BQ76952 #17

Hi @martinjaeger ,

Do you have any plan to support BQ76952?

The BQ76952 has several differences from the BQ76940. The voltage and current measurement accuracy are improved, the measurement speed is much faster, the BQ76952 drives high-side FETs, it supports additional communication protocols, it includes automated cell balancing and automated FET control to recover from protection faults. If the BQ76940 meets your needs, it is a good device and may be simpler to understand its limited features. The BQ76952 is our newest industrial battery monitor with better performance and features.

TI

Yes, I am actually planning to develop a new BMS based on exactly that IC, but still need to secure some funding ;)

kidspro88 commented 3 years ago

Yep, sure, About the sponsor, can you contact me via e-mail?

martinjaeger commented 3 years ago

@kidspro88 I have dropped you an email on Friday (to the address I found in your commits, as there is no public email on your profile).

Let me know if you didn't receive it.

martinjaeger commented 3 years ago

@kidspro88 the mail I sent you just came back because of full quota. Can you please let me know your email address or contact me via martin at libre.solar?

We are currently applying for funding from EnAccess foundation to develop a BMS based on the bq76952. For anyone interested in such a BMS, please leave some feedback here: https://community.enaccess.org/t/open-source-flexible-battery-management-system-for-off-grid-energy-storage/75

The more feedback we get, the more likely it will be to make it happen.

Oops, didn't know that. A bit annoying for a community... I will send an invite to your email.

The bq76952 is already partly supported now and we are continuing to fully integrate it. Closing this issue.
