mbed library for Texas Instruments bq76920, bq76930 and bq76940 battery management (BMS) ICs

bq769x0_mbed_lib's Issues

Add CRC check for cell voltage readings

Currently, CRC is only checked for single readings and not for consecutive reading of values from the register. However, the CRC for voltage readings should also be added.

Rework error handling (checkStatus method)

Rework should improve:

• Timer/interrupt handling: Clearing of error flags
• Current reading (see TODO in the code)

SAML21

Good afternoon,

I'm doing BMS 5S with SAML21. I can not build your library bq769x0.
Tell me which version mbed did you use?
Did you build the project online or mbed cli?

Thank you.
Andrew.

Optimized one-directional current management

If only one of the CHG/DSG MOSFETs is switched on, current goes through body diode of other FET resulting in high voltage drop and power dissipation on the FET.

Two solutions:

• Decrease current limit if only one FET is on
• Intelligent on/of switching to simulate ideal diode behavior

STM32 internal CRC calculation

Optionally, hardware-accelerated CRC calculation could be used instead of implemented function _crc8_ccitt_update
