  • Forum Post: Re: Balance current in North and South directions and minimum voltage requirement for power pump to work

    PerBear
    Actually, the approx. 100mA balancing current that is possible with the reference design is suitable for most battery packs. According to a white paper about how much balancing current is required, this should be enough for packages up to tens of Ah as long as the cells in the battery package were initially...

  • Forum Post: Current measurement of bq78pl114

    Evgen Urlep
    Due to mechanical restriction it is not possible to set the current measurement shunt between Ubat- and PACK-, but only between V1 and V2. Seems that then the voltage shift of the current measurement is required. Are there any low power recomendation solutions. Is battery balancing and voltage protection...

    Nicolas TAUZIN
    My customer would like a battery with low power consumption and dicharge feature still active. Is there any solution to get a low power consumption (with the BQ29312 & BQ20z80) less than 60µA (Averaged) and voltage on the output ? The aim will to allow a dicharge, and so a wake up, without...

    Nicolas TAUZIN
    Hi, I did not found for BQ20Z80 the execution time for Voltage update, during SLEEP Mode. (SLUA380 Page 95) This information could be interesting in order to determine the average current versus the "Sleep Current Time" and the "Sleep Voltage Time". Thanks,

    I did not talk about the interval, i am talking about the execution time. For the current measurement (Page 95/232 SLUA380) : "It is imoportant to note for the settings of this register that it takes about 1 second to measure and update ..." For the voltage measurement (Page 95/232 SLUA380...

    Frank Thomas
    Hallo, I just got my bq20z65EVM board for evaluation. What I first did was that I connected a charged LiPo battery (2 outputs: +/-) to the 1N und 2P (and shorted the other 2P..4P) to pick off the respective voltage (8.2V) at the pack+/pack- connector but it didn't worked. So what did I wrong or...

  • Forum Post: Re: Use of N-channel power MOSFET on BQ78PL114

    PerBear
    500uA is probably too much, I would prefer less than 10uA. The worst seems to be max voltage: 16 cells have typical max charge voltage of 67 volt so the driver should handle at least 70 V continously and 100 V peak minimum. Unfortunately N-channel MOSFET drivers suitable for bq78PL116 seems to be scarce...
