Hi folks,
As some of you, following my built thread, may know I am designing an inverter for a 3 phase induction motor.
Or at least that was the plan...
Right now the project evolved not to be a motor controller, but the complete vehicle management system.
So how does this relate to real life?
A main ECU controls parameters of the vehicle and, in general manages the whole setup.
Each battery (traction and auxiliary) is equipped with a smart battery monitor that reports, real time remaining capacity and battery status. The main ECU therefore controls the charging status and displays to the user.
The ECU can replace the cluster, if desired. It can calculate trip mileage, total mileage and display warning messages. It is equipped with an RFID style reader to unlock and start the Vehicle.
Brake lights engaged automatically when the vehicle is regenerating
There is provision for solid state controls to engage charger and DC-DC and I am working in a solid state battery contactor. This will allow over-current detection and hopefully save the burden of buying expensive DC fuses.
The inverter is based on a dspic33F operating on closed loop DTC. This works with ACIM motors. It can only work when matched with a valid ECU and Key
Maximum voltage will be 440VDC, to match most industrial equipment rated at this voltage.
Right now I would like to know any desirable features that you guys think, from a user point of view, could be nice to implement and perhaps get some help on bits here and there.
There is currently no individual battery protector/balancer. The battery protector does not check every individual cell, it does, however compare each battery block to find a possible faulty cell.
Any advice or tips greatly welcome.
