In daily life, we are more or less in contact with the battery, many people can have an understanding of the types of batteries, but the internal structure of the battery cables knows very little, today let me take you to understand the relevant knowledge of the battery cable it.
The internal structure of the battery is more complex, composed of several systems, and the electrical system is one of the more important system. Battery cables are an important part of all battery electrical systems. The main function of the battery cable is to transport the current from the battery to the other systems. Therefore, the size of the battery cable is also one of the important factors affecting the amount of current when the battery works.
1. Amperage of current required to connect the appliances: As mentioned above, the size of the battery cable is associated with the size of the circuit current. And usually, the size of the circuit current is positively correlated with the size of the battery cable, i.e., the higher the amperage of the current required by the appliance, the thicker the battery cable.
2. Battery cable length: According to the actual situation, when the load appliance is farther away from the battery (i.e., the longer the battery cable is), the thicker the battery cable needs to be.
3. Battery voltage: in general, in order to deliver more power, the higher the voltage of the battery, the thicker the battery cables required, a simple understanding of the transmission of power, ten-volt batteries require battery cables than five-volt battery cables are thicker.
4. Battery cable materials: due to the different materials of the battery cable, the same size of the battery cable conductivity is different, naturally affecting the size of the battery cable. The stronger the conductivity, the thinner the battery cable needed. For example, copper is more conductive than aluminum, so to transmit the same amount of power, copper battery cables need to be thinner than aluminum battery cables.
Observe the picture below, you can find that the thicker the diameter of the battery cable, the greater the current it can carry, and the above content coincides.
1. Battery cable is too thick: battery cable due to material problems will have a certain resistance, when the selected cable is too thick, the resistance will increase unnecessarily, resulting in power loss. At the same time, the battery cable is too thick will appear bulky, not easy to transfer. In addition, it will increase the cost.
2. Battery cable is too thin: the current through the battery cable will inevitably appear heat phenomenon. If the battery cable is too thin, cannot meet the normal transportation of electricity, then the battery cable is forced to overload the transportation, heating phenomenon will be more pronounced, in serious cases, the battery cable shell may ignite, so that a fire.
Therefore, it is very important to choose a size to fit the actual battery cable.
1. Size of Battery Cables: When the materials are the same, the larger the size of the battery cables, the more materials will be consumed and therefore the cost will be higher.
2. The material of the battery cable: when the size of the battery cable is the same, the difference of the material becomes the main influencing factor of the battery cable. As the example given above, copper is more conductive than aluminium, but the price of copper is higher than aluminium, so the same size of the battery cable, copper cost is higher than aluminium battery cable.
