A USB current sensor

Want to know how many amps your motor is pulling? Want to know how much juice you are giving your batteries? Have you ever just wanted to know exactly how much power is going through a particular cable in your electric car? You need a current sensor. Once again, RechargeCar Inc. to the rescue. Our AutoBlock AMP can do all of this and more:

  • measures current flow up to 1000 AMPS
  • able to measure current flow in BOTH DIRECTIONS
  • HIGH ACCURACY - down to less than 1 AMP.
  • samples amperage at up to 60 TIMES PER SECOND.
  • hall effect based sensor is galvonically ISOLATED from the high voltage system
  • DIGITAL communication via USB
  • ANALOG communication via other methods*

    • We have designed the AutoBlock AMP to provide many options for you to communicate with your system. Use a standard USB cable for a digital link, or stay tuned to discover what other options can be found under the "secret hatch."

    Setup and operation:

    The AutoBlock AMP is easy to install and use. The large 1" hole allows many sized wires to pass through. Use the optional cable mount to attach to a cable or simply bolt it or wire-tie to something using the two 1/4" holes.

    The AutoBlock AMP can be used by itself for simple Amperage measurement (or A•h measurement) or in conjunction with our "AutoBlock RPM" to provide even more advanced functionality.

    A basic setup of the AutoBlock AMP is shown here. A large gauge cable passes through the AutoBlock AMP and secured using the optional cable mount. The magnetic field created by electricity flowing through this cable is measured by a Hall-effect sensor inside the AutoBlock AMP. This analog signal is filtered, scaled, calibrated and finally converted to Digital. This digital signal is sent via USB to the computer 60 times a second using our "Open-API packet structure"
