Hello,
Sorry I forgotten it. Lipo for the 4s and 5s. And the battery of the car I really don't know what is the chemistry (it is a usual car battery). The current of the load will be about 10 A.
The tool recomend me BQ34Z100-G1. Could you help me…
Other Parts Discussed in Thread: BQ34Z100 Hello
I am using BQ34Z100-G1 to monitor the state of charge of a truck battery. The battery is 225Ah with max current of 1200A, although in practice it does not go beyond 300A. It is a 12-cell lead acid battery…

I am designing a battery pack composed of 15 series LiFePO4 cells, each one of 20Ah for a small UPS system.
As for the cell…
Hi Dan,
Impedance tracking gauge has higher accuracy. bq34z100-G1 and bq34110 both support Lithium Phosphate iron. bq34110 is CEDV battery gauge with end of service determination. If your care about is accuracy I suggest you use bq34z100-G1 which is…
Part Number: BQ76952 Other Parts Discussed in Thread: BQ34Z100-G1 We are in the process of developing a BMS design using the bq76952 (3-16 cell stackable) IC. We feel it is an extremely strong product. The plan is to use the IC standalone (for up to 48V…
Kaarel,
I checked the ChemID candidates with my program and I would recommend ChemID 435 over the others., becuase its OCV table has a better fit to your discharge data. We recommend that the %error be less than 10% for LiFePO4 cells, so you may want…
Hi Mike,
The active (recommended) devices for a 4S3P application are bq40z50 (Impedance Track) and bq3060 (CEDV). Impedance track is more accurate, while CEDV is quite a bit easier to grasp the concept and debug. Your capacity is in line with the design…
The bq34z100-g1 device has to be properly configured before it can report accurate state of charge readings. A few operations (e.g. programming chemistry id) can ONLY be done with bqStudio and therefore an EV2400 board is necessary since bqStudio has…
Part Number: BQ24133 Other Parts Discussed in Thread: BQ34Z100-G1 , BQ24172
I want to design a portable device, now choose 7.4V 2 cells 6000mAh lithium battery, the adapter input voltage is12V 3A, Can you recommend a suitable charging management chip…
thanks! I tried it. but it is still USB timeout . (win7 with win7 dirver)
We use the IC bq34z100. The application circuit refer the datasheet Figure 7. 1-Cell Li-Ion and 5-LED Display
Now,I suspect the EV2300 is bad, how can I test the EV2300 was…
