Hello folks!
Have been hanging here a while, making my reading and looking at some amazing builds.
I bought an e-scooter for 8 months ago and I love this thing more than any other vehicle I owned. Put 2000 km on Odo already and planning to upgrade it to get a better range.
Here is what Ive got:
Chinese JIANGSU XINRI e-scooter, weight 90 kg.
Rider 90 kg, terrain with small slopes
Motor BOSCH 1000W (marked EJ580R60*eM and RBMBLEJ172210004)
TIAN NENG 6DZM20 Lead-Acid batteres 12V20Ah (6 pieces) connected to give 72V20Ah
10 inch wheels with disk brakes
Controller SINE MOTOR for PMSM. Rated 72V, max current 35 A. Protection 63V
DC-DC converter INPUT 48-80V. OUTPUT 12V-10A
- more details are on attached pics
I travel 30-40 km/h with median range of 25 km. I am quite happy with the speed but would like to increase the range to 40-50 km and make the battery pack removable - to charge in the office.
Now onto questions:
My idea is to upgrade the battery to a Lithium pack of 60V 30 Ah with Andersson contacts. Would it be sufficent? The motor is getting 72V now, not sure if the 60V will do. The problem is a huge price gap between 60V and 72V Li packs otherwise I woud get 72V.
Which Kelly controller would be suitable for this? There are plenty on Kelly website and I have no idea which one to chose. Is regen necessary? As I understod it gives 5-10% gain of range. KEB72301x?
I guess I can use the old DC-DC converter.
All help is much appreciated. I will post more as I will upgrade the scooter.
Regards,
Otto
