Part Number:BQ40Z60
Hello,
I'm using a bq40z60 device and I noticed that whenever I turn on the charger's voltage supply (VAC), the internal temperature (which is also the cell temperature in my case) immediately rises by around 7°C. When I turn it off, it decreases by the same amount, also instantly. Do you have any idea why this is happening?
Thank you.
Regards,
Marie
