You buy if normal manufacturer manufactures electric car, manual and certificate of approval these places, how much is basically can tagging electric machinery power, a little of within an inch of, you are about to see parameter of electric machinery nameplate was judged, after all electric machinery manufacturer and leader plant are departure, electric machinery manufacturer the product to popularize oneself, also meet as far as possible of normalization. If electric machinery does not rely on chart, you can see controller only, be no good really, look for a dc ammeter to measure with respect to oneself carry electric current come for nothing probably estimation, ask attention: Allow aid igniter
Generally speaking, the directest and efficient way looks the nameplate parameter on electric machinery namely, the electric machinery that factory of normal electric machinery leaves factory is built in end left or the meeting on the brim on the right side of is engraved make electric machinery number and label, have the label of **V***w among them, ** is the rated power value that *** of rated voltage value is electric machinery. Have above write XXX48V500W, it is the electric machinery of 500 tile of 48 bend over; On electric machinery if hitting XXX48v350w, be 350 tile of 48 bend over.
So called nameplate, bring a when going up in the crust of electric machinery little sign, can break word of a know exactly about sth and the code that the letter comprises, actually before a few letters are the abbreviation of the brand of electric machinery or type commonly, later immediately afterwards two digit word and a letter, for instance 24V, 36V, 48V, show the rated tension of electric machinery. It is 3 digit word and a letter accordingly again, for instance of and so on of 380W, 420W, 800W, show the rated power of electric machinery. Of course, if join electric machinery manufacturer,be flicker person, so you see these also is no use.
Do not be at ease, can look for avometer to measure storage battery to fill electric time directly, it is voltage of how many bend over probably, measure next one sky to carry electricity next, carry electricity for nothing, having brushed estimation is rated 15% controlled, through carrying electricity for nothing, can turn over cipher out rated electric current, the product of voltage and electric current, consider 9 become efficiency again, can calculate a power to come probably.
