How does an EV charger work?
In North America, the standard EV charger uses a SAE J1772 plug—also known as a J plug—which attaches to the EV’s port. The standard SAE J1772 plug is compatible with all EVs and PHEVs, with the exception of Tesla vehicles. An adaptor to make the J1772 plug work with Teslas is typically included with the vehicle or available for purchase online.
Both the EVSE and iEVSE stations can be installed by plugging them into a 240v outlet or having a certified electrician hardwire the unit into a powersource. Once installed, they will be ready for use immediately.
If you’ve purchased an iEVSE and would like to use a network service provider to track your usage and/or connect with your local utility, that provider will need to be set up.
What is the difference between Level 1 and Level 2 EV chargers
The biggest difference between Level 1 and Level 2 EV chargers is the speed of charge. EvoCharge’s Level 2 EV chargers have a typical charge time of 3-to-8 hours—that means you get up to 32 miles of driving range per hour of charging. Level 1 chargers, which come with the vehicle, have a typical charge time of 11-to-20 hours, or only 4 miles of driving range per hour of charging.What does OCPP mean？
Open Charge Point Protocol (OCPP) is an application protocol for communication between the Electric Vehicle (EV) charging station and a central management system, also known as a charging station network. The unique thing about true OCPP chargers is that you aren’t locked into using a specific network. Other non-OCPP EV charging stations won’t work unless you use a specific network that can communicate with that specific charger. OCPP chargers give you the freedom to choose the network you want to use and switch companies laterEV Charging Station Classification
1.What is a charging pile?
Charging piles, whose function is similar to that of gas pumps inside gas stations, can be fixed on the ground or walls, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. Charging piles can be classified in different ways as follows.
1.1 According to the installation method
It can be divided into floor-mounted charging piles and wall-mounted charging piles. Floor-mounted charging posts are suitable for installation in parking spaces not close to the wall; wall-mounted charging posts are suitable for installation in parking spaces close to the wall.
1.2 According to the installation location
It can be divided into public charging piles and special charging piles. Public charging pile is a charging pile built in public parking lot (library) combined with parking space to provide public charging service for social vehicles; special charging pile is a charging pile built in unit (enterprise) own parking lot (library) for internal personnel of unit (enterprise), and a charging pile built in individual own parking space (library) to provide charging for private users. Charging piles are usually built in combination with parking spaces in parking lots (garages).
1.3 According to the number of charging interfaces
It can be divided into one pile with one charge and one pile with multiple charges.
1.4 According to charging mode
Charging pile can be divided into DC charging pile, AC charging pile and AC/DC integrated charging pile.
1.5 According to charging speed
There are two charging methods: regular charging (slow charging) and fast charging (fast charging). Charging time varies according to different vehicle batteries, ambient temperature, etc. Slow charging is generally in 5-10 hours full, fast charging can be in 20-30 minutes full 80%, 1 hour completely full.
2 the charging pile industry chain, mainly divided into equipment manufacturers and charging operators.
2.1 Charging pile equipment itself does not have too high technical content, unified standards, good compatibility, stable quality, and proper construction can be. The competitive differences are mainly reflected in the stability of the equipment produced, cost control, brand reputation and bidding ability.
ev dc fast charging station
Currently, there are three main charging methods for electric vehicles: off-board charger, which is installed outside the body of an electric vehicle and converts AC power to DC power; on-board charger, which is fixedly installed on an electric vehicle and converts AC power to DC power; and AC charging spot, which is a special power supply device that uses conduction to provide AC power to an electric vehicle with an on-board charging device.
As shown in the figure, the advantage of AC charging spot is that it saves the cost of charging post and is more flexible and convenient, but the charging power is low, and it increases the weight and design complexity of the body. DC charging, on the other hand, can output a higher power current, resulting in super fast charging.
AC charging piles or on-board chargers are generally 3.5KW, 7KW , 15KW power charging, while DC charging supports 20kW, with general specifications of 30KW, 60KW, 80KW, 120KW, 150KW, 180KW, etc.
The on-board 3.3 kW charger can charge a depleted 16 kWh battery pack in a PHEV to 95% in approximately 4 hours at 240 V power.
For AC charging stations, the Society of Automotive Engineers (SAE) has established standards, which are
Level 1 EVSE (typically residential chargers) use a household 120 VAC / 230 VAC power supply that can provide current in the range of 12 A to 16 A and can charge a 24 kWH battery in 12 to 17 hours.
Level 2 EVSE (typically used in commercial locations such as malls, offices, etc.) uses a multi-phase 240 VAC power supply to power more powerful vehicle chargers with currents between 15 A and 80 A and charges a 24 kWH battery in approximately eight hours.
Level 3 DC Charging Post: This type of charging station uses an external charger to supply up to 400 A of high-voltage (300 V-750 V) DC power directly to the vehicle battery.
Level 3 DC charging posts do not require on-board charge control because they are DC powered and have a higher output current power, with a typical 24 kWH battery taking less than 30 minutes to charge.
As defined by the International Electrotechnical Commission (IEC) mode definitions (IEC 62196 standard), then there are four charging modes.
Mode 1 - Slow charging from a regular power outlet (single-phase or three-phase).
Mode 2 - slow charging from a regular power outlet, but equipped with EV-specific protection devices.
Mode 3 - Slow or fast charging from a specific EV multi-pin socket with control and protection (according to SAE J1772 and IEC 62196 standards).
Mode 4 - Fast charging using special charger technology such as Charge de Move (CHAdeMO).
In addition, four plug types are available.
Type 1 - SAE J1772-2009 automotive plug specification for single-phase vehicle couplers.
Type 2 - Single-phase and three-phase vehicle couplers with VDE-AR-E 2623-2-2 plug specification.
Type 3 - Single-phase and three-phase vehicle couplers with safety shutters, a proposal of the EV Plug Alliance.
Type 4 - Fast charging couplers for special systems (e.g. CHAdeMO).
Safety codes and standards
Both on-board and off-board chargers need to comply with various codes set by regional governments and utility commissions, depending on where they are deployed. In general, these are the key safety and operational requirements that are mandated, specifically.
Electromagnetic compatibility (EMC) emission and immunity (US: FCC Part 15 Class A; European Union (EU) European Standards (EN): EN 55011, EN 55022 and IEC 61000-4).
Efficiency (96% and above).
Harmonic current total harmonic distortion (iTHD) <7% (in accordance with Institute of Electrical and Electronics Engineers [IEEE] 519 requirements).
Enclosure protection (e.g. IP54).
Connector type (CHAdeMO, Combined Charging System (CCS) 1 (SAE J1772 combined), CCS2 (IEC 61851-23), GB/T standard, etc.
Safety compliance (in the U.S. including: Underwriters Laboratories (UL) 2202, UL 2231-1 and UL 2231-2. in Europe: IEC 62196, IEC 61851, ConformitéEuropéene (CE)).
