I am currently building a TWIZY solar car. Is it okay to power it from 16V to 60

I am currently building a TWIZY solar car. I am planning to install a 200W solar panel and charge a 1Kwh 16V battery. Next, I am thinking of using a boost converter to charge the TWIZY traction battery from 16V to 60V.
Will an error occur if I try to charge a Renault TWIZY using a boost converter with the key on?

• You definitely have to communicate with the Twizy and cut off charging once the BMS tells you to stop (using Battery Charge % and Authorized Regen Power). Maybe Delvecchio can help with his CAN-BUS charger adapter
• The low charging current could be problematic due to Standby losses of the Electronics and Contactors, which I think is 50-100W, and bad resolution of the Current sensor for the Coulomb-Conting, which can result in vast errors in the calculated Battery Charge percentage

Some people here using the "Backdoor" charging way from the SEVCON contacts for aditional chargers, mainly high-curent, quite like the recuperation of the original System, but you have to trigger the main relais in the Battery. No clue if this also works with low-curent charging via 16to-whatever-Voltage.. the User delvecchio is imho _the_ Guy to ask..

Btw., the Pic is great! Like "there is always a place for one more Panel!" And the fixing of the Twizy-panel looks awesome! You would cause the death-by-heart attack of every TüV-Engineer in Germany..
