Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 • USA Application Guide: C30 and C60 Hybrid Electric Vehicle (HEV) Application Information for Capstone Communication Requirements The HEV version of the MicroTurbine system requires the user to give commands to the system for starting, power levels and stopping. The communication to the system is done through an RS-232 serial port using RS-232 protocol. Each system has two serial ports. The first is reserved for the user (vehicle operation and the second is used for monitoring and/or maintenance. For basic operation, the user needs to connect a computer or PLC using a null modem adapter or a modem to one of the ports. The user serial port requires a password for control operations. Without a password, information and data is available for monitoring only. For the simplest operation, two commands are used. The RS-232 command STRCMD is used to start and stop the MicroTurbine and PWRDMD is used to tell the MicroTurbine how much power output is desired. The command STRCMD = 1 is used to start the MicroTurbine, STRCMD = 0 shuts down the MicroTurbine, and PWRDMD = is used to set the desired output power level. Additionally, each RS-232 command may be issued without an argument to query the current value being used by the MicroTurbine. For example, STRCMD issued without the equal sign and value will return a 0 or 1 indicating that the MicroTurbine is currently running, or in a shutdown state. This is useful for monitoring the overall system operation. When the battery management system is monitoring the battery state of charge, and it determines that it is getting low enough that it wants the MicroTurbine to start charging, a start command (STRCMD =1) should be issued. A few minutes should be allowed for the MicroTurbine to warm-up, and get to the point where it is capable of outputting power when this is issued (for example, do not start the MicroTurbine with the state of charge too low as it will take the MicroTurbine a few minutes before charging begins). A desired power demand may immediately be issued, and when the warm-up cycle is completed, the MicroTurbine will immediately ramp up to the desired output power level. A power demand (PWRDMD) between 0 and 60000 watts may be commanded. Most likely, once the battery management system sends a start command, the MicroTurbine will be kept on with varying power levels until the bus is shut off at which time a STRCMD = 0 will be issued to shutdown the MicroTurbine. It is much more efficient to leave the MicroTurbine on, and the power output limited then to turn the MicroTurbine off and then start it again. The MicroTurbine remains in a Standby state after power up, until a STRCMD = 1 command is received. It will then transition to a PREP_START state where it determines if the contactor can be closed and the proper power board voltage is achieved for operation. 480009-001 Rev B (October 2004) Page 42 of 54 This information is proprietary to Capstone Turbine Corporation.
