【素人DIY】賢いバッテリーが届いたので、仕事に連れて行ってみた【LiTime】

Work by an amateur. I received a smart battery, so I took it to work. This is what I received. It’s a very smart battery. Let’s open it. You can access the battery information from the description, so if you’re interested, please take a look. This is the manual in Japanese. Product list. This is an advertisement. Warranty card. It seems to be a 5-year warranty. No volts left. Capacity is 12.8V 100A. This is not the lead battery that is generally used in cars. It is a type of lithium-ion iron phosphate battery, and it is not used to start the engine. As for what it is used for, it is often used as a power source for campers. People who fish can use it for electric outboard motors. It can be used for solar power generation and off-grid. It is also good as a sub-battery for truck lighting. As for what is smart, as it is written here, it is Bluetooth compatible. It seems that you can find out how much electricity you are using and how much electricity is left on your smartphone. The feature of this lithium iron phosphate battery is that it can maintain a high voltage until the end, which is what makes it different from a lead battery. Here is how to estimate the remaining battery power. At 100%, it is 13.33V or more. At 75%, it is 13.3 to 13.33V. At 50%, it is 13.15 to 13.2V. At 25% remaining, it is still 13V to 13.15V. When it drops below 12V , it is almost 0%. So even if you put on a voltmeter and check how much power is left, it is difficult to tell, and the voltage may suddenly drop. Since it maintains a high voltage until the limit, I think it is very good as a power source for mobile amateur radio operation. There is no loss of power at all. However, when it reaches the limit, the voltage will drop sharply. A feature that lead batteries do not have is that it has something called a BMS. A battery management system. That’s what it has. It protects against overcharging and over-discharging. What else was there? Cheating. Cheating. Protection from overcharging, overdischarging, overcurrent, short circuit, overheating, and low temperatures. Amazing. Low temperature cut-off protection. Lithium iron phosphate batteries should not be charged below 0°C. Charging is automatically turned off when it drops below 0°C. You can only discharge, not charge. Discharging is also turned off when it drops below -20°C. When the temperature recovers, charging resumes, maintaining optimal performance and lifespan. If you want to use it below freezing, there are heater-equipped versions. There are some cheap lithium iron phosphate batteries, but they don’t come with heaters or have features like charging stop below 0°C. I also like sleeping in my car, so I’ve had a sub-battery in my car for a while now, and I use lithium iron phosphate batteries. There was no built-in Bluetooth at the time. The battery I bought four years ago is still going strong. It was more expensive at the time. It was bigger. I have the same 100Ah battery in my car. It’s bigger and doesn’t have Bluetooth. I’m adding a fuel gauge. I think I’ll try connecting Bluetooth. It seems that you can get the app from Google Play Store. How do I connect it to the battery? I don’t know. Can I do it on my smartphone? My tablet is old and it didn’t work well. It worked well on my smartphone. It said to log in. Please enter your email address. A 6-digit confirmation code was sent to me by email. Enter a 6- to 10-digit password… Oh, you mean I have to do it myself? You have to decide on your own password. That’s right. Registration was successful. Add device. Scan the QR code. Connection successful. Oh. The current battery status is 20%. Does it show the battery temperature? Cell balance. There are about 4 single cells in this, which are connected in series to make 12.8V, and the balance of each single cell is good. The condition of the single cells is also good. The BMS, the battery management system, is also normal. Oh, that’s good. The voltage is 12V, but it’s already 20%. Let’s try charging it. You need a charger specifically for lithium iron phosphate batteries. Use the included volts. What about the plus and minus screen? Charging. 14.5A is going into the battery. 14.5, 14.8, 14.5 It’s going in at about 190W. If the charger had better performance, it would charge faster. I’m thinking about what to use this battery for. Maybe I’ll take it to work. I’ll take it to work and enjoy a cold drink because I have a car refrigerator. I’ll try running the refrigerator for a day. I installed a simple cigarette lighter. I put the battery at the passenger’s feet and put the refrigerator behind it. It’s big. Good morning. When I tried connecting the wires yesterday, it was at 99%. It ‘s almost fully charged. I made it easy to insert the cigarette lighter, so I’ll try turning on the refrigerator. 34°C. Really? I’m going to put in the drinks I bought yesterday at the supermarket. I bought too much. I’m not going to drink this much. It’s consuming about 40W. -3.2A. Discharging at 3.2A. I’ll also charge my camera from this battery. 