Battery cars to charge mobile phones or other digital devices, only need an electric car mobile phone charging converter to charge the phone. For example, as shown below ▼
Since the voltage of electric vehicles is generally 48V\/64V, the use of ordinary buck modules, such as the most commonly used buck regulator LM 2596 module, can not be used normally, only this converter can be used. And we only need Taobao search battery car mobile phone charging converter can be bought.
It is also very simple to use, such as the one in Figure 1. Its input voltage can reach between 36V-130V, it can be said that the voltage input range is very wide. Charging current is also a very important place to determine the charging speed of the mobile phone, this converter can provide 1A maximum 3.2A charging current, it is enough to meet our daily charging needs.
We can choose the appropriate output current converter according to our needs, the output current is different, its price is naturally different, and it has a digital display version. The battery voltage is also detected.
We only need to plug this converter into the charging port of the electric vehicle, if necessary, it can be fixed, plug in the data cable, you can power mobile phones and other electronic digital equipment. However, it should be noted that rainy days should not be used as much as possible, and it should also be unplugged to prevent water short-circuit damage.
If you are a scooter, its battery is DC12V, you can buy the following module to charge the mobile phone. The input voltage range is 6-24V, the long-term stable output current is 2A, the maximum current can reach 3A in the case of external heat dissipation, and the price of a treasure is about five or six yuan.
Connect two wires outside the battery car. The positive electrode is connected to the positive electrode of the module, and the negative electrode is connected to the negative electrode of the module.

There are two ways to charge your phone with a battery car:
First, connect a 48V to 5V voltage converter at the charging port of the battery car.
Second, buy an inverter to invert the voltage of the electric vehicle battery to 220v mains voltage, you can use the mobile phone charger to charge normally.
The mobile phone can not be directly connected to the electric vehicle battery for charging:
1, because the charging in the electric vehicle is directly connected to the battery and the mobile phone with the data cable, there is no mobile phone charger to stabilize the current, and the damage to the mobile phone battery is great.
2, and the electric car battery is generally 4, the voltage is 48V, the commonly used mobile phone charger voltage is 5V. Charging directly with the phone is not feasible, it will burn the power supply of the phone, and you need to add a 48V to 4V converter or power inverter in the middle.
If you want to use the battery of the battery car to charge the mobile phone, the simple way is to directly use the on-board mobile phone charging head of the commercially available electric vehicle, which can convert the battery voltage to 5V DC, and the output current can reach 1 ~ 2A, so that the mobile phone can be charged through the USB charging line.
The input voltage range of the car mobile phone charging head for the above electric vehicle is generally up to 36 ~ 100V, which is suitable for the battery car of 36 ~ 72V. In addition, the internal input stage of the charging head is generally equipped with an automatic polarity conversion circuit composed of diodes, which does not need to consider the polarity of the input voltage when used.
