混能車的疑問︰電池壽命

billytao

it may not  save  much money in terms of all cost , but it is the great concept that we are saving the EARTH . that is a BIG thing which every LITTLE human being dream to be able to do

呢Ｄ電池好貴架

還有很多可以改進的空間啊!!!

無論電池壽命長短與否，
混能車的出現，已經為車市帶來革命性的改變，
至少減少了汽油的負擔了。

The number of recharge cycles of 1,500 to 2,000 times for lithium ion battery claimed by the battery manufacturers are only under ideal conditions, namely:

1.  Battery should be cool down before charging;
2.  Batteries should never be allowed to totally drained;
3.  Never use a high power charger for quick charge;
4.  Never over-charge the battery;

If the above conditions are not met, you will face some serious replacement bill for the batteries.

混能车每次刹车都会充电,每当低速度就放电,
在城市里开,一日五十次刹车,同五十次慢速, 都好正常
块电每日 ...

Regenerative brakes are more of a gimmick, my experience is you can only get back around 5% of the energy back.

電池壽命...仍需改善

I am developing a Fluxgate Capacitor ala the one in Back to the Future by Michael J Fox.

其實我成日想換hybrid車但都冇換，就係擔心電池問題

hope that it can totally replace petrol some day!

You don't have to wait, it is here, go buy Tesla electric car.

而家混能車愈來愈受重視,相信壽命方面,日後會增加

可能取回电能的效率是是十分的低
但事实在刹车和减速时是在为电池充电
也是在虚耗电池的寿命呢
又请教 5 % 的能量回收
指的是可省 5 % 油 ?

Not 5% fuel save, it is 5% longer range.

At what price though?  I don't think consumers in general are prepared to pay more money to drive their cars especially modern automobiles are already more fuel efficent and environmental friendly.
Electrical cars may not be as clean as you think, they just pass on the pollution to your local hydro electric plants and the disposal of the batteries still a major environmental issue.

咁两种算法是有一点点唔同
呢意思行多 5 %, 即 原来 10 升油行100 公里, 混能10升行105 公里
即混能100 公里用 9.5238升, 省 4.762%油

我的经验是习惯用大油门, 下下踩行的话, 正如C兄所说混能车也省不了多少,
因为一大油便要用上发动机,而不光是用电马达, 那就跟用原来查不多了

That is why I said it's a gimmick.
I am not a big fan of it because it makes the brake paddle very grippy.

The fuel savings of most hybrid today was due to reduce use of the gasoline engine. Take the Toyota Prius as an example, it has a range of about 15 miles for the electric motor, after that the gas engine will kick in.  If your driving distance is less than 15 miles and you may not need to burn any gas at all.

后生仔要求架车有力,反应快,
根本唔用考虑混能

事後孔明

混能車既起步反應係未慢d呢?
