (invalid value), than SOC is used from controller BEST
4-5	UINT_16	DNC
6	UINT_8	BMS suggested limit value for positive current (from the battery) 0-255, 255 = full current (no limitation)
7	UINT_8	BMS suggested limit value for negative current (to the battery) 0-255

tip

If you want to simulate siliXcon BMS communication, msg 0x506 and 0x507 are not required. But do not forget to set /driver/limiter/ibpos and /driver/limiter/ibneg to non-zero, otherwise, the BMS limit values are not used.

0x506 - BMS recommended limiter settings

If the value is 0, the limiter setting is not changed. The limiter setting are only applyed with first received message. This message is not ment for dynamic current limiting.

Byte	type	Description
0-1	INT_16	Ibpos [A / 10]
2-3	INT_16	Ibneg [A / 10]
4-5	INT_16	Ubmin [V / 10]
6-7	INT_16	Ubmax [V / 10]

0x507 - BMS recommended current setting

If the value is 0, the current setting is not changed. The current setting are only applyed with first received message. This message is not ment for dynamic current limiting.

This message only limit maximum values. If the actual value is lower than the limit, the actual value is used. No timeout on this message.

Byte	type	Description
0-1	UINT_16	Iref and Irefr limit [A / 10]
2-3	UINT_16	Ipeak limit [A / 10]
