Hi all,
Progress on the NHW20, is that it now has 13.5kwh of Lithium Storage, and with 3 converters , 10.5 kw of charge transfer is available.
The aim of this is to reduce the use of the original HV pack , to optimise the EV operation, and not overwork the HV pack.
I have used a Torque scanner program, with a bluetooth OBD 11 adaptor, and can nicely display the HV amps, and evaluate when and how many converters to run, to maximise the effectiveness. The intention is to automate this by observing the current flow in or out of the HV battery, and switching the converters as required.
The present set up, allows for 75km of EV driving, at 70% DoD. This has been an interesting sideline to achieve the main aim, which is to then use the Woodfired 10Kw trailer either towed behind the Prius, or pushing into the firms network, and then extracted for charging at other times.
