I think this "Another method of heating an Ev" - story below was interesting, but I did not understand it first, as I was reading it to fast. But not even so after second slow reading could I make it trough this message. No offence, It is not bad, Its just me.
The SHORT: Sugestion: -Again, no offense all people of other small unknown cultures, ..but some Irony might have been added. :-) As this is an international list, please can we try to use the normal units that we all(almost) have used now for 100+ years) And many have used them since year year 1795 just to to clean up the international bad-unit-mess that we had way back then over 100-200 years ago. Please try hard and your very best now and not fall back to the older, harder and highly local unknown ones and/or other bad habits. Of Course We can also continue to cripplecode some messages, but I dont think you will like for example all our older local Swedish units. :-) Let The LONG unit rant begin: (for a deeper understanding of the problem, ..or not.. :-) F = it seems not linear. Please use Celsius or kelvin ? BTU = use Watt and Hours(?) USATU = Watt and Hours HP = please we must KILL all the indicated, british or braked or the invented electrical Horses.. For example: lets measure the A/C equipments cooling capacity in parts of a highly unknown animal. Really?? Cant be the very best method, or is it? R-factor = I dont know about this, but I assume it IS international for insulation calculations? Local here it was "K-value", but nowdays I think it is "U-value".. :-) 300 W of cu bi heating of unknown or generic gas(probably not the Super-"gas" they have in gas stations) = ? complicated! 4 wire = ? Maybe an easy calculation, but I dont know it. But what about MILES? mile = Hmm, Is it English, brittish or imperium (is it the same imperialistic mile?), or is it the local states in 1 other countrys roads, or maybe texas-land area-mile, or international nautical miles or ..is it just a normal(NEW) Swedish mil? :-) Who knows, Ok, But how LONG is this "international" mile? = 1852 I guess! As it seems to be the only commonly used mile nowdays, -Cool! So Can we use this? Well, yes we can! ..BUT this sometimes seems to be mixed up with The Imperialistic (UK) nautical mile someone might refer to...., That is exactly 6,080 international feets = 1853,184 m but abandoned in 1970, so all older references are now converted to 1 85_3_,000 meters exactly here.. The USA-mile was 1853,248 metres here before. (6,080.20 U.S.A feets, based on the definition of the foots recently in 1893. it was also abandoned. and their feet grows bigger when they get richer and can buy more food) English usage of sea mile varies from about 1,855.3 metres to to about 1,849.1 metres I beleve, So you must know exactly where you are at the moment (?), to know how long you have traveled. But in "average" you are close to almost correct if you use 1,85_2_.3 metres average, but you will probably hit the ground hard sometimes.. -Ok, puh.. Is it really that HARD for us to agree to keep one mile distance? Yes, and then there is the geographical "mile"... It is the length of one minute of longitude along the Equator, about 1,85_5_.4 m (on the International (1924) Spheroid )or about 1,855.325 m on the WGS 84 ellipsoid. (Bowditch defines it as 6,087.08 feet, which is 1,855.34 metres. But it looks close to the English seamile? -Yes, in some places, sometimes..) AND PLEASE Do not confuse this with the similar-sounding unit the geografische Meile, in German measurements. The length of FOUR minutes of arc along the equator, standardized as 7,421.6 metres. In the USA nowdays a "Metric Mile" is exactly 1600 long. (?) But all other countries just ignore them, as it is known to be 1500. In Germany, the Mile , Uhr or Stunde typically refers to 24,000 local feet = the distance one might walk in an hour (Stunde) if he likes to do that.And sadly there is also the tactical "mile" or data "mile" used by some navies = 6,000 of local(?)feets of somewhere, but known to be (1,828.8 m) . In the Royal Navy, this is also known as a data mile.