I can confirm it works with a Spark and a Mini2. I was hoping it would read the FPV batteries but I think the BMS used in that is a variation on a theme. I can get a response from the battery but very little in the way of a sensible output.
I am having the same issue, went to settings battery usage, and it reported the HomeKit widget was consuming 30% of my battery. I removed the widget, it's much better however still in early beta drain land.
I investigated the issue and found out that the mail app drains the battery 100% when charging / at night.Later on I found out that actually the consumption rate is equal on the rest of the day, but due to the fact that I'm using other apps, the battery consumption is shared between them.
I have a Iphone 14 , 6months old and recently upgraded to ios17 beta. The moment, i installed it I have started facing problems in battery. It is draining very fast within no time. earlier when i was using ios16, my phone's battery used to last 1 day or more than that but now ends in half a day.
I currently have the same problem with an iPhone 14 Pro and 100% battery capacity/health.As if that wasn't enough, I'm seriously worried about the heat generated by the battery. The iPhone is worryingly warm.
Option 1: If this works, you will get a read out of the stats from your battery. This will include cycle counts, temperature, current voltages etc. It should look something like this:
I don't think the charger really puts that much heat into the battery from what I've witnessed. The charger module itself generates quite a bit of heat because its only about 90% efficient. So you're getting 300W+ lost as heat. Thats likely most of the heat. If you think about it only 11A of current approx go into the battery when charging at 3.3kW. If you compare, the motor can pull around 200A at full electric throttle and regen about 120A. Just to maintain 45mph flat pulls roughly 50A! That generates WAY more heat then the charging at 11A.
I wish they would run the battery fan while the car was plugged in and not charging. Keeping the HVB cooler would really help when you go to drive later. Just sitting in the heat after the battery is already hot from driving does not help...airflow would help that. I've noticed it will run the fan if its set to value charge and waiting to charge BUT it won't suck air from the outside. Only from the trunk.
I've been thinking about making a PWM controller to run the fan the way I want it and just feedingback what the BECM expects the cooling fan to be at. Just gotta be able to open that door too to allow air in from the inlet behind the bumper. If I ever have the time to do it I'll happily sell some to whoever wants better battery cooling.
My thoughts exactly. I also agree on the charging heat... except that, like you already said, the fans are running the entire time the charger is going. If I know I'll need the range I'll use 240v at home. If the car is in the garage for the night, I'll use 120v. Also, over the last several days, I've been doing some testing on how to keep the battery below 105F, yet still do 41 EV miles/day. It's by far the hottest time of the year here in Utah. The last two weeks have seen 95 degrees + mid-day. At night, the temperatures get down to the 70's usually. I used 120v charging last night, this morning the pack was at 91F (hot from yesterday). Pure EV on the highway all the way to work. Arrived at work with 4% left and a 99F HVB. I plugged it in at work (120v). Torque seems to read the SoC and HVB temp even while the car is off, so long as the car is plugged in. So from my office chair, through the window I could monitor the temps. As the SoC climbed, the temperature actually fell down to about 98F. Battery full just after lunch, ambient air temp is well over 95F as well... I unplug the car and park under a tree and put up the sun shade in the front window. From about 1:00pm to 3:30pm, the HVB temperature climbed from 98F to just over 99f. Now, the interesting part... I left work in EV mode to get out of the business park. Just before I got on the highway, I kicked it over to EV later... let the engine warm up, then blasted the AC while I was getting up to speed on the highway. I ran in EV later mode for probably 4 miles. As soon as the climate wound down to
I mentioned this idea in another thread but I just saw something that kind of works the way I was thinking. Use a long hose to take AC from the rear vents to the parcel shelf air intake for the battery
So... interesting thing I discovered this week. If the battery is warmer than it should be, the cooling fans stay ON when the car is plugged in, even if I have it set to value charge later. My intention was to let the batteries cool down in the driveway, then charge after 11:30pm. The cooling fans seemed to run from about 4:00pm to 8:00pm, even though it wasn't charging. I have an ammeter to track Kw/h usage for the outlet, and it was pulling about 0.5a at 120v even though it wasn't charging. If I'm not lazy, I may try to figure out at what temperatures the cooling fans will run when value charge is enabled.
By EV miles, I meant to say that I can do a full charge 2 - 3 times daily if you are strategic about charging and parking your car in the shade and still keep the battery at a sane temperature (goal of less than 105F)... Not that I am getting 40-60 EV miles per charge. I drive a good amount of highway, so I'm getting the standard 18-22 miles depending on speed and HVAC use. :)
I built several LiPo dischargers in the past but all are designed to fully discharge batteries, and none have the ability to stop at a certain voltage. The URUAV LiPo Killer is a cheap and smart battery discharger which can do that.
Why discharge LiPo to 3.8V per cell? 3.8V is the storage voltage for a LiPo battery cell. Leaving your battery fully charged or empty for too long can accelerate performance degradation. When you are not using the LiPo over a long period of time (i.e. a month) you should put it in storage voltage (i.e. 3.8V per cell).
DJI drone batteries are considered intelligent Batteries because they have advanced features like a Battery Management System (BMS) that monitors key parameters like voltage, temperature, battery health, communication with the drone, safety mechanisms, hibernation mode, and optimized design.
To connect the interface to the battery, connect the ground pin of the interface chip to any negative terminal of the battery. Connect the SDA and SCL pins correspondingly to their respective points on the battery terminal.
Your new iPhone 12 or Samsung Galaxy S21 probably had tremendous battery life during its first month of use. But slowly, battery performance has likely started to wane. Turns out, much of that could be dependent on the apps you have installed. And no, it's not just Tinder or Facebook.
The folks over at pCloud, a cloud storage company, analyzed 100 of the most popular apps to see which were draining battery. While social media apps were obvious contenders for lithium-ion lessening, there were some more benign apps that most would probably never suspect.
When ascertaining an apps battery usage, pCloud looked to what functions an app might deploy, such as location or camera. pCloud would then assign a figure to each function for battery draining potential and would apply those metrics to each app. The company also was on the lookout for battery-saving functions such as dark mode. It was by evaluating these metrics that pCloud listed which apps would likely even choke devices on our best phone battery life roundup.
Leading the pack was surprisingly Fitbit. The fitness band used 14 out of 16 available background functions, including the four most demanding. These include camera, location, microphone and Wi-Fi connection. Following Fitbit was another surprise entry, Verizon. Yes, the app that you can use to pay your Verizon bill could eat more battery than Uber, Skype or Facebook.
Generously, pCloud also included a breakdown of the top-50 battery-draining apps. Some notable apps include McDonald's, Reddit, Netflix and TikTok. Duolingo, with it's daily notifications, also lands in the top-50. Weirdly, so does online payments company Klarna.
Beyond battery life, pCloud also found that travel apps eat the most amount of internal phone memory. Here, pCloud is essentially comparing the size of apps. United Airlines takes the top spot for using over 400mb of memory, with Lyft and Uber following behind. And it's not just going to places that will eat up battery life, so too will delivery apps that bring you your food.
