2000 divided by 48 volts equals 41.6 amps. If you use a 200-amp-hour battery, you need one-tenth of the standard charging current, which is 20 amps. The existing 48 volts * 41.6 amps can be used to charge two 48 volt 200 amp hours batteries in parallel. That is a total of 4 200Ah batteries.
This is standard configuration. If the wind is strong and the wind blows 24 hours a day, you can connect one or two groups in series. In this case, the charging current of each group is 41.6 amps divided by 3 groups equals 13.8 amps, or divided by 4 equals To be continued
What do input and output refer to?
Answer:
Output refers to the output power of the wind turbine: Watts, which is W,
Input refers to the input power for charging the battery: VA That is W,
How are the above data calculated?
For example, if a 100W wind turbine is equipped with a 120Ah battery (2 pieces of 60Ah),
can I use one 120Ah battery, or three 40Ah batteries? ?
Answer:
You may not know much about batteries.
You only pay attention to the capacity of the battery,
not to the voltage of the battery. .
The voltage of a single lead-acid battery is 2V,
The voltage of a single lithium battery is 3.6V,
The voltage of a single nickel metal hydride, nickel iron, and nickel cadmium battery The voltage is 1.2V.
For example, a 100W wind turbine is matched with a 120Ah battery (60Ah 2 pieces),
Here,
60Ah predicts that you are referring to a 60Ah*12V lead-acid battery ,
The 60Ah*12V lead-acid battery is composed of six 2V lead-acid batteries connected in series,
then a 60Ah2 block can be composed of:
1. 120Ah*12V lead-acid battery;
2. 60Ah*24V lead-acid battery
I predict it should be point 2, that is, 60Ah*24V lead-acid battery,
And the 120Ah battery you mentioned is wrong!
If you are wrong about the 120Ah battery,
then you cannot use a 120Ah battery,
nor can you use a 40Ah battery. Three batteries!
And if what you said about the 120Ah battery is correct,
then you can use a 120Ah battery, or you can use a 40Ah battery. Three pieces!
The above involves the problem of series and parallel connection of batteries.
Series connection increases the battery voltage but the capacity remains unchanged.
Parallel connection increases the battery capacity but the voltage remains unchanged. .
As far as lead-acid batteries for electric vehicles are concerned, usuallyThere are three types: 24V, 36V and 48V.
After you understand the principles of battery series and parallel connection,
I will answer your question "Who can help me with the calculation process of the above selection"
Calculation and comparison,
For your wrong
"750W wind turbine matched with 240Ah battery (120Ah 3 pieces)"
Modify to:
The 750W wind turbine is matched with 360Ah batteries (120Ah 3 pieces)
And
"The 750W wind turbine is matched with 360Ah batteries (120Ah 3 pieces)"
It may also be wrong. Modify it to:
The 750W wind turbine is matched with 120Ah*36V battery (120Ah 3 pieces).
Other similar errors have also been corrected.
< p>According to the fact that the input is greater than the output, the output is less than the input, the calculation is as follows:Output: less than the input:
100W wind turbine is matched with 60Ah*24V battery (60Ah2 pieces);
100W is less than 24V*12A=288W
200W wind turbine is matched with 60Ah*24V battery (60Ah 2 pieces);
200W is less than 24V*12A=288W
< p>200W wind turbine is matched with 90Ah*24V battery (90Ah2 pieces);200W is less than 24V*18A=432W
300W wind turbine is matched with 120Ah*24V battery (120Ah2 piece) ;
300W is less than 24V*24A=576W
750W wind turbine is matched with 120Ah*36V battery (120Ah 3 pieces);
750W is less than 36V*24A=864W
The 1000W wind turbine is matched with 120Ah*48V batteries (120Ah 4 pieces).
1000W is less than 48V*24A=1152W
Note: The above current is the data obtained by dividing the capacity by 5.