- SO.. seems a bit complicated with this "mile"-thing ! Therefore I suggest that WE ALL now agree to use the Swedish "Mil" instead! It is the perfect Mile!! Also I am most used to this one, so I assume that all of you must agree on this, it is clearly the future of units. ""The traditional Swedish mil spanned the range from 6000–14,485 metres, depending on province you had to visit. It was however standardized in 1649 to 36,000 Swedish feet.. or 10.687 km. The Norwegian mil was 11.298 kilometres. When the metric system was introduced in the Norwegian-Swedish union in 1889, it standardized the mil to exactly 10 kilometres. Mil is still commonly used when measuring fuel consumption in vehicles; e.g., 0.5 litre per mil."" And there is *a LOT* of other "miles" out there, for example the Roman imperium mile, or 20+ (?) other ones here: http://en.wikipedia.org/wiki/Mile I beleve Finland have also had at least 3-4 different "mile", depending on who invades their country for the moment, maybe some mil from .se, and some of the .ru miles and also the local Finnland-mile, -Jukka, is this correct? wow.. Here is some other local units, that might ,or not, have been used here on the list: " 1/231 us-inch of 100 Gauges of copper wire" = how many mm^2 is that? How many Swedish "verktum"-inch will it be compared to us-inch? square fots of unknown size per punds of usa-inches = ? Gallons in a mile of electricity, "eGallon" (of unknown local usa-sizes?) = ? How many kWh / 100km is that? Or how many kWh / Swedish mile ? :-) gallon per mile (uk) = ?? Psi(PascalPer..local inches in nice squares) = unknown sized inch ? 100000 Pascal =1Bar , or use maybe inexact but close enough: kg/cm2, or Atm that is more easy to relate to. quarterpoundr (Kilogram) per usafoot (meter) = N m ? mile of roads (usa)=1.6xxx km mile of maps or land(United states) =1.xxxxx km mile (United kingdoms) = 1.xxxxxx km ? mil (United Sweeds) = 10 km mm 0.001 meter meter = 1 meter km =1000 meter ton =1000 kg kg = 1000 gram -But what is 1 lb / sqft = ? Its easy: " libra or libbra (lb)a traditional unit of weight in Italian, Spanish, and Portuguese speaking countries. The libra was the Roman unit from which the English pound is descended; the symbol "lb" for the pound comes from this unit. The Roman libra contained only 12 unciae (ounces) and was about 0.722 English pound. The traditional Italian libbra was often of similar size, but a wide variety of libbras were used in Italian markets over the centuries. The Spanish and Portuguese units are larger, generally in the range from 1.011 to 1.016 English pound (very close to 460 grams). The Spanish libra equals 16 onzas, and the Portuguese libra equals 16 onças. The word "libra" is sometimes used now for the kilogram, a much larger unit." No, of course it is just the Swedish "lb" beeing used here: = SkeppsPund "ShipPound" = 1 skeppund = 20 lispund , as well known that 1 lis pund = 20 skålpund and if you know that 1 <lb> = 1 skålpund will be = 32 "lod", ..as 1 lod = 4 kvintin (or "quarts"?). Now it is very easy to just do the math, as we all know 1 kvintin was ~= 10^-2.47874 kg Then we just have to devide that by 1/6 (maybe) of the email-senders countrys average humans height at some agreed year. (we are toold in school that sometimes in some foreign old cultures feets (foot) is 1/6 of the lenght(height) of their older humans(but they are all dead now, so we cant really measure that) ) and then we put them all in 90 degrees and multiply them? ..Or someting like that, I cant really describe it but seriously we all know exactly what we mean, so I assume we can finally all agree on THIS one, at least? ..right? Great! -Now I only need to find my new EU-banned 60 Newtonmeter per second of metric light-bulbs for my kitchen, so I can see what I make for dinner.. / John ---------------------------------------- > From: e...@msn.com > To: ev@lists.evdl.org > Date: Fri, 11 Oct 2013 09:31:58 -0600 > Subject: [EVDL] Another method of heating a EV > > Receiving my first EV call Transformer I which was a converted 75 Chevelle, > The company, Electric Fuel Propulsion added some additional heating systems > for my car which was to driven in Montana and steep hills. > > The power to drive the heating system or the A/C system does not come from > the main battery pack which was 90 cells lead cells rated at 2.2 volts 180 > volt battery pack.
