Uber still has a couple battery cells that look like they might be appropriate
for eVTOL applications, such as the E-one Moli P42A. At this point, the compa
ny starts actual testing. It selects those cells and cycles them over and over
to simulate the load they would experience in working conditions.

There's a bit of chicken-and-egg here, because the company needs to both test
the impact of the repeated charge-and-discharge while also searching for the m
ost effective charging method. Because it wants the best battery, it starts wi
th something pretty robust

Mikolajczak and her team then checked up on the cells every 400 flights worth
of cycles. If the company wants to fly 10 or 12 missions per day, it isn't pra
ctical to replace the battery pack every few months, as some were found to req
uire. But, the testing showed that staying within the charging sweet spot prov
ided "substantially better performance," and some tested batteries could last
a full year.

Uber has more testing to do. It can refine its next tests further with the dat
a it's now getting — both from this first round of testing and from its manuf
acturing partners on what their vehicles will require — to continue to probe
the limits of the batteries, check additional flight cycles under different co
nditions and see how they perform in case of failures.



3.心得/評論：
（1）大意是Uber air找上中橡（2104）底下能元科技電池P42A，而且測試結果非常不錯
，能夠確保耐操一年以上不會壞。只是還有其他回合測試需要進行，以確保Uber air計畫
能完美

（2）關於P42A跟新一代P45A的資訊好少，這篇文章是好不容易找到，其他只有在法說會
看到P45A動力及能量能贏日韓。只是先前暫緩擴廠我猜應該是P45A技術出現瓶頸。能元科
技
合併並增資我猜是就是為了接下來擴廠動作

（3）除權前買的2104今天還原解套，耶！
