Re: CCS to CHAdeMo adapter?

I'm going to build a scope and milestone plan for the adaptor, as well as a Bill of Materials (BOM). The Tesla price of $1000 per adaptor may not be very far off of low volume part cost, these are very expensive connectors in low volumes for UL listed versions. Plus the adaptor will need to be large...

Re: 6.6kW effective charging?

Ok, a simple case for doing 6.6/7.2kW charging or quicker is to install a dedicated 'on-board' charger at your home and utilize a communication gateway to translate from the GreenPHY and J1772 standards on the pilot pin to the CAN or analog communication expected by the stand alone charger. In this ...

Re: CCS to CHAdeMo adapter?

These adaptors are mostly about communication and less about the power connection. The two standards are publically available, its possible to make an Arduino based interpreter module and make an adaptor kit. I can look into it, but it will take some time, initially development for reliability and s...

Re: 6.6kW effective charging?

Sticking to the topic of feasibility here and the reasoning behind the 3.3kW choice from an Engineering perspective; There is a general case set of charge rate numbers based on the rate in cell capacities that a battery cell may be designed to operate at safely and reliably in the very long term. A ...

Re: 6.6kW effective charging?

Hybrid and EV Engineer and Spark EV owner here. The same cooling that is used during driving on a hot day or Fast Charging is available during J1772 charging. The limitation is indeed the on board charger itself. Unless specifically designed to operate in parallel an additional charger is not feasib...
