Part Number: BQ34Z651 Hi There,
I am writing my own script to update the data flash on my BQ34Z651 devices and I have noticed that there are many regions of the data flash that are undocumented.
So far I have discovered the following:
SubClass ID

Part Number: BQ34Z651 Hi There,
I am having an issue whereby charging is being prevented when I reach a high SOC (>95%). The result of this is that it is impossible for me to fully charge by battery. I have verified (both in the registers and on the PCB…
Part Number: BQ34Z651 Other Parts Discussed in Thread: BQEVSW , GPCCHEM , BQMTESTER Hi Everyone,
I am testing out a system I have designed using the BQ34Z651 and I have triggered a SafetyStatus Fault (AOCD) and I do not seem to be able to clear it.
Is…
Part Number: BQ34Z651 Hi Everyone,
I have two 4 cell packs that seem to have the same issue wherein there is a permanent failure CIM_A that I cannot clear. my CIM_config is as follows:
Active CIM Fail Voltage = 800mV Active CIM Time = 5s Active CIM Check…
Hi,
The TRM in your link is BQ34Z653, not BQ34Z651, please check you have use the right document.
The make the Coulomb counter accurate, a good chosen value of sense resister and the good PCB layout is very important to achieve this.
Other Parts Discussed in Thread: BQ34Z651 I seem to be unable to get the heater control to work with the BQ34Z651.
I am cooling temperature sensors to be well below the trip point set in the data flash but the GPOD output never switches and therefore never…
Other Parts Discussed in Thread: BQ34Z651 Hi Everyone,
I am having an issue where sometimes the BQ34Z651 changes the Full Charge Capacity to a value much smaller than what it should be (17000mWh vs. 84000mWh). This has the roll-on effect of causing charging…
Other Parts Discussed in Thread: BQ20Z65-R1 Hi Everyone,
I was just wondering if there is a reference that details how the DataFlashSubClassPages (SBS Commands 0x78..0x7f) correspond to the data flash values that I can alter in the Evaluation Software…
Other Parts Discussed in Thread: BQ40Z50-R1 , BQ34Z651 , BQ34Z653 I want to use two of these devices in parallel battery packs. Can I change the Address one of the devices?
If not, How hard is it to compile a new firmware with that very simple change?
I am having an unusual issue where the fields 'Charging Current' and 'Charging Voltage' remain at zero when charging and only gain a value during discharging.
This is causing the charge to terminate earlier than i would like it to as two…
