Proximity PilotThe proximity pin, PP (also known as plug present), as shown in the SAE J1772 example pinout, describes the switch, S3, as being mechanically linked to the connector latch release actuator. During charging, the EVSE side connects the PP–PE loop via S3 and a 150 Ω R6; when opening the Read More

The signaling protocol has been designed for the following charging sequence.supply equipment signals presence of AC input powervehicle detects plug via proximity circuit (thus the vehicle can prevent driving away while connected) and can detect when latch is pressed in preparation for plug removal.

In 2011, SAE developed a J1772/CCS Combo Coupler variant of the J1772-2009 connector in order to also support the Combined Charging System standard for direct current (DC) fast charging, which includes the standard 5-pin J1772 connector along with an additional two larger pins to support fast DC cha Read More

Charging piles are divided into DC charging piles and AC charging piles.DC charging stationCommonly known as "fast charging", it is fixedly installed outside the electric vehicle and connected to the AC power grid. It uses a three-phase four wire 380V frequency stable frequency of 50HZ, and can also Read More

The battery swapping mode of pure electric vehicles is a highly concerned topic, which involves multiple aspects such as the energy replenishment methods of electric vehicles, the development of battery technology, the layout of the industrial chain, and environmental protection. In the context of t Read More

Solar inverter is an electronic device that converts direct current (DC) to alternating current (AC). Some people get confused when choosing a solar inverter and don't know which solar inverter is right for them, off-grid, grid-tied or hybrid inverter? Therefore, we will tell you the difference betw Read More

Analysis of AC Slow Charging CircuitGrid power supply, also known as the charging station, has no interface between the charging station and the cable, which is a typical feature of connection method C.Vehicle Coupler, which is the vertical dashed line in the middle of the vehicle interface, is the Read More

NASN TS series sine wave inverter is especially designed and produced for the enterprises in electrical power system and rail transportation, base stations, transportation, electric power, industry and other industries according to their actual requirements under the condition of not only considerin Read More

The price of battery grade lithium carbonate has sharply declined, and the important raw cost price of electric vehicles has completely collapsed.So the sales price of electric vehicles should decrease correspondingly . However, the sales price has not decreased, but has been continuously increasing Read More
