If the voltage of the tram battery is too low, you can add a little electrolyte first, and then use the charger to charge it. Or go to 4s for repair.
Voltage, also known as potential difference or potential difference, is a physical quantity that measures the difference in energy produced by a unit charge in an electrostatic field due to different potentials. Its magnitude is equal to the work done by a unit positive charge moving from point A to point B due to the strength of the electric field. The direction of voltage is defined as the direction from high potential to low potential. The international unit of voltage is the volt (V, called volt). Commonly used units include millivolt (mV), microvolt (μV), kilovolt (kV), etc. This concept is similar to “water pressure” caused by water level. It should be clarified that the term “tension” does notis generally used only in circuits, while "potential difference" and "potential difference" are generally used in all electrical phenomena.
The Junfeng E11K is a compact car owned by Dongfeng Motor.
The starting voltage of the Dongfeng Junfeng is 12 volts. In fact, the electrical systems of most cars operate on 12 volts. The voltage of 12 volts is widely used in automotive electrical systems for the following reasons:
1. Compatibility: 12 volts is a standard voltage for which most automotive parts and equipment are designed for 12 volts. This includes starting systems, ignition systems, lighting systems, audio systems, etc. The adoption of a unified voltage standard guarantees compatibility and interoperability between different components.
2. Reliability: The voltage of 12 volts has been widelyverified and used in automobile electrical systems and has high reliability and stability. Most car batteries and generators are capable of providing a stable voltage of 12 volts to keep the system running smoothly.
3. Economics: 12-volt electronic components and electrical equipment are relatively common and economical, and their manufacturing costs are relatively low. At the same time, it is relatively easy and economical to repair and replace parts related to the 12 volt voltage.
It should be noted that although most cars use 12 volts, in some special applications, such as large utility vehicles, military vehicles or special vehicles, electrical systems with other voltage levels can be used. Extended Content: In the field of electric vehicles, due to the need for powerhigher output, higher voltage electrical systems are typically used, such as 400 volt high voltage systems. This reduces current size, reduces energy loss and line thickness, and improves overall efficiency.
