|This is a concept of a one-way drive that can be modified to enable more than one shaft to drive only one sheave, or gear as the case maybe.|
|The charging system follows this control graph. The reference of the design is based on the "DOE HANDBOOK - PRIMER ON LEAD-ACID STORAGE BATTERIES" found in the link below.|
|This is the charger system of the prototype HEV. The range of the input voltage is 80 to 120 volts AC.|
|This is the voltage and current feedback system. This makes sure that the output voltage and output current are in accordance with the design.|
|This is the control board to interface the computer control software with the rest of the system. It sends control commands to the engine, the inverter, and the charger. It also receives feedback signals that are relevant to the operation of the system.|
All signals going of the computer to the system pass through an optical isolation system. This prevents transients from entering and damaging the computer. Likewise, signals coming from the system are also opto-isolated from the computer.
|The system generates voltage transients all the time. These transients will damage the PC, if it gets there by chance. The design incorporates opto-isolators to provide the required electrical isolation, while providing path for the flow of data.|
The control system monitors many points in the Prototype
