how does a 12v voltage gauge work on a kayak
How to correctly check and understand the voltmeter of a kayak 12v voltage gauge is divided into the following steps:
1. Setting parameters: 12V battery, 12V for charging, and about 13% of the battery capacity for current.
2. At the initial stage of charging, the reading of the voltmeter is the current voltage of the battery plus its internal resistance voltage drop, which may be less than 12V, and the current is the set current.
3. In the middle of charging, the voltage increases with the increase of charging time, and the charging current decreases.
4. In the later stage of charging, enter the so-called "trickle" charging process, the voltage will be close to the battery charging termination voltage of 14.4V or even exceed this value (caused by internal resistance voltage drop), and the charging current is close to 0. At this time, the charging can be terminated.
The 12V voltmeter gauge is suitable for charging 12V and 24V batteries. The bowl also has the function of anti rearconnection. However, there's no voltage affair, If it isn't connected or the opposition is rear connected. It can work typically only if it's connected rightly. It also has the protection of overvoltage, overcurrent, overheating and so on. The principle of charging is that the voltage of the bowl is advanced than that of the battery before charging. The lesser the electromotive force difference between the two, the briskly the charging and the lesser the charging current. Thus, the maximum voltage (no- cargo) of the general 24V bowl is 28V, while 60A refers to the affair current capacity of full cargo. When you charge, the bowl has a cargo. At this time, the voltage is the charging voltage of the battery, and the current of 40A is the charging current. This current will come lower and lower with the completion of charging. In addition, the charging current is also related to the capacity of the battery .
For a 12V voltmeter, if it is a pointer type, it only needs to be connected in series at the negative pole of the circuit. A shunt is required for high power. Digital generally has four wires, two in and two out, which are also connected in series in the circuit. At the same time, the instructions for use should be obtained from the merchant at the time of purchase.
