Gridtest Systems Secures Investment from Pasadena Angels and Tech Coast Angels
Los Angeles, CA (PRWEB) March 20, 2012
Gridtest Systems Inc., an independent provider of high-value test and measurement tools for electric vehicle (EV) charging, announced it has closed a seed investment round with Pasadena Angels and Tech Coast Angels. This initial round of external investment enables Gridtest Systems to accelerate the launch of its first product, the EV Emulator EVE-100L, which solves critical test and measurement problems for R&D labs of major charging system manufacturers and product suppliers.
?We?re delighted to close this funding round, which crucially allows us to target all our priority markets with a key product that our customers and prospects have been telling us is urgently needed,? said Neal Roche, CEO and founder of Gridtest Systems. ?We?re pleased that angel investors have recognized our achievements to date and our commitment to becoming a leading player in the electric vehicle infrastructure testing market.?
Pasadena Angels and Tech Coast Angels invested in Gridtest Systems after it demonstrated market traction with key customers in Europe, North America and Asia-Pacific.
?Gridtest Systems is a critically important player in the development of the electric vehicle charging market. The company has a strong and experienced management team, innovative technology, and a clear marketing strategy. We look forward to partnering with Gridtest in its drive to meet the needs of its leading-edge customers,? said Ian McGregor, Pasadena Angels board member.
?Gridtest is a perfect example of the type of Los Angeles-based startup we are looking to invest in,? said DC Palter of Tech Coast Angels. ?In addition to capital, we will provide Gridtest with our collective resources and experience to help them bring their products to market and make them a leader as the clean-technology industry continues to mature.?
The nascent electric vehicle market requires a dependable charging infrastructure
The fast-growing EV Charging industry faces challenges that require advanced test tools. Pike Research forecasts that EV Charger annual sales will reach $ 4.3 billion by 2017. Already, a variety of companies are supplying electric vehicle charging stations (known as EVSEs) to utility companies, EV service providers, and automotive companies. These entities need to ensure compatibility between charging stations and the new generation of plug-in electric vehicles (PEVs) that are entering the marketplace. Recently, General Motors presented a list of compatibility problems that can prevent electric vehicles from charging, highlighting the need for detailed testing of the compliance of charging stations to the EVSE standard SAE J1772?. For successful market adoption of electric vehicles, consumers must be assured of a safe and reliable charging experience every time they plug in their vehicle.
Gridtest Systems? technology addresses an urgent need along the EV value chain
The EVE-100L is the most advanced, independent EVSE test instrument available today. It can run automated tests and report on the functional compatibility of electric vehicle charging stations, enabling the R&D labs of the major manufacturers of charging stations and independent test laboratories to quickly verify the correct functioning of charging stations. Until now, EVSE suppliers factored weeks or even months to comprehensively test a new charging station; the EVE 100L product reduces this by a factor of ten, accelerating their time to market.
The EVE-100L goes beyond simple EV simulator tools by analyzing key parameters that cause compatibility problems with electric vehicles, such as charger state transition timing or false ground-fault trips. The EVE-100L also verifies that the charger can support the maximum advertised current to emulate realistic electric vehicle loads. It records highly accurate measurements and generates comprehensive test reports that aid additional analysis.
In the second half of 2011, Gridtest Systems announced the EVE-100J, a field-test version of its EV Emulator tool, which is used by EV service providers and electrical contractors for installation testing and preventative maintenance on EV charging stations.
The EV Emulator can test charging stations worldwide that conform to SAE-J1772?, IEC 61851-1 and IEC 62196-2 Type 2 Mode 3, vehicle inlets.
*EVSE stands for Electric Vehicle Supply Equipment which is the industry designation for Level 1 and 2 Charging stations. SAE J1772? is a trademark owned by the Society of Automotive Engineers.

What could be the source of a stray voltage on a switch-controlled outlet when it is turned off?
Question by : What could be the source of a stray voltage on a switch-controlled outlet when it is turned off?
There is a switch-controlled outlet in the living room. It works fine when the switch is on, but when it’s off, it reads 46 volts across the hot/neutral when a load (my receptacle tester) is connected. It reads zero when nothing is plugged in. What would cause this?
When I plug in the receptacle tester, there is a very faint glow on both of the amber lights when the switch is turned off (the two that glow when the outlet is wired correctly).
Also, with nothing plugged in at all, the non-contact voltage tester will beep whether the switch is on or off. 46 volts is enough to trigger the voltage sensor tool.
Best answer:
Answer by HyperDog
I’m going to guess that your receptacle tester doesn’t really load down the circuit; that is, it is a high-impedance AC voltmeter and it’s picking up a very small current via capacitive coupling between the wires in that circuit and one or more others that run parallel to it for some distance.
This is a common phenomenon and if you have a very high value resistor, say something upwards of 100,000 ohms, and you place that across the meter probes, you should see the voltage go down to nearly zero.

