Maybe some more informations on EV and what's about....as Jim showed some important points....and in the other hand, you can't get proper information about EV via media due to the lack of knowledge
some facts
about tire
- as Jim mention right, one of the issues are tires/wheels - especially size and material
- I could talk on Sunday with a specialist about the tire situation here in Germany
- it sounds that some brands in the USA having a restriction in the use
- here in Germany the EV comes with special EV tire, it's on the owner if he stays with that tire or he buy normal one when the original are gone
- all this EV tires having the same base
- tall, with a very low rolling resistance and mostly, narrow....build for lots of miles...the customer like to go 30-40 000 with them
- tall, isn't a issue, as the torque of an EV means with the first move 100 %
- low rolling resistance means special rubber compound !
- narrow reduce also the rolling resistance
- what means that for safety.....tall, hard rubber and narrow tires increase the length of breaking distance.....not very safety.....especially as an EV is much heavier than a old tradition car....and
weight increase the length of breaking distance
- this combination also reduce the safety driving in rain
- in other words, the customer accept the lack of safety, just to get more miles out of the kwh and saving on cost changing the tire not that often.....
- who cry loudest than when this thinking cause a incident....because it was not there fault to save money and safety on the wrong place....
- the load of an EV can't be used as a reason for so tires....as in the USA the SUV's are very the same weight....and they run with regular tires....old traditional cars became heavy in the last
15-20 years and that without E.....
all that blabla from the brands about tires has to have a other reason than EV....may be it is the advertisment....if you drive a EV you can save money on tire....but not telling the lack on safety
something other, the main battery of an EV....means the one for the E motor
- first, safety....there are several reason why a main battery can explode or can get on fire
- if there was an issue during the production of the battery, every charge can cause a reaction
- if an EV has a incident or contact crash, the battery always can cause a reaction
- finally ageing and wrong charging can cause a reaction
- for all the possible reaction...means blow or fire....
- it means not that the battery explode or get on fire when the damage happens....after a incident, a bad charging...it could be up to six weeks that the battery explode or burns...
- that's the reason why an EV (or the battery alone) after a crash has to be in a quarantine box....this is a container full with water....and this for six weeks
currently the industry still has no concept to avoid the reaction of a main battery....as the numbers of possibility why a battery react is BIG.......this has something to do how a so main battery is built
also to view is the emission of a EV, especially here the main battery
- first of all, an EV runs only clean if the electric power which was used to charge the battery is clean....how much percent of clean electric power you got in the USA....in Germany they
saying 40+ percent....which is a lie....from the place where they can produce clean electric power to the place where the power is used, they losing more than 50 percent of that....in other
words...finally 20+ percent....and thinking about clean electric power, it's maybe California which got a high percentage on clean power and also short distance to the user
- the most people are not aware, what it means to produce a main battery for an EV
- talking about size of a main battery....70-100 kwh....which is maybe the today average in an EV....to produce a so main battery....how much emission it creates?
- to produce a main battery in that standard size, the producer creates so much emission that a 180 ci diesel car can drive 100 000 miles.....than the diesel has produced the same amount on
emission....when the diesel goes further he starts to produce more emission
- but this number of 100 000 miles distance counts only if the electric power used to charge the EV comes from a clean electric power producer.....dirty electric power increase the distance....
- how many main batteries will go 100 000 mile (or more).......?
I will not talk about other enviroment destroying in South America and Africa for material which is necessary to produce this main batteries....this would be another long story.....
