This is a 12 cell Battery Management chip with MOSFET driver circuit. Here is a link to the chip made by Linear Technologies - http://www.linear.com/product/LTC6802-1. There is also a AVR micro-controller project for controlling the LTC6802-1 BMS chip. Here is a link to google code site - http://code.google.com/p/avr-drv/.  |
This was posted to youtube by Dale a member of the MNEAA Minnesota Electric Auto Association. It uses the same 3 phase motor as I am using. The controller will be different however. Dale used the Azure Dynamics controller and I will be using an Enova controller. |
I would like an opinion on what type of vehicle I should use for the chassis of the Electric Vehicle. |
Enova configuration software PDS32 running under Wine in MacOS X on an intel i7 processor.  |
I found the connector for connecting the accelerator POT, lights, diagnostics, and gauge outputs for the inverter. This connector is a Metri-Pack 150 series connector made by Delphi. The description of the two parts I need is Connector Assembly 30F and the Delphi part number is 12034398 and 12034400.   |
Glenair makes MIL SPEC connectors used on the ENOVA controller. The connectors are from the Glenair Series ITS MIL-DTL-5015 Type Reverse Bayonet Connectors. Tad from Glenair was very helpful in selecting the appropriate part numbers. I still need to locate the manufacturer of the two 30 pin connectors. Leave a message on my Contact page if you know where I might find a the manufacturer. |
 RS-232 connector and GPIO for things like accelerator pot connection, lights and etc. Another reverse bayonet connector and an unknown rectangular connector. The round connector is available from Glenair. The insert is type 16 S - 1 |
 The 6 pin connector in the middle with 3 large pins is the 240 VAC charge connector. My son is taking the nut off of the ground lug. The post with the black insulator is the 12 VDC output lug. UPDATE: The reverse bayonet is type 20-22 |
 Battery Connector and Voltage sense wires. This is another ITS MIL-DTL-5015 Type Reverse Bayonet Connector like the one used on the motor connector. Update: This connector I was also able to find via Glenair. It is a insert type 32-15 |
This connector is for attaching the 3 phase motor to the inverter. I was able to find this connector. http://www.glenair.com/ makes series ITS MIL-DTL-5015 Type Reverse Bayonet Connectors Shell size 36 pin arrangement 3 UPDATE: I spoke with Tad at Glenair. He helped me select the part number for the motor connector. Part number# ITS3108F36-3PN5  YEONHAB 36-3S  |
The front cover taken off so that I can design a mounting scheme. My son is helping me put it back together. The 3 phase motor doesn't have a C-face mounting flange. I have two choices: 1.) buy a C-Face face plate from azure dynamics 2.) Use a metal plate with shims on each ear of the motor cover. Then make threaded holes to mount the the transmission adapter.   |
This is the cold plate water connector for cooling the inverters, DC-DC converters, and Charger.  |

The round connector is the RS-232 connector. The 2 connectors with 30 pins each are for indicators, accelerator pot, CAN bus, motor quadrature encoder, and etc. These connectors I don't have a pinout for yet.  |
Solectria AC-55 motor. Crayon placed on junction box to illustrate the size of the motor. The AC-55 motor is a 3 phase induction motor.  |

The Enova Inverter uses 3 IGBT modules made by Hitachi Model # MBM600GS6CW. The IGBT modules are rated at 600 volts and 600 Amps.  |
