battery management system

hey hope everyone is doing great, my name is QIK I’m a student working on designing a motor system for an e-bike project. I’m seeking guidance on the best practices for motor control, selecting materials for motor components, and ensuring efficient power management. Specifically, I need advice...

Compliment of the season to you all. I'm new on this platform and this is my first question, hopefully someone will be of help. I have a project that I'm working on. It is a battery management system for bikes. We have a charging station which communicate on CAN rs458 protocol, but we recently...

I'm putting together a 12V 4S3P battery system with (3) HXYP_4S_3828_BMS battery management system modules, each managing one of the three stacks. Can I safely tie the three stacks together at the 12V terminal? My concern is that there may be a slight voltage difference between the stacks. The...

In short I'm trying to estimate the current draw in a remote weather station, to dimension its battery pack and solar panel accordingly. The way I'm thinking of involves writing down the current draw of the system every min and then multiply this number with 3600 to get the current draw for...

I using the MOSFET IRFB3004PBF switching. 56.2V is a source voltage coming from the charger and 48 is the nominal voltage of the batter. switch S1 is for switching Vgs. Vgs=5 v. Rgs=10k ohms (connected to the gate terminal and battery ground). battery is 13s3p Nominal=48v Peak=54.6v Will MOSFET...

I have a 13s bms laying around and I want to use it as a 7s bms, is there a way to do that?any suggestions would be greatly helpful.

Hello, I have lithium-ion battery pack that consists of 21 cells( 3 parallel,7 series,one of them 4,2V 3.4Ah). I use this battery pack with BQ7791504PW from Texas Instruments for battery protection.This IC achieves pack protection via CHG and DSG low-side NMOS FET drivers. I use this battery...

Hello, I apologize in advance for any grammatical errors. I'm working on a crowdfunding project that includes a small 5V motor (drawing 2A max) that needs to be powered by a rechargeable batterie via USB. Now I'm more into mechanic and such thing must be designed by an well trained...

Hello great team! I'd immensely appreciate the help of brilliant minds out here. I've Solar rechargeable emergency unit that can power 2 lights and a small table fan. The unit stopped working with a blown resistor on the circuit. I did try replacing the resistor with an identical color coded...

Hi, I am trying to set up the parameters for a LiFePO4 battery bank for a solar charge controller. I have tried to search the internet for understanding the basics of LiFePO4 battery but couldn't find any source from where I can understand the logics to calculate the parameters. So please pardon...
