electric car companies engaged in planned obsolescence???

 ELECTRIC CAR COMPANIES ENGAGING IN PLANNED OBSOLESCENCE???

Every major electric car on today's market is equipped with only a
110volt a.c. electrical plug for plugging into house current (the
electric company) in order to charge a BUILT-IN  battery pack.

The companies know that as soon as enough of their cars are sold, and
thousands of them are plugged into the grid at night- this will
overload the grid and cause power outages.(witness summer outages in
California and the east due to airconditioning, hot water, etc
demands)

These outages and the resulting necessity of enlarging the grid
capacity will cause electric rates to rise dramatically!

The result is that more and more electric vehicle (EV) owners will opt
to install their own home photovoltaic systems and/or wind electric
generators to charge their car. This will mean a need for a REMOVABLE
BATTERY PACK- so that one pack can be charged during daylight and/or
windy conditions, while driving the car on the other pack. When the
car returns home, the depleted pack is simply quickly exchanged for
the charged one(with a wheeled dolly, if necessary) . This ability to
quickly exchange packs means that owners will have the charging
capacity at home to maintain a readily available charged battery pack.

 Guess who will be raking in the dollars for making this retrofit!?
Not only the car retrofit, but sales of battery packs, pv panels and
electrical connectors to fit their car!

The car companies can make a removable battery pack NOW!

 If this makes sense to you- send this email to the following EV
companies:

Crap, there is excess capacity at night for charging, and you can
readily recharge from other sources.
Not everyone is going to buy one, and the entry of plugin hybrids and
EV's is going to be a gradual thing,
hardly enough to overtax the grid.

 

     Yes!  What you posted is pure bullshit.

    Significant extra capacity exists on the grid at night, enough to recharge
thousands, if not millions of EVs.  In any case, the adoption of EVs will be
slow enough for the grid to adapt to the extra load.  In the unlikely event that
what you predict eventually does come to pass, the effect will be so gradual
that the first generation of EVs will already have been consigned to the
junkyard.

 Thanks for the opportunity to "ring in" on this matter.

Per Tesla Motors
 http://www.teslamotors.com/efficiency/well_to_wheel.php
their cars are more energy efficient than at least some gasoline,
natural gas, and hybrid cars, but I don't know where a Tesla fits in
terms of electricity use compared to other all electric vehicles.
I will, however, use the Tesla numbers for load calculations.

Per Tesla Motors' page
 http://www.teslamotors.com/efficiency/charging_and_batteries.php  

220 miles per charge
3.5 hours to charge
 [voltage per other sources using 220 volts] 70 amperes.  

Other sources say the total electricity per charge is
53 KWH per 220 miles

Assuming 10000 miles/year (average in US is 15000, but I'll
assume Teslas would be driven less.)

This is about 45 (10000/220) charges per year.

So the load per car is about 160 hours.  There are
about 365*8 low rate hours per year, average night time
load per car is 15KW*(160 hours)/(365*8), which comes
out to less than 1KW.

For USA:
 1000 electric cars = 1 MW  : no big deal in most cities
 1% electric cars (about 1 million in USA) = 1 GW : Probably
    not a big deal load is nationwide.  Might be big deal
    some areas
 10% electric cars (about 10 million in USA) = 10 GW : probably
    need more power plants

NOTES:

 I am not taking into account the cost of making
 or disposing of the batteries.

 Nor am I considering  that many people don't have the space
 or the money for multiple vehicles, which would increase the
 vehicle rate and reduce mileage by perhaps a factor of more than
 two.

The home battery bank can recharge the one in the car. It will be a
lot cheaper if it doesn't have to stand vibration or a crash

Problem solved. Next one?
