How to charge vechileBattery with smps



Unfortunately, a computer PSU (power supply unit) can not easily be converted to a battery charger by simply adding clips to the output and connecting to battery terminals. Doing so may cause burns, injury or explosion. Use of the correct charger will ensure a long, safe battery life. Read on for more battery information
Car Booster Packs may be suited for recharging via the small tabletop type automotive battery chargers. These chargers are probably cheaper than many computer PSU’s, and are designed specifically for automotive type batteries. Determine the cell or battery technology (if unable to transport) and consult a battery specialist (such as Battery Plus or Interstate Battery stores) for the suitability to task for this charger

VOOC Fast Charging Explain – What is VOOC Charge – How its Work ? 🔥🔌🤔🔋



VOOC Charging Explain – What is VOOC Charge – How its Work ? 🔥🔌🤔🔋

OPPO Super VOOC technology. Unveiled back in 2016, Super VOOC promised to top up your phone’s battery life in record time so that you never have to worry about plugging your device for prolonged periods. Let us talk more in detail about what OPPO brings to the table and how it could benefit future devices.

Super VOOC Relies on Higher Current to Top-up the Smartphone Battery Very Quickly

A power brick or wireless charging pad is used to charge the smartphone. As the majority of you aware, power is measured in watts and the more wattage being supplied to a smartphone, the faster it will charge. Lots of the smartphone chargers operate at 5V and supply a current of 2A, so multiple 5V x 2A and you get 10 watts of power. Super VOOC takes a different approach when it comes to fast-charging but if you read right at the bottom, the company approach has changed if you fast forward to 2018.
Using the same 5V voltage rating, the charger supplies current at 4A or 4 amperes, resulting in a total of 20 watts. This will certainly allow the smartphone’s battery to charge faster than before. also managed to point out that smartphone manufacturers often talk about a device’s capability of being able to take its battery from 0 to 80 percent or 0 to 75 percent in the shortest time possible.
Now, why is it that these manufacturers do not provide the total time it takes for a smartphone’s battery to reach from 0 to 100 percent? Well, that will result in a terrible marketing strategy and that is because a battery charging takes place in two stages; reach to a 100 percent takes a significantly longer, which is manufacturers do not want to point out this information
Stage one is where the battery charges rapidly from 0 to 80 percent, and what is happening here is that the charger is supplying a lot of watts to the phone, which would explain why these days, your device is able to come up to 80 percent of its total battery capacity in just 30-35 minutes. The drawback here is that the remaining 20 percent takes the most amount of time, and those details are purposely left out by manufacturers for the aforementioned reason.
Phones normally take much longer for their batteries to reach 100 percent, which is quite normal. However, there are certain properties of Super VOOC that are also beneficial for fast-charging smartphones.

Super VOOC Also Charges Smartphones Rapidly When You Are Watching Videos or Gaming

Though various fast-charging technologies have improved considerably, certain contingencies are present in devices in order to prevent them from overheating. For example, the processor running in the chipset clocks down (also known as thermal throttling) when the device’s temperature is reaching unacceptable levels. Similarly, if you are watching a video or playing an intensive 3D application on your smartphone or tablet after you plug in your smartphone, here is what you will notice.
When you are charging your handset, it will overheat and when you are attempting to charge your smartphone and play a video at the same time, heat is going to be generated from two different sources. At this point, the fast-charging feature of the smartphone shuts off and starts to charge normally in order to reduce those temperatures.

Fortunately, Super VOOC does the opposite and is able to retain lower temperatures while charging the battery rapidly at the same time. OPPO’s proprietary fast-charging technology charges at the same rate irrespective of the user playing an intensive 3D application or engaged in media consumption.

Super VOOC Technology Was Able to Charge OPPO’s Find X Smartphone in Just 35 Minutes

Wanna know a fun fact here? The OPPO Find X Lamborghini Limited Edition also utilizes Super VOOC technology and guess how long it took for the device’s 3,400mAh battery to get charged to 100 percent? Only 35 minutes. However, the company was able to achieve this by slightly altering its fast-charging technology. Instead of using 5V to charge the smartphone, OPPO achieved this through a voltage rating of 10V, which actually contradicts the original technology that was showcased back in 2016.
OPPO also stated during that time that 5V was actually beneficial for the phone because lower voltage not only offers lower temperature but it is also safe to use your phone while charging. It is possible that the company incorporated several protections to prevent irreparable damage from being inflicted on the ultra-expensive flagship, but it looks like we’ll be finding this out in the future.
According to the comparison seen in the image, it will take 220 minutes to charge on a standard 5V 1A brick to completely charge the OPPO Find X Lamborghini Limited Edition, while a common 5V 2A charger takes 135 minutes. With the current VOOC Flash charge, it takes just 90 minutes to charge from 0-100 percent but the new and improved Super VOOC is able to fully charge the device.
