Charging System Pdf UPDATED Free Download

My wife recently bought a brand new 2017 Toyota Camry. We bought the car and after a week we noticed that it would say "check charging system" when we put the keys in the ignition and turned the keys to on (not starting engine). We didn't have time to go to our dealership because the next day we went on vacation out of the country. We just got back and I took her car to the Toyota dealership and they said that's normal and nothing to worry about. I did a little bit of digging online and others have said that the battery isn't holding a charge, the alternator is going bad, or that it's perfectly normal... Anyone know which one is it? Thanks in advance :)

Purkeys liftgate charging systems improve the charging of liftgate batteries by utilizing a DC/DC Converter to boost the voltage for optimal charging. The DC/DC Converter also compensates for temperature as well as for voltage drop and provides the best voltage to the remotely located liftgate batteries. The result is well-charged liftgate batteries that will last longer and have ample power for liftgate operation.

The charging infrastructure industry has aligned with a common standard called the Open Charge Point Interface (OCPI) protocol with this hierarchy for charging stations: location, EV charging port, and connector. The Alternative Fuels Data Center and the Station Locator use the following charging infrastructure definitions:

Charging equipment for EVs is classified by the rate at which the batteries are charged. Charging times vary based on how depleted the battery is (i.e., state-of-charge), how much energy it holds (i.e., capacity), the type of battery, the vehicle's internal charger capacity, and the type of charging equipment (e.g., charging level, charger power output, and electrical service specifications). The charging time can range from less than 20 minutes using DC fast chargers to 20 hours or more using Level 1 chargers, depending on these and other factors. When choosing equipment for a specific application, many factors, such as networking, payment capabilities, and operation and maintenance, should be considered.

Alternating Current (AC) Level 1 equipment (often referred to simply as Level 1) provides charging through a 120 volt (V) AC plug. Most, if not all, EVs will come with a portable Level 1 cordset, so no additional charging equipment is required. On one end of the cord is a standard NEMA connector (for example, a NEMA 5-15, which is a common three-prong household plug), and on the other end is an SAE J1772 standard connector (often referred to simply as J1772, shown in the above image). The J1772 connector plugs into the car's J1772 charge port, and the NEMA connector plugs into a standard NEMA wall outlet.

Level 1 charging is typically used when there is only a 120 V outlet available, such as while charging at home, but can easily provide charging for most of a driver's needs. For example, 8 hours of charging at 120 V can replenish about 40 miles of electric range for a mid-size EV. As of 2022, less than 1% of public EV charging ports in the United States were Level 1.

AC Level 2 equipment (often referred to simply as Level 2) offers charging through 240 V (typical in residential applications) or 208 V (typical in commercial applications) electrical service. Most homes have 240 V service available, and because Level 2 equipment can charge a typical EV battery overnight, EV owners commonly install it for home charging. Level 2 equipment is also commonly used for public and workplace charging and can operate at 40 to 80 amperes (Amp). Most residential Level 2 chargers operate at up to 30 Amps, delivering 7.2 kW of power. These units require a dedicated 40-Amp circuit to comply with the National Electric Code requirements in Article 625. As of 2022, nearly 80% of public EV charging ports in the United States were Level 2.

Level 2 charging equipment uses the same J1772 connector that Level 1 equipment uses. All commercially available EVs in the United States have the ability to charge using Level 1 and Level 2 charging equipment.

Vehicles with a J3400 (also referred to as NACS, or North American Charging Standard) connector (currently only Tesla vehicles) can use the connector for all charging levels, including Tesla's Level 2 Destination Chargers and chargers for home. All Tesla vehicles come with a J1772 adapter, which allows them to use non-Tesla Level 2 charging equipment.

Direct-current (DC) fast charging equipment (typically a three-phase AC input) enables rapid charging along heavy traffic corridors at installed stations. As of 2022, more than 20% of public EV charging ports in the United States were DC fast chargers. The availability of DC fast charging is expected to increase as a result of federal funding to build a national EV charging network, such as the National Electric Vehicle Infrastructure Formula Program or national Alternative Fuel Corridors grant program. Additionally, DC fast charging is projected to increase due to fleets adopting medium- and heavy-duty EVs (e.g., commercial trucks and vans and transit), as well as the installation of fast charging hubs for transportation network companies (e.g., Uber and Lyft) and other applications.

The CCS connector (also known as SAE J1772 combo) lets drivers use the same charge port with AC Level 1, Level 2, and DC fast charging equipment. The only difference is that the DC fast charging connector has two additional bottom pins. Most EV models on the market can charge using the CCS connector.

Another standard (SAE J3068) was developed in 2018 for higher rates of AC charging using three-phase power, which is common at commercial and industrial locations in the United States. Some components of the standard were adapted from the European three-phase charging standards and specified for North American AC grid voltages and requirements. In the United States, the common three-phase voltages are typically 208/120 V, 480/277 V. The standard targets power levels between 6 kW and 130 kW.

Extreme fast chargers (XFC), such as the SAE DC Level 2 standard, are capable of power outputs of up 350 kW and higher and are rapidly being deployed in the United States light-duty and select medium-duty applications (e.g., for in-route charging of electric buses). XFC will also support long-dwell overnight charging for medium- and heavy-duty vehicle applications. A 2022 report looks at the requirements for charging stations that could support in-route charging for heavy-duty EVs.While XFC are currently available from several charging manufacturers, the U.S. Department of Energy's Vehicle Technologies Office is pursuing research that will bridge the technology gaps associated with implementing XFC networks in the United States. A 2017 report highlights technology gaps at the battery, vehicle, and infrastructure levels. In particular, many EVs on the roads today are not capable of charging at rates higher than 150 kW. However, vehicle technology is advancing, and most new EV models will be able to charge at higher rates, enabling the use of XFC. You can find additional resources on EV charging and advanced charging system research efforts from the National Renewable Energy Laboratory. For answers to frequently asked questions about the Megawatt Charging System and SAE J3271, see the fact sheet on Charging for Heavy-Duty Electric Trucks from Argonne National Laboratory.

Inductive charging equipment, which uses an electromagnetic field to transfer electricity to an EV without a cord, has been introduced commercially for installation as an aftermarket add-on. Some currently available wireless charging stations operate at power levels comparable to Level 2, though this technology is more common for transit or other fleet operations at higher power levels comparable to DC fast. The U.S. Department of Energy is conducting research to investigate the feasibility of high-powered wireless charging. More information on inductive charging research efforts is available from the National Renewable Energy Laboratory.

You removed alternator. So you flexed all wires. The charging cable and the sense wire cable that controls alternator. They were untouched before you changed alternator. Could be as simple as broken wire inside connector. Happened to me. Had to replace plug. 006ab0faaa
