Camera Battery Maintenance
Now, the camera is on laptop battery power. The use of batteries there are many places where attention should be paid so that the toshiba battery "longevity."
Clean the battery
In order to avoid the loss of electricity, you have to maintain contacts at both ends of the battery and battery lid clean inside. If the surface of dirty words, it is necessary to use soft, clean dry cloth to gently wipe off, must not use detergent solubility, for example, diluents or solvents containing alcoholic content, clean, your camera, batteries or is the charger.
Rechargeable battery
The charging time depends on the charger and battery used, and the use of factors such as voltage stability. Normally used for the first time to the batteries (or used for months without batteries) rechargeable, lithium batteries must be more than 6 hours, Ni-MH battery is more than 14 hours must be that it would be a shorter battery life. When the battery power when there is residual, so as not to repeat the charge to ensure that the battery life.
Battery life
The use of the process to avoid over-discharge situation. Have a discharge that is more than the limits of power consumption. Otherwise, even if the recharge capacity can not be completely restored, is an injury to the battery. As a result of over-discharge would result in battery efficiency, capacity reduction for this video cameras are equipped with battery alarm function. Therefore, in such cases there should be a timely replacement of batteries, as far as possible not to let the battery run out of a video camera automatically shuts down.
Save battery
If you do not use the camera a long time, we must separate from the camera or battery charger inside out, and fully discharged, and then stored in dry, cool environment, but also to avoid the battery with metal objects generally stored in together. In order to avoid short-circuit the toshiba satellite m40 battery, toshiba satellite m45 battery problem, the battery when not in use, the application of protective cover save.
Modern released the second generation fuel cell Tucson SUV
Los Angeles, California, has just opened in Los Angeles auto show, Hyundai Motor Company's Fuel Cell Electric Vehicle Project (FCEV) Group has released its second generation with fuel cell vehicles - Tucson FCEV. This car than its predecessor, the Santa Fe FCEV technically significant progress.
Tucson FCEV's driving mileage than the Santa Fe FCEV has doubled, and further extended to 300 kilometers (about 186 miles), which is mainly due to its with the 152 liters (40 gallons) of hydrogen fuel storage tank, this device is by the Canadian Industrial Dynete developed.
In addition, the Tucson FCEV fuel cell in the current car is only a start in the sub-zero models. Been tested and proved that the car can be for five days in temperatures of -20 degrees Celsius to normal startup. By contrast, with 72 liters of hydrogen fuel storage tank of the Santa Fe FCEV lacks cold weather start in the capacity.
Car than its predecessor a little light, and its maximum power is also higher than the St. 5 kilowatts to 80 kilowatts, the maximum speed of 150 km, and Santa Fe is 124 kilometers.
Its other advanced technologies including a higher output fuel cell and a newly developed lithium-ion polymer battery. Hyundai's general manager in charge of product development KimSang-Kwon said: "this fuel cell vehicle in the technical progress of the whole project is a very good forward step."
Hyundai plans to carry out large-scale three-month test period. Modern in Oakland, California Edison and Southern California, United States Technical Center has a modern, but the activities of these tests will eventually be carried out in other regions. Kim said: "When the project to a new stage, we will test the large-scale production of higher-capacity fuel cell vehicle, which ultimately produced for our commercialization of fuel cell vehicles a solid step forward."
May be "wearing" come out of solar cells
Canadian scientists recently invented a weaving clothing can "wear" the body of the solar cell material. Shirt If you use this material, it can also act as a portable power supply for charging mobile phones and notebook computers.
The inventor of the battery materials, Department of Electronic Engineering, University of Toronto professor Sargent said the batteries can use the sun's infrared light to produce electrical power, and in cloth, paper or other material that constitute a flexible thin film surface . Films can be woven into the shirt or sweater that used to charge mobile phones and other items.
Sargent said that the battery is used in infrared photovoltaic energy conversion technologies, and its solar energy conversion efficiency is 5 times the existing methods. It can be 30% of solar energy into electricity. This toshiba satellite m50 battery, toshiba satellite m55 battery can be used at night. Sargent said: "even if the days seem to be black, there are also a number of infra-red energy."
