Top speed 60mph @ 6000rpm

Acceleration 0-60mph in 10 seconds

Quarter mile 18 seconds

Motor Control Basic Operation and Safety Features

Motor controller Responds to accelerator. Detects faults in voltage (over/under), current, temperature and throttle signal and shuts down (or reduces performance for low over temps) power to motors

Ignition Relay Provides “key-on” signal to 144v Battery pack

Main Contactor Activated by signal from throttle, connects battery power to motor controller

Reversing contactor Receives signal from FWD/Neutral/REV switch to spin motors in desired direction

Shutdown Relay Disables charger and controller based on faults from the 144v battery pack

Reduced Performance Relay Limits throttle power to Motor Controller to half power when 144v battery capacity is low

Controller Enable Relay Allows Signal from throttle to activate main contactor and controller

Run Disable Relay Eliminates possibility of running the car when the charger is plugged into 110/220vac power

Pre-charge resistor Prevents power surge when the 144 v battery is “awakened” from sleep mode and throttle is engaged

Main Fuse Protects components and wires from over current damage

Battery and Charger

Custom Gauges

Advantages of AC Drive Systems

• Safer: No possibility of Runaway condition with a controller/inverter short; When a DC motor controller shorts, maximum battery power goes to the motors until the battery is disconnected

• Regenerative braking inherent: As the car slows, batteries receive charge. This can be done with DC systems, but it requires more time and extra components to accomplish

• Efficiency: 90-95 percent efficient transferring power from Battery to wheels compared to DC with 65-70 percent efficiency

• Requires less components: Three wires from motor to controller/inverter instead of four / No reversing contactor needed

• Range: 25 percent more range

• Torque: Wider range of Torque/Better Performance

Advantages of DC Drive Systems

• Less Expensive: DC motors range in price from $1000 to $3000 and motor speed controllers range from $1000 to $4000. AC motors generally range from $3000 to $18000 and controllers/inverters range from $4000-$6000**

• Lower Voltages: DC Motors and controllers can operate successfully on less than 200 volts. Most AC drive systems require a minimum of 300 volts to have decent performance**

**The AC drive system on our VW Beetle is an exception; it costs less than $4000 for the motor and controller together and uses 96-108 volts.

Advantages of Lithium Ion

• Improved cycle life: Lasts longer- roughly 100,000 miles

• Higher energy storage: Longer vehicle range per charge

• Lighter: ½ to ¼ the weight

• Smaller sizes: More freedom with installation

• Maintenance free: Many Lead Acid Batteries need to be filled regularly

• Slower Loss of charge when not in use

• Less expensive long term: 4 times the battery life eliminates the time and expense of changing batteries every 12 to 20 thousand miles

• Lithium Cobalt has twice the energy density of Lithium Iron Phosphate

• Lithium Iron Phosphate is safer than Lithium Cobalt: misuse can result in higher risk of fire/explosion

Advantages of Lead Acid

• Less Expensive short term: $2000 to $5000 for Lead Acid Batteries, $10,000 to $20,000 for Lithium Ion Battery pack (with Battery Management System)

• More readily available: Not only are lead acid batteries easier to purchase, their construction does not require the use of a limited resource. Lithium is a rare metal; Half of the worlds known lithium reserve lies in Bolivia, a country not friendly to foreign industry**

• No Battery Management System Needed: Batteries are safer and easier to equalize
