J1772 Connectors

 J1772 Connectors  is a North American standard for electrical connectors for electric vehicles maintained by the Electriccarpartscompany and has the formal title " J1772 Connectors. Electric Vehicle Conductive Charge Coupler. It covers the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. The intent is to define a common electric vehicle conductive charging system architecture including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.

The main stimulus for the development of J1772 Connectors came from the California Air Resources Board. Formerly electric vehicles like the General Motors EV1 had used inductive charger couplers. These were ruled out in favor of conductive coupling to supply electricity for recharging with the California Air Resources Board settling upon the electriccarpartscompany standard as the charging interface for electric vehicles in California in June 2001.Av con manufactured a rectangular connector compliant with that J1772 Connectors specification that was capable of delivering up to 6.6 kW of electrical power. Photos and description of this old-revision rectangular "AV Con connector" and "AV Con inlet".

The J1772 standard includes several levels of shock protection, ensuring the safety of charging even in wet conditions. Physically, the connection pins are isolated on the interior of the connector when mated, ensuring no physical access to those pins. When not mated, J1772 connectors have no voltage at the pins, and charging power does not flow until commanded by the vehicle.

The power pins are of the first-make, last-break variety. If the plug is in the charging port of the vehicle and charging, and it is removed, the control pilot and proximity detection pin will break first causing the power relay in the charging station to open, cutting all current flow to the J1772 plug. This prevents any arcing on the power pins, prolonging their lifespan. The proximity detection pin is also connected to a switch that is triggered upon pressing the physical disconnect button when removing the connector from the vehicle. This causes the resistance to change on the proximity pin which commands the vehicle's onboard charger to stop drawing current immediately before the connector is pulled out.

Inverters

A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in the conversion process.

Input voltage

A typical power inverter device or circuit requires a relatively stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include:

• 12 VDC, for smaller consumer and commercial inverters that typically run from a rechargeable 12 V lead acid battery.
  
• 24 and 48 VDC, which are common standards for home energy systems.
  
• 200 to 400 VDC, when power is from photovoltaic solar panels.
  
• 300 to 450 VDC, when power is from electric vehicle battery packs in vehicle-to-grid systems.
  
• Hundreds of thousands of volts, where the inverter is part of a high voltage direct current power transmission system.
  

Output waveform

An inverter can produce a square wave, modified sine wave, pulsed sine wave, pulse width modulated wave (PWM) or sine wave depending on circuit design. The two dominant commercialized waveform types of inverters as of 2007 are modified sine wave and sine wave.

There are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.

Square wave

This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.

Output voltage 

The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.

Some also allow selectable or continuously variable output voltages.
