In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles. [2] [3] In general, number of cycles for a rechargeable battery (the cycle life) indicates how many times it can undergo the process of complete charging ...
People's research on DCFC with GDC-Li/Na 2 CO 3 as the electrolyte, Sm 0.5 Sr 0.5 CoO 3 as cathode shows good performance. The highest power density of 48 mW*cm −2 can be reached at 500 °C with O 2 and CO 2 as oxidant and the whole system is stable within the temperature range of 500 °C to 600 °C.
98.6 °F (37.0 °C) is not the normal or average temperature of the human body. That figure comes from an 1860 study, [297] but modern research shows that the average internal temperature is 36.4 °C (97.5 °F), with small fluctuations. [298] [299] [300] The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ...
This, in turn, results in relatively poor energy density (about 3 kJ/cm 3), rapid burn times, and spray of molten iron due to the expansion of trapped air. Thermite can be pressed to densities as high as 4.9 g/cm 3 (almost 16 kJ/cm 3 ) with slow burning speeds (about 1 cm/s).

Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
2 H 2 O → 2 H 2 + O 2 This scheme is the simplest form of artificial photosynthesis conceptually, but has not been demonstrated in any practicable way. Light-driven carbon dioxide reduction, the conversion water, carbon dioxide into carbon monoxide or organic compounds and oxygen. In the conceptually simplest manifestation, this process gives ...
