INTRODUCTION TO EVSE TEST SYSTEMS
State-of-the-Art Test Equipment for Regulatory Compliance Verification
With the approval of the new HB44 regulations by the National Conference of Weights and Measures the EVSE market is poised for a major paradigm shift. Until now public chargers have been unable to charge for energy delivered. EVSE’s had to be free, part of some “club” membership, or part of a “parking fee”. This was due to regulations restricting the sale of electric energy to public utilities. With the new regulation EVSE’s will be required to sell energy much like a gas pump sells gas. They must display the price per KWH, show the amount of energy delivered and the total amount of the sale. Like gas pumps these vehicle fueling stations will be under the regulation of state departments of weights and measure. They will have to be tested and sealed, just like a gas pump.
With the approval of HB44 deployment of next generation rapid charging stations is expected to expand dramatically. These new EVSEs allow charging a vehicle in minutes rather than hours. The average range of electric vehicles is forecast to increase from 40 miles to over 200 miles per charge over the next few years. At the same time the cost of batteries is expected to drop significantly due to technological advances and efforts like the Tesla “GigaFactory”. The number of public charging stations is expected to exceed 1,000,000 over the next few years. This creates a tremendous need for equipment to serve this market.
