What are the normal 12V currents for cars?

Commonly used 12V batteries are divided into four categories: lead-acid batteries, nickel-metal hydride batteries, lithium batteries, and alkaline batteries.

Lead-acid battery (VRLA) is a battery whose electrodes consist mainly of lead and its oxides, and the electrolyte is a solution of sulfuric acid. In the discharged state of a lead-acid battery, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead; in the charged state, the main components of the positive and negative electrodes are both lead; sulfate.

The rated voltage of a single-cell lead-acid battery is 2.0 V. It can be discharged to 1.5 V and charged to 2.4 V. In applications, six single-cell lead-acid batteries are often connected. in series to form a standard battery. It is said to be a 12V lead acid battery, but there are alsoif 24V, 36V, 48V, etc.

For example: the car's 12V power supply can be connected to some external electrical equipment such as car phones, portable DVDs, mobile phone chargers, etc., which is more convenient to use. The car's 12V power supply is an interface that powers electrical devices outside the vehicle. Its output voltage is 12V and the current varies depending on different models.

12V power works by default for the cigarette lighter, and when we unplug the cigarette lighter and plug in the adapter, the 12V power has unlimited possibilities.

When the USB interface configured in the original car is busy and there is no place to charge the mobile phone, we can charge the mobile phone through the USB interface of the cigarette lighter adapter. At the same time, it can also power accessories such as recordsdriving urs installed subsequently. Since the cigarette lighter automatically cuts off the power after the car is turned off, it will not damage the battery when supplying power. accessories such as driving recorders.

Powering the “car kitchen and bathroom kitchen”

As people's demand for cars becomes higher and higher, automotive electronics manufacturers , in order to meet the needs of consumers, have launched such as well as car-mounted family kitchen and bathroom sets, such as vacuum cleaners, car refrigerators, and even car rice cookers. These products can be powered by the car's 12V power supply.

12V battery: According to the classification of materials, it can be divided into: 12V lithium battery, 12V lead-acid battery, nickel-cadmium metal hydride battery 12V, 12V alkaline battery.12 lithium batteries are composed of three 3.7V lithium batteries connected in series. The voltage of a single lithium battery when fully charged is 4.2 V, usually also called 4 V. The voltages of the batteries connected in series are added together, which is: 4 V/. battery*3 Personal power supply = 12V, which we call 12V lithium battery. The combination is as shown in the figure below
