Just casually want to learn about how ev battery works
Hi, We are working on EV Battery Management System. We wanted to analyse the data of EV BMS, like SOC (State of Charge), SOH (State of Health), Over temperature Protection Measurement, Current Measurement, and Voltage Measurement. Initially, we are looking for BMS Simulink, which we can consider as a prototype to analyse and run some algorithms on the parameters. Relevant Files are already downloaded in Matlab One Drive. Now, I just need to analyse the errors of the files executing. Attaching the Folder File link for your reference. Thanks BR, Yash Mittal
...delivery. I think t-test would do the trick. But i am not so sure since I am intererested if one pacemaker is destroyed, so it is rather not about the mean or median but about one to one...don`t know if that is understandable. Furthermore I would need some graphs afterwards, don't know if box-lot would be good? Here an example. pacemaker number one has a batterie span of 2.8V, after energy delivery battery span is still 2.8V... Would be happy if somebody could help me. Attached you find the Excel sheet. Here are the column numbers of the excel pairs that needs to be compared... I would really much appreciate a short description of what you did in SPSS for example.. Pairs: 1. Mittelwert RA (N=CD) 2.

Hi, I would like to install PV system with the battery storage. My power usage is quite high, so would like the system with the strongest possible panels, on the budget. Have two sunlight tunnels on the top roof which will limit panels space. Lower part of the roof is shaded, so would ideally need micro-inverters on that part. Not sure if is possible combination of micro-inverters and string inverter, maybe with optimizers?
I am developing a small headless windows computer to function as an automotive diagnostic tool. Using an ASRock Ind SBC-350M motherboard. Device will always operate on batteries. The motherboard has no battery management system. I would like a very simple way for a remote user to be able to see the battery voltage at minimum. It would be even better if windows recognized the battery as a battery. (Full battery management, cell balancing, control of charging strategy and current would all be a bonus, not required.) The mother board has GPI/O (Intel 300 series chipset family On-Package Platform Controller Hub) as well as RS-232/422/485. So how do we do it? Do you know how to program this? Does it require an additional device? Please help!
Hi Kostiantyn U, hope you keeping safe if you in Ukraine. I am currently working on a little project. It is a Raspberry Pi powered by SOlar / LiPro battery, a DC USB solar charger in between and a 4G hat for connection to the web. The goal for this unit is to take pictures from a river bank every hour, and upload them my server. I have built a prototype that is going on site in the next few weeks but the end goal is to combine all of these parts into ONE PCB along with the Pi and battery.

...will need to be a better design for the battery circuit. I require 2 to 3 amp output. I also need at least 1 amp charging and reverse polarity protection (without that dodgy IC (tp5100)) There is supposed to be a latching circuit for turning the device on. This works for turning it on, but there wasn't any way to unlatch the power to turn it off. Or at least the person I was speaking to stopped communicating to me to explain how this worked. 2) I will need a good latching power on and off circuit. I have two buttons available. Ideally, you would long press both buttons for power on. long press one button to turn off. 3) I no longer require all the extra pins. I only require pins for two rgb led strips, not four. I need the programming pins, battery and charging po...

...already). Features: 1) Always on display with black and white screen that say "Move me to start experience". White pixels should be used but all the black should be switched off. Main goal to conserve the battery life because phone will not have electricity for long time. It should work like Always ON Display but with different text (no clock or date ect) 2) It automatically switches off during night time from 23.00 till 7.00 and then switches on. When swithed on it should start straight away with kiosk mode and certain app should open (it will be 360 degree video experience) 3) If battery gets emty, it switches on as soon as USB charger is plugged in 4) Kiosk mode - when phone is switched on it enters kiosk mode straight away 5)On Always on mode it should detect...

...looking for something that is always on. I want the device to be in deep sleep mode so that it couldnt be found with a bug sniffer, unless the button was pressed. And then it activate, pull gps coords, send text to a group message between non-profit board, and security team. My knowledge of electrical engineering is minimal, I knew enough to build an ESP32 wifi button with a li-po rechargable battery, from following videos, for what I needed, but when it comes to cellular and researching there I am at a loss, and hoping for some help. I am currently in the proof of concept (proto-typing) phase, so that I can present a workable design to the board to get them to agree to implementing these for security purposes. Which means I'm working on my own budget. All that to say I do...
