Portable battery power station can be expanded in a wide range of fields, not only in the home, but also in many fields such as office, enterprise, film crew, photography, travel, fire protection, medical treatment, emergency rescue, and housing. Consumer groups and domains. So do you know the common knowledge of portable battery power station? Next, let the editor tell you about the common knowledge and learn it.
How to judge whether the portable battery power station can be used by the device?
First understand the voltage/power parameters of the electrical equipment
Power (P): A term in physics, the work done by a current in a unit time is called electric power. It is a physical quantity used to express the speed of power consumption, represented by P, and its unit is Watt (Watt), referred to as "Watt", and its symbol is W.
For the portable battery power station, the power means the ability of the portable battery power station to drive the load electrical appliances, the greater the output power, the stronger the load capacity.
For electrical appliances, it indicates the speed at which electrical appliances consume electric energy. The higher the power, the faster the consumption of electricity, and the more electricity is consumed.
Compare the power consumption of the load electrical appliances with the output power of the portable battery power station
Before using the portable battery power station, carefully check that the power consumption of electrical equipment must not exceed the rated output power of the portable battery power station, and start the peak power for a short time (mainly used for inductive loads, such as refrigerators/motors/air pumps/electric drills, etc.)
Device Power Deviation
Rated power: It is set when the equipment is designed and manufactured. The rated power means that the equipment can guarantee the power of normal operation, and the equipment can run normally and smoothly under this power. The signs on the electrical appliances are all rated power.
Actual power: The power consumed by the device when it is actually working. The actual power may be greater or less than the rated power.
Note: The actual power and the rated power allow a deviation of 10%, so when choosing a portable battery power station, there must be a margin in the power, otherwise there will be problems that exceed the power supply and cannot be used.
DC and AC
Direct current: Direct current (DC for short), also known as "constant current", constant current is a kind of direct current, which is a direct current with constant size and direction. For example, the battery pack of our portable battery power station is provided direct current.
Alternating current: refers to the current whose direction changes periodically with time, and the average current in one cycle is zero. Unlike direct current, which changes direction over time, direct current does not change periodically.
The waveform of alternating current cannot be directly observed by our eyes, and needs to be observed with the help of a professional test instrument (oscilloscope).
Calculation of the usage time of portable battery power station
Comprehensive laboratory test data and actual use experience, the conversion efficiency of energy storage power supply is about 74% (conservative data)
Calculation of time.
Use time = discharge power ÷ power consumption of load equipment
Portable battery power station1000S usage time calculation:
Example: How long can a 1.220V/60W electric soldering iron be used?
1000×74%÷(60+5)=11.4 hours
2. How long can the 220V/100W lighting be used?
1000×74%÷(100+5)=7 hours
