    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

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.

    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.
