< user and request matter > It is anxious that the engine
rotation varies though one million is multiplied and it overhauled it
because overheating is caused and the head bolt broke. Because it might
be an electrical system, I want to strengthen. The car inspection was
just taken at a BMWs special factory named the Ge Co. in the Katsushika
ward town or it is ameliorable as Batterebstar "F130 that is" is put or
I want you to see.

< opinion in state > BMW850i is a playground Zarah sports
model as the flagship of BMWs. 12 Tstscda engine is installed, two
batteries are installed in the power supply, and making to a large
capacity is measured. However, a serious thing came to light. It is
right and left of the trunk, and it is left, emptiness, and the battery
liquid how is ..about 50% in the right.. ..saying.. in the installed
battery though it is a thing of just having finished the car inspection
in September. It was a situation however not amusing though the
hydrogen explosion was caused and the trunk blew off though the
decrease of the number of battery liquids was early because 850
originally needed a considerable electric power. The pat wholesale
goodness or more came to light the shoulder of the staff everyone, and
it was an investigation afterwards, and the thing that the omission car
inspection is obviously done came to light from the description as a
normal liquid level to the car inspection record list of the Ge Co.
because it had been guessed that the explosion might be caused surely
in a few days. (Shinagawa District Land Transport Bureaus Maintenance
Section is investigating this trader. )、This 850 became the favorable
factors to test whether the battery liquid disappeared and where the
battery that had become unavailability recovered in this test report
though were ..keeping of the engine barely the electric power only of
the start for two batteries to...
|
|
The first installation day It
is an omission car inspection and the battery is Paa. a serious
factThough it is likely to have started because there manage to have
been two batteries. However, it ..fear.. explodes ..-.. hydrogen. The
trunk might have blown off.
|
 |
 |
@
Two batteries of the battery and the trunk with problems are installed right and left.
|
A
The battery liquid doesn't come out at all though the detached battery
is grounded and it leant it sideways. These kind of things?It made it
..the staff everyone agape... It made it to Zotsu when thinking that
the trunk exploded hydrogen and blew off a little more.
|
 |
 |
| B It is not possible to measure it at all though the specific gravity
was measured after the replenishment liquid is put in a defective battery.
The float comes to the surface and even 1milli doesn't come to the surface
of the water. It dies completely uselessly. |
C Then, it charged with a rapid charger, and it decided to measure the
specific gravity again the next day. However, the specific gravity ..edge
of 1.1 and the red line.. comes off though the float came to float. 、It
is already useless. This battery can do nothing but be thrown away. |
 |
 |
| D Well, it is a real thing ..here... ..effect of "".. really?、It
is a photograph of the specific gravity that installs "" only
in a left battery and runs really and measured it for about two hours.
Feeling of "It ..terrible.. installs and the specific gravity will
begin to recover in only two hours" everyone. |
E Here hardly recovers still even if running though measured the specific
gravity of a right battery that doesn't install "". |
The specific gravity doesn't return to the use
critical point in the right battery not installed though the specific
gravity greatly went up to the vicinity of the yellow zone in a left battery that installs "" by generating the effect of the float between "" and left battery only by having really run for only two hours. This difference is epoch-making. I will publish an additional report running a little more and crowding. Please ..enjoyment.. wait.
|
|
The second installation day It would run in addition for about one hour by the town ride the next day and it crowded.
|
 |
 |
The second day ran further for about one hour with "F130 that was"
installed and was seen. Then, a left battery of the installation was
measured in the specific gravity again. Very, the specific gravity has
gone up further than yesterday. When
the becoming it battery might be completely restored to Buddha once,
too it is power when it is ..Wo.. -, and this morale to say. Is this
terrible?Everyone was deeply moved again.
|
The photograph where the right battery not installed was measured again is this. Though damage is a battery ..few... ..- however... It doesn't change at all.
|
The third installation day It was finally expected, and a certain thing began to happen.
|
 |
 |
|
That?The left is this time and there is little kooky yesterday. ?
|
A right specific gravity began to go up rapidly reversely.
|
Two batteries have adhered to
BMW850i. "" is an installation on the left side. A right and left
charge difference has grown in an advanced to some degree place though
a left specific gravity went up first. The left: Battery that began to recover + that is. The right: Only a defective battery :. As a result, a right specific gravity began to go up by generating an effect of the float left vs. right, too. It is an effect that "" is excellent that such a phenomenon happens.
|
The fourth installation day The
long distance was boldly driven this time. The round trip in -
Tsuchiura and ten Tokiwa road and Tokyo weeks in the Tokyo Metropolitan
Expressway circumference were done. Prolonging the first time at 3:00PM
and having ended have become 10 PM. The specific gravity finally went
up even to the yellow zone. I think that it can understand so that the
scale may completely risen to the vicinity of the center of the yellow
zone though light reflects to the glass of the gravimeter and the
exposure is exaggerated though it burns and it took a picture of the
flash because it has darkened. The test is started and a finally right and left battery has risen even to the yellow zone evenly during the fourth day.
|
 |
The fifth installation day The battery was detached from the car, and the specific gravity and the voltage were measured once.
|
 |
 |
 |
 |
|
Left battery
|
Right battery
|
Left voltage
|
Right voltage
|
|
Some specific gravities are improving to the side where that was was installed.
|
The right side that revived by being O after the float is done by improving a left battery still somewhat is low.
|
12.57V of both parties of two batteries was shown.
|
|
The specific gravity completely
revived to the region of using regularly. The battery that became
unavailability one degree is a surprise to have been reproduced even at
the level that there is usually no problem in driving at all though it
doesn't reach even the same glee line as a new battery though it is
made to do. In this installation experiment, it is understood to have
succeeded in keeping of the effect of accumulation of electricity of ""
potential, and high improving the battery of low potential that became
Buddha in the effect of the float.
|
The sixth installation day
|
 |
 |
| Well, it is the sixth day of the
experiment finality day. The experiment ends after today because it
will return the owner BMWs tomorrow. It runs 100 kilometers at the end,
"" will be detached, only a single purpose voltage of the battery be
measured at the end, and it see. It improves further a lot of - today.
Left battery 13.27V I think that it might already be right battery
13.05V new battery. The experiment was ended a little more today though
I wanted to do the test repeatedly.
|
Summary of experiment result. It
turned out that the I/O of the installed side went up if "" was
installed in the one side of ? twin battery car, the specific gravity
recovered previously, and the other connected in parallel recovered for
several days because of the delay. Originally, it was proven that the
side where "" had been installed gave priority and the ability went up
because it gave priority to a good point (I/O was early) as shown in
electricity and it flowed though it was sure to recover at the same
time because two batteries were connected in parallel.
|
The effect of the float of "F130 that is" is \ (^^)/terrible. The
charge of a battery that settles down completely also the varying
engine rotation, and is finally right and left and the voltage have
recovered. The face with which the owner is pleased is the enjoyment.
