How are solar cells and batteries similar in function?
Solar cells and batteries are similar in that they both produce electricity.
What is the total voltage if a 12v battery 6v battery and 2.5v battery are connected in parallel?
There is no answer to this question. It could be anywhere between 2.5V and 12V. If you connected them in series the answer would be 20.5V, in parallel the higher voltage battery will discharge into the lower rated cells, the resultant voltage is dependent upon the internal resistance of each of the batteries. In practice you wouldn't do this, so it's either a mistake or trick question. www.powerinspired.co.uk
What sources of power are used to make a robot work?
photo Voltaic CellsPhoto Voltaic Cells or solar cells are well known for their use as power sources for satellites, environmentalist green energy campaigns and pocket calculators. In robotics solar cells are used mainly in BEAM robots. Commonly these consist of a solar cell which charges a capacitor and a small circuit which allows the capacitor to be charged up to a set voltage level and then be discharged through the motor(s) making it move. For a larger robot solar cells can be used to charge its batteries. Such robots have to be designed around energy efficiency as they have little energy to spare.BatteriesBatteries are an essential component of the majority of robot designs. Many types of batteries can be used. Batteries can be grouped by whether or not they are rechargeable. Batteries that are not rechargeable usually deliver more power for their size, and are thus desirable for certain applications. Various types of alkaline and lithium batteries can be used. Alkaline batteries are much cheaper and sufficient for most uses, but lithium batteries offer better performance and a longer shelf life.Common rechargeable batteries include lead acid, nickel-cadmium (Ni Cd)and the newer nickel metal-hydride (Ni-MH). Ni Cd & Ni-MH batteries come in common sizes such as AA, but deliver a smaller voltage than alkaline batteries (1.2V instead of 1.5V). They also can be found in battery packs with specialized power connectors. These are commonly called race packs and are used in the more expensive RC race cars. They will last for some time if used properly. Ni-MH batteries are currently more expensive than Ni Cd, but are less affected by memory effect.Lead acid batteries are relatively cheap and carry quite a lot of power, although they are quite heavy and can be damaged when they are discharged below a certain voltage. These batteries are commonly used as backup power supply in alarm systems and UPS.BatteriesBatteries are an essential component of the majority of robot designs. Many types of batteries can be used.

How many 100amp hour batteries do you need to connect to a 240v inverter to produce the same output as a 5kva generator for a period of 2 hours?
I am assuming that your batteries are 12V, also that your (12V - 240V) inverter is rated for 5KW output and it is about 95% efficient. Most big inverters are between 85% - 97%. 5KW from a 12V battery would mean a current draw of about 416A, but since the inverter is only 95% efficient the actual current would be closer to 438A. If you draw 438A for two hours, that's 876AH. Theoretically then, you would need 9 100AH batteries. The problem is that at very high current draw, all batteries AH capacity is less than the rating. You only get the whole 100AH if the current draw is 10A (1/10th the AH rating) or less. Because of that, you would probably need 10 to 12 batteries. If you used 10 batteries, each would source about 44A during full load. You would have to use very large bus bars to equalize the current draw from battery to battery. If the interconnects are too small, the batteries closer to the inverter would be forced to supply more than their equal share of the total current draw, and the ones further away less. It's generally problematic to parallel large numbers of batteries in this way. Don't even consider it unless the batteries are identical (same manufacturer, same part number, same age, same date code). The problem gets even worse when you try to recharge the pack. Suppose you pump 50A of charging current into 10 batteries. Is each battery receiving 5A? Or is one battery with a shorted cell drawing all 50 (and is about to explode...)? There's no way to tell. Even if all batteries were receiving equal charge, it would take your 50A charger almost 40 hours to recharge 10 - 100AH batteries. Ouch. Large industrial UPS systems get around this by using huge 2V cells in series. You can buy 6 - 2V, 1000AH cells, connect them in series to form a 12V, 1000AH battery and avoid all the hassles of parallelling 12V, 100AH batteries. They are not cheap, though. If you go to a battery manufacturer's website, they publish graphs for their batteries that show AH derating versus current draw. All this assumes, of course, that your load is really 5KW. If you are running a smaller load, then obviously your battery count would go down. Finally, we are talking extremely large current and power levels here. If you are not fully qualified to understand and design high current wiring systems, don't try this! 400A of current through a bad connection can do serious damage! Unless you enjoy being sprayed with molten metal from a disintegrating connection, know what you're doing or get a qualified individual to help with/inspect your work. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any workANDalways use an electricians test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