NEMI Premieres Latest Roadmap at APEX 2003
The National Electronics Manufacturing Initiative (PRWEB) February 7, 2003 -
HERNDON, Va. February 4, 2003 led consortium focused on strengthening the North American supply chain, will premiere its 2002 roadmap at IPC SMEMA Councils APEX conference in Anaheim, Calif. (March 31-April 2). Other NEMI forums at the conference include a review of results from the recently completed Test Strategy Project, and a discussion of how IPC standards are helping OEMs and EMS providers span the virtual factory.
Jim McElroy, president and CEO of NEMI, will discuss highlights of the 2002 NEMI roadmap at the IPC Committee Luncheon on Wednesday, April 2. This roadmap, the fifth one developed by NEMI, features 23 chapters that cover 18 technology, infrastructure and business practice areas and five product sectors: (1) consumer, (2) portable, (3) office systems, (4) large business systems and (5) automotive & aerospace/defense. New in this roadmap are a chapter on connectors, and a single chapter, entitled Product Lifecycle Information Management, which combines the factory information systems, supply chain management and information technology chapters. As in previous years, the roadmap addresses the shifts in each of the technology, infrastructure and business practice areas discussed, along with the related technology gaps and business needs.
NEMIs 2002 roadmap was completed in late December and will be available on CD-ROM to non-members beginning March 31. Orders can be placed through the NEMI website (http://www.nemi.org; $ 250 for non-members) or at the NEMI booth at APEX (#452, Hall E).
Also at APEX, NEMIs Test Strategy Project will present selected results of a year-long investigation of new strategies for testing high-density printed circuit boards (PCBs). The project team reviewed AOI (automated optical inspection) and AXI (automated x-ray inspection) methods combined with in-circuit test (ICT), using experimental testing to measure the performance of these various methods in the manufacturing environment. The APEX forum will present results for three areas studied: (1) defect detection capabilities of combined ICT and AXI test strategies in reduced access environments when both 2D and 3D AXI systems are used; (2) data showing the capability of AOI and AXI machines to discriminate subtle differences in the quality of solder joints; and (3) a test strategy cost model that can be used to estimate the cost, benefit, fault coverage and yield of test strategies.
The Test Strategy Project session is featured as an APEX free forum (F07B) and is scheduled for Tuesday, April 1, 3:15 to 5:15 p.m..
Finally, Spanning the Virtual Factory: Managing Supply Chain Communications (free forum F11) will demonstrate OEM/EMS collaboration using the IPC Product Data eXchange (PDX) standards in conjunction with RosettaNet manufacturing Partner Interface Process® (PIP®) specifications, all of which were initiated via an IPC/NEMI partnership. The panel, scheduled from 10:45 a.m. to 12:15 p.m. on Tuesday, April 1, will provide demonstrations and discuss lessons learned from implementations.

im using a volt tester on my 2000 watt insignia amp and when cars on the wires read around 14.46 not 12?
Question by : im using a volt tester on my 2000 watt insignia amp and when cars on the wires read around 14.46 not 12?
i bought a car that was pre wired so i hook up my 2 12 inch 2400 watt dvc boss phantoms with my 2000 watt insignia amp they bumped for about 5 seconds then cut out and now i get no power to my subs. so i did the trial and error, im at a dead end so i bought a digital multimeter to test the volts flowing threw the wires im pretty shure its supposed to be 12 volts when cars running. when i tested the battery wire was at est. 14.46 and remote wire est, 14.44. i also tested the speaker wire outs on the amp and they read lower than 12? im good at installing systems and don’t believe in spending 40 dollars a half hour to look at my system if i can fix it myself and im always looking for more experience. can someone please let me know if u know whats wrong with my system! THANK YOU!
yes i have a 99 cadillac seville and the battery is under the back seat i checked all the wires fuses for crimps splices ect. nothing and im running all this off my stock bose stereo, all wiring was installed professionally at raxx audio (herd nothing but awsome about them.) grounded to chassie and to bare metal, ive changed audio cabels.
ALSO when i have everything hooked up except the rca the protect lite comes on (good) so when i plug them in the lite is supposed to turn green for power but the red goes off and green never comes on?
Best answer:
Answer by drumerdanc
your car is supposed to make more than 12 volts. 14 volts is not uncommon at all. Check all your fuses, check your ground, and check your RCAs. A good ground is always important for high drain or sensitive electronic devices.

This mechanic came out with a voltage tester to check what the problem was with my coach. Having worked in the tech industry debugging servers, this road call felt more familiar to me than when a mechanic comes out to work on a broken down diesel coach. Even then, the problem is sometimes a computer, rather than a mechanical part.
