Lithium battery capacity unitWhen the capacity unit of the lithium battery is mAh, time, time, WW.
Use compliance: MAH (MAH); safety AH (AH); Watt Wan WH.
The physical meaning of the popular point of battery capacity means that the battery can accommodate or release how much charge, we often use AH (MAH) or MAH (mA).
According to the definition of the current: I = q / t, the MA (mA), T represents when Q = IT, the current I is measured, and the unit HOUR (time), so our battery capacity unit is MAH.
That is to say, if a battery capacity represents 1000 mAh, if he works 100 mA, it is theoretically to supply 10 hours.
However, from the formula we can see Q = IT, and does not involve the voltage, so this unit can only explain how many coulons can be accommodated inside. But you can't explain how much the battery can do, and how much the battery available * is available. Working voltages of different types of products are different. So we have often seen a number in the WH in MAH. Battery can do W = UIT = UIT = UIT = UI, the unit of the voltage U * current I is W (watt), so WH in the battery is represented by WH, which indicates how much the battery can do.
2, Huizhong battery capacity calculation
Battery capacity (c) calculation method: capacity C = discharge battery (constant current) IX discharge time (hour) T reverse: discharge time t = capacity C / discharge current (constant current) i, such as a battery 500mA (mA The constant current is 2 hours, then the capacity of this battery is equal to 500 mA * 2H = 1000mAh = 1ah, and then the current is placed in a battery for 2 hours, then the capacity of the battery is 10ah.
3, battery capacity and power conversion
From the unit to the unit Watt (W), from P = Ui, 1W = 1V.a (a tile equal to a volt-action) battery capacity MA.H (mA time) significantly these two parts are different.
To find a relationship:
Electrical energy power unit Joule (J) by w = Pt: 1.j = 1W.S = 1V.AS (a focus equal to a voltane) If the battery is known, use the voltage by the voltage to take a battery capacity. What did you get: Unit VMAH is actually the same as the unit of electricity, translation:
1v.ma.h = 1V * 10 ^ -3a * 3600S = 3.6V.a.s = 3.6.7

Texas has always been an energy heavy town in the United States. The hurricane also impacts local energy industry. The local refinery has been discontinued, and the closure of water and land transport channels also affects gasoline delivery. Affected by this news, US gasoline prices have risen to the second year, as of the next cut, New York Commodity Exchange Gasoline September futures increased by 5%. According to CNBC, the refining production in Texas is 5.6 million barrels per day, Louisiana is 3.3 million barrels / day, and the hurricane is expected to have caused the production of over 2 million barrels per day. There is also an analysis, and more refinery will be closed in the next few days, which means that the capacity of one in the United States will be affected, and the scale of floods is sufficient to enable production in the next few weeks or even months.
