Nu er der noget nyt på banen, men prisen er stadig ret høj for lithium-ion
batterier.
Fik netop denne reklamemail fra Wunderlich, som er et seriøst firma der
sælger mange ting til BMW:
Lithium-Ion Batteries
Today, lithium-ion batteries are the cutting edge in the evolution of
the vehicle-battery sector. Especially for the motorbike, these batteries
offer a whole host of benefits. Thanks to the lithium technology, which has
already been used for a long time in a similar form in mobile phones, it is
possible to do away with lead and acid altogether. This means that lithium
ion batteries weigh only one third as much as traditional lead-acid
batteries. They are also not only smaller, but can be fitted in any
location, since they do not contain acid.
Lithium-ion batteries will not only tolerate fast charging with
particularly high charging currents (up to 90% in six minutes), but also
hold their charge for a very long time. Self-discharge is a maximum of five
percent a month. The relatively high purchase price of these batteries
therefore pays dividends in the longer term. With six times the number of
possible charging cycles compared to simple lead-acid batteries, the hi
gh-tech JMT batteries have an extremely long service life. In addition, a
built-in processor (a so-called "balancer") ensures that all cells have a
uniform state of charge. Thanks to adapters, our lithium-ion batteries
correspond exactly to the dimensions of the original batteries. The
connections are also identical, meaning the batteries can be swapped in a
matter of minutes.
The facts:
a.. Approx. 1/3 of the weight of comparable lead-acid batteries
b.. Can be fitted in any location, since they contain no acid
c.. Contain no heavy metals
d.. Uniform state of charge for all cells thanks to balancer
e.. Trouble-free quick charging
f.. Low self-discharging
g.. Up to six times the service life of a lead-acid battery
h.. Fast, easy substitution
i.. No memory effect

Det er første gang jeg ser Li-ion markedsført til andet end mobiltelefoner
og bærbare pc.
Hvis levetiden er > 20 år er det jo interessant nok, prisen til trods. Og at
vægten er reduceret til 1/3 er jo heller ikke uinteressant.
Jeg har absolut ingen erfaringer, men vil overveje det, når min akku på
F800en lægger sig til at dø. Den er født i 2008.
