Re: Hack DC charging - limit to 30kW

And I will repeat stress test many times (between 50 and 100). After that i will make again cappacity test. If w...

Re: Hack DC charging - limit to 30kW

Yes, high drain cell is way. But I find Molicel 2000mAh. If I will use 25pcs cappacity will be 50Ah. No range upgrade. No sense try replace LEV to another cells. Molicel have 6A charge current. 6x25 = 150A. Nice for imiev. https://nexun.pl/pl/p/Molicel-IHR18650C-2050mAh/592 Is Molicel with higer cap...

Re: Just posted my 2017 iMiEV Review to Youtube

Problem is that Mitsubishi sleep.
BMW i3 60Ah->96Ah->120Ah. Mitsubishi 50Ah->50Ah, no progress here.

While imiev is good car, I dont need more. But in year 2019 is 100km range too bad. imiev with 200km range would be a pretty nice car.

Re: Hack DC charging - limit to 30kW

In my head is solution. Replace battery LEV50 to 18650 cells (25pcs). But here is limit to charing current about 80A (30kW). In my country is only 50kW chademo. This is too much for battery from 18650 cells. If I will use this charging method, battery will be quick degradation. I mean. Somewhere in ...

Re: 12V consumption and range increase

300W 12V DC means. 0.3kWh per hour.

If you disable DC DC charger. After one hour driving you will save 3km range :)