3:30AM 28℃. It’s nice and easy to drive early in the morning. Be careful because deer often walk around here. Oh? What’s that? A turtle. There was a turtle. I hate when bugs fly around. I wonder how high the temperature will go today? I’m driving at my own pace, listening to music on a deserted road. From here to Tsuyama City. The sky is getting a little brighter. I’ll soon arrive at the first place (Kagamino-cho). 93% remaining, estimated remaining time 27.35 hours. Eh? Can it be used that much? Isn’t it strange that the refrigerator looks like 32℃? Yeah. I wonder. Loading. 5:30 Loading completed. 89% remaining. It’s pretty low. Good riddance. Oh, the temperature is dropping. 26℃. [Music] Yeah. It’s pretty cold. Hot. 5:30. Hot. Next, I’m going to Matsue City in Shimane Prefecture. If I go nonstop, it will take about 2 hours and 45 minutes. I think I’ll take a 40-minute break on the way. I’ll leave for 9 o’clock. I usually don’t stop at supermarkets, but I think I’ll buy some things because there’s a refrigerator. This store is open even early in the morning. I’m off. Chilled Chinese noodles for 110 yen, chocolate for 165 yen, cream puffs for 64 yen, sandwiches for 119 yen. Cheap. I probably won’t eat this much though. It’s okay if I end up taking some home. Because I have a refrigerator. Oh, it’s 6:20. If I make a detour here, I’ll be late. All aboard. Okay. The refrigerator was barely 20 degrees Celsius. Right now. Should I have chilled the refrigerator since yesterday? Mikame, Maniwa City. It’s 25 degrees Celsius by this point. It’s a little cooler after all. I entered Shinjo Village. There are no cars in front or behind, so it’s easy to drive. This is a prefectural border town. Once you cross here, you’ll be in Tottori Prefecture. The thermometer on the side of the road is 23°C. After passing the town hall, the climb up Yoju-magari Pass begins. I think this pass is relatively easy to drive on among the passes at the prefectural border. You can drive even when it snows. There is little traffic, so no one gets stuck. If you are alone, you can easily cross it. A six-wheeler with luggage is strong on snowy roads, so you can drive hard. When a cold wave comes, the scenery looks like this. Yoju-magari Tunnel. Why is the tunnel so wet in summer? Even if you wash your car, it gets dirty here. Only inside the tunnel is soaking wet. From the middle of the tunnel, you are in Tottori Prefecture. I wonder if the road gets wet because of the temperature difference? It’s wet all summer. Hino Town, Tottori Prefecture. I’ll use the toilet. It’s finally 17°C. Battery remaining is 83%. Estimated remaining time is 20.43 hours. 7:19. Outside temperature 32°C Kanemochi Shrine. The name is nice. After 8 o’clock, the number of cars increases. Passing the traffic light at Yonago Nishi IC. I have a lot of drinks, so I want to go to the toilet again after drinking a lot of tea. Turn left at the Kagetacho intersection. National Route 9. From here to Shimane Prefecture. 8:10? If I stop at the toilet at the roadside station there, it will be just the right time. There is a large roadside station here, so I will use the toilet. Yes. Thank you. The edge is free. I’m going to the toilet. Battery is at 79%. I turned on the refrigerator for just under 5 hours. Hmm, something is definitely wrong. Is the refrigerator broken? 39℃? Why? It’s cold inside. The setting is 9℃. Is this bad? It might freeze. There’s no way it’s 39℃. 28mhz is coming from Hokkaido. I’ll try transmitting at 430mhz FM. I ‘ll be on your frequency. Can you hear either of our call signs, JM4○○○? Good morning. JM4○○○, JE4○○○ Good morning. Thank you for your continued support this week. Yes. Thank you for your continued support this week. It looks like it’s going to be hot again today. . I can hear Hokkaido on 28mhz. Please. Understood. That’s right. I could only hear Hokkaido. We’ll be there soon. I’m unloading my luggage. Unloading. Unloading completed in about 20 minutes. Battery is at 77%. 44 degrees is strange. It’s going to freeze. Is it still okay? Well, I’m heading home. This is a drink I received from a viewer in Ehime. Thank you. It’s very cold. Ah, it’s delicious. I think I’ll turn off the refrigerator for about 30 minutes. It’s a little too cold. The oncoming car had a center loading antenna. I estimate the frequency with the antenna and imagine whether it’s CB or 28mhz based on the atmosphere of the vehicle. Is that 28mhz? Let’s call out to them. I’ll borrow the frequency from the passing car. This is JM4○○○. Can you hear me, the wing car with the blue cabin? Moving on Shimane Prefecture National Route 9. This is JM4○○○. Please. Was it wrong? Yes. AKI-san. Did you fix the radio? JM4○○○, JG1○○○ Saitama Prefecture. Yes. JG1○○○, ○○-san, Saitama Prefecture. This is JM4○○○. I just passed someone with a NASA mark, so I called out to him, but maybe I was wrong. You flew well. I transmitted at 4W without a booster. Please. Yes, I understand. I’ve been listening the whole time. The signal is good. Hmm? I thought it was me who passed by, so I asked, but I thought it wasn’t AKI-san. JG1○○○ moved to Saitama Prefecture. I enjoyed chatting with two stations in Tottori, Shimane, and Saitama for a while. After 10 o’clock. I turned off the refrigerator for about 30 minutes in the middle. The battery is at 74%. The refrigerator thermometer is broken, so I wonder why it’s 49 degrees Celsius. It’s really cold. I’ll have a sandwich. It’s really cold. I hope it’s not frozen. Somehow it didn’t freeze. It’s really cold. Okay, let’s go back to Okayama. I got back to Katsuyama, Maniwa City. It’s after 11:00 a.m. I can’t help but grab some snacks. The water is cold. Outside temperature is 39°C. I don’t know where the temperature sensor is in this car, but it gets hot when it stops. If I left any chocolate in the car at a time like this, it would all melt. It would be nice if we had a refrigerator. Loading is complete. Just before 12:30. After loading the luggage, we were given juice and ice cream. This is the true power of a refrigerator, isn’t it? Let’s put some ice cream in it. Battery is 74% remaining, outside temperature is 36°C. The rest of the journey is to drop off the passengers in Kita-ku, Okayama City. Go to Higashi-ku and drop them off. Return to Kita-ku once more to load up tomorrow’s luggage and go home. One more effort. Unloading is complete. Kita-ku. 13:28. Battery is at 70%. The ice cream is hard. Unloading in Higashi-ku is complete. Battery is at 68%. I wonder if it will fall apart? Let’s eat. It’s cold. It tastes okay. It’s only 100 yen. I wonder if it will taste good if I add mayonnaise? It’s okay for 100 yen . All that’s left is to load it tomorrow. Okay, let’s try one more time . Today’s mileage is 378km. I think I can drive about 50km more. Loading is complete. 4:30pm. Battery is at 60% . Estimated remaining time is 18.75 hours. Final loading is complete. I’m going home. Let’s eat some cream puffs and go home. Are we going to eat it all after all? I’m going home. I’m back at the garage. What do you think ? I’m a proper truck driver, right? You might be wondering who I am, but I’m not a stainless steel crafter. I ‘m a truck driver. Tomorrow’s destination is Kasaoka City. I think I’ll finish work early tomorrow, so I’ll get the oil changed. Oil change and grease up. Let’s do our best tomorrow. I went back to the garage. Battery is at 58%. It’s frozen. It’s good that the ice cream is frozen. Even the carbonated water has frozen. Oh. Yes. Thank you for your hard work. The battery is still at 55%. I’d like to use this battery a little more. A 2000W rated inverter. I’m going to try to run this thing with this . I removed the inverter I use in my car. It was attached with double-sided tape. It has a fuse. If the screws are loose, they will heat up, so I’d like it to be the type that can be tightened with a wrench. It might say “snap”. It’s not scary if you think it will say “snap”, but it’s a bit unpleasant. 13.1V Output 110V. Just by turning on the inverter, it sometimes flows about 1A and stops. The outlet plug for the air conditioner is here. It’s a simple portable power source. Cooling 25℃. 2.4A, 2.7A. Now, will it cool properly? 11A, 12A, 15A, 18A, 19A Over 300W. This battery is said to be good for up to 100A. Still 24A, 25A. It should be fine. Room temperature is 32℃. It’s getting a little cooler in the evening. 300W, it will run for about 2 hours even if I keep using it like this. It went to 400W. Is it okay? It’s stable at 530W, exceeding 500W. The camper trailer is narrow, so it’s below 30°C. It seems that it will run for another hour or so even if it continues to use it like this. Amazing. Of course, it can be charged with 100V at home, but it can also be charged from the car’s alternator. Leave the battery itself installed in a place where it won’t get in the way, charge it while driving, and use it when you need it. Without using the electricity of the main battery. If it’s a truck, you can use it for decorations such as lights. Of course, if you increase it by connecting two, three, or four in parallel or in series, the capacity will increase more and more. It depends on your ideas. 6:17 battery remaining 31%. Consumption is about 540W. The room temperature has dropped below 25°C. It’s a little warm. The battery is at room temperature. Normal room temperature. 50 minutes from the start. I thought about using the battery hard, but it will decrease when the room temperature drops below 25°C. The power consumption is 150W. The estimated remaining time is now over 2 hours. There is still 27% battery remaining. Is it okay to end the verification soon? What do you think? It’s an interesting battery, isn’t it? It’s easier than putting a generator in the car. It’s good that it can run home appliances even outdoors. How many times have it been charged and discharged? It seems to be over 4000 times. It can be charged and discharged a lot, so even if you charge and discharge it every day, it will take years. Yes, that’s all. I will put a link to the product in the description, so if you are interested, please check it out. The power consumption has dropped to 130W. It has become cooler.
