  • Regarding usage of LTC2944

    I am designing electric circuit for an electric vehicle with a battery of 48V &130ah capacity. I need to measure state of charge of battery, so i decided to  use coulombic counting method to do that. So, i have chosen LTC2944 chip for my application…

  • LTC2944 and Arduino compatability

    Hello,

    I am currently working on a coulomb counter/battery gas gauge for my senior design project. The battery we are using is a 36V, 20Ah Li-Ion battery (8 - parallel, 10-series) that will be dissipating 5A max. We want to use the LTC2944 battery gas gauge…

  • LTC2944 Corrupted Control Register

    I am using the LTC2944 in a low power device to monitor battery discharge of primary cells.  In my design the Gas Gauge is always powered.  However, the 3.3V supply that biases the pull-ups on the I2C signals is not.  In order to conserve energy, the unit…

  • LTC2944 battery gauge problem

    Hi,

    We have a problem calculating the percentage of the remaining battery. We are currently using a raspberry 3b + with a 4cell battery of 2200mA, with a Rsense of 50mOh and a Imax of 1500mAh.

    We tried to make the calculation of the page 11 in the manual…

  • LTC2944 Voltage Reading Anamoly

    I have a setup where I use the LTC2944 to monitor the battery voltage and the output of which goes to the microcontroller so I can use data logging to monitor the voltage and log in every second. I have used this setup successfully from -40C to 21C without…

  • How to calculate charge with LTC2944 ?

    Hi, 

    I'm using the LTC2944  and I found the linduino file cpp but i don't know how to use it to calculate the Charge in Coulomb and in mAh. There is no time consideration in the code ? 

    Thank's for help !
