Dear All, I have been following the many interesting discussions on this list for sometime as I have long planned a EV conversion project. The project has now materialized and I thought it is a good time to reach out to the community to seek some advice. First of all let me give you little bit of back ground:
This project was conceived to promote greener initiatives in the tourism and travel industry in Sri Lanka. We have identified a high impact (environmental and sustainability) market, Safari touring vehicles in national parks of Sri Lanka to adopt sustainable and greener alternatives. We have embarked on building the first prototype, the host vehicle is a TATA pick-up truck with curb weight of 1950 kg and full load weight of 2900 kg. It is a very basic diesel vehicle, it is rear wheel driven. The EV drive train we have identified is from TM4 of CANADA https://www.tm4.com/ <https://www.tm4.com/> we will use the TM4 motor, inverter and vehicle management unit. The motor is TM4 HSM60 (Peak power 90 kW, Continuous 50 kW, Peak torque 270 Nm, con 100 Nm), and C150 HV inverter (Max 150 kW, Max output current 575Arms, max blocked rotor current 650 Adc, performance voltage 320 - 450 V, max electrical frequency 1.25 kHZ). We have conducted simulations using the above system and continue to fine tune these simulations under different driving schedules. For the prototype our bench mark is a range of 100 km (with full load including battery) Charging time of 4 hours (charging system to be determined, we are designing a full solar with storage system and a solar with net metered grid tied system.) The VMU that TM4 sells is priced attractively, however, the basic VMY has to be programmed by factory as needed. The latest VMU can be customer configured but the software is quite expensive ~USD 7200 + USD 12,000 for libraries (not needed but recommended.) I am writing you to ask for advice with the following: Can you suggest a supervisory control systems (VMU) that are easy to to program that we can use with this system? Can you suggest a 30 - 40 kWh battery system that is attractively priced that I can source for this application, battery system is not decided on yet) Can you suggest an on board charger that is also attractively priced but proven (commercially), which can be sourced from US or elsewhere. Any suggestions, helpful tips will be very much appreciated. Anyone interested in involved in a high impact project please contact me privately.
