At present, there are two main types of charging piles for electric vehicles. One is the public operating charging pile, and the other is the owner’s personal charging pile. The portable charger does not require a fixed parking space and can be carried with the car flexibly. It is an important choice for many electric vehicle owners. Conventional charging is to use the portable charging device equipped with the car for charging, and can use a household power supply or a dedicated charging pile power supply. The charging current is relatively small, generally around 16-32A, and the current can be DC or two-phase AC and three-phase AC, so the charging time is 5 to 8 hours depending on the capacity of the battery pack.

After slow charging is "plugged in", the AC power supply equipment detects whether the gun head is connected well through the CC (connection confirm function)/CP (control pilot function) loop voltage detection device, and after confirming that there is no problem, the high-voltage contactor is closed to supply power to the OBC (On-board Charger) input.
After the OBC is powered on and self-checks without faults, it outputs low-voltage auxiliary power, and the BMS (Battery Management System) and VCU (Vehicle Control Unit) are activated.
When the VCU detects the "charging activation signal" and the BMS sends out the "AC charging connection", it pulls in the "slow charging high-voltage relay" and controls the slow charging electronic lock to execute the "locking logic".
The BMS detects whether the car end gun head is connected well through the CC loop voltage, and obtains the "rated capacity of the cable"; confirms the maximum power supply current of the AC power supply equipment through the detection of the PWM (Pulse-Width Modulation) signal of the CP loop; the BMS takes the minimum value of the former two and the "rated input current value" sent by the OBC, and sets it as the "maximum allowable input current value" of the OBC, and sends the charging voltage and current information to the OBC.
The BMS pulls in the charging relay and sends the "charging machine control command" through the CAN (Controller Area Network) message. After receiving it, the OBC starts charging.
When the BMS detects that the battery has reached the "full charge state" or receives the "charging machine terminates charging message" sent by the OBC, it disconnects the charging relay; the VCU detects that the BMS has disconnected the charging relay, and disconnects the "slow charging high-voltage relay" and controls the slow charging electronic lock to execute the "unlock logic".
Differences Between AC Charging Pile and DC Charing Pile
Generally speaking, the DC charging pile is relatively large, which is because there is a need for AC to DC power supply modules inside. The higher the charging power, the more the number of modules, and the larger the pile. Moreover, the gun head of the charging pile is different. The DC charging pile uses a 9-wire plug, while the AC charging pile uses a 7-wire plug.
Then let's talk about the AC electric vehicle charging pile. This kind of charging pile is slower than the DC charging pile, so people also call it slow charging. This kind of charging pile is a power supply device specially designed to provide AC power for the on-board charger. That is to say, the AC charging pile only provides power output and has no charging function. It needs to connect the on-board charger to charge the electric vehicle.
Because the complexity of the structure varies greatly, the manufacturing cost of DC charging piles will be higher, so the price of DC charging piles today will be significantly higher than that of AC charging piles.
- AC pile (commonly known as slow filling pile) is usually small in power. The common models on the market are 7kW and 3.5kW, which are suitable for private cars to be installed in their own fixed parking spaces.
- DC piles (commonly known as quick-filled piles) are usually above 30kW. Generally, the capacity of the pile is expressed according to the superimposed number of modules contained in the pile (usually 15kW for each module). 45kW means 3 modules, 60kW means 4 modules, and so on. At present, the majority of DC piles in the market are 60kW.
- In terms of charging efficiency, the DC pile is to directly inject DC into the vehicle power battery. DC has a fast-charging speed for DC and may damage the battery (there is no scientific conclusion yet). The AC pile needs to be converted by the on-board charger. DC-AC-DC has a slow charging speed, which is beneficial to the battery life, but there is a problem of power loss in power conversion.
- From the perspective of construction cost, because DC piles have greater technical requirements for capacitors, when investing in the construction of charging stations with DC piles as the main body, it is often necessary to increase the capacity of electric power, and there are more safety problems. In terms of site acceptance and safety management, DC pile groups are often more complex and rigorous. AC piles are more flexible. Many cities and properties allow AC piles to be installed in underground garages, but very few are willing to build DC piles in underground garages, mainly based on safety considerations.
- The AC pile is essentially a vehicle charger. Due to the more built-in DC piles, the modules in the DC pile are not only costly, but also have technical barriers. It is also an important hub to determine how the charging pile and the intelligent and networked electric vehicle work together, so it is more worthy of research and investment by all parties.
Installation Method
Installing a portable charging pile requires careful planning and consideration to ensure its optimal functioning and convenience. Follow these steps for a successful installation:
Determine the Location
Choose a suitable location for the charging pile, ensuring it is easily accessible to electric vehicle owners. Consider factors such as proximity to parking spots and availability of power supply.
Obtain Permits and Approvals
Check local regulations and obtain any necessary permits or approvals before installation. Compliance with safety standards and regulations is essential.
Select a Mounting Option
Portable charging piles can be mounted on the ground or can be wall-mounted depending on the available space and convenience. Ensure proper stability and secure mounting.
Connect Power Supply
Ensure a reliable and adequate power supply to the charging pile. Consult an electrician to determine the suitable power source and connection requirements for the charging pile.
Test
Before making the charging pile operational, conduct thorough testing to ensure its safety and effectiveness.
Precautions
While using portable charging piles, it is essential to take certain precautions:
Follow Manufacturer Guidelines
Adhere to the manufacturer's guidelines and instructions while operating the portable charging pile to ensure safety and prevent any damage.
Avoid Unauthorized Access
Prevent unauthorized access to the charging pile to avoid any tampering or potential hazards.
Regular Maintenance
Schedule regular maintenance and inspection of the charging pile to detect any faults or issues. Promptly address any repairs or malfunctions identified.
Emergency Preparedness
Keep a contact list of emergency services and ensure proper firefighting equipment is readily available in case of any emergencies or accidents.
Compatibility: Ensure that the charging pile is compatible with your electric vehicle's charging port. Most electric vehicles in use today use the standard Type 1 (SAE J1772) or Type 2 (IEC 62196) connectors, but it's essential to double-check compatibility with your specific vehicle model.
Charging Speed: Consider the charging speed offered by the charging pile. Different charging piles provide varying levels of power output, ranging from standard Level 1 (120V AC) chargers to Level 2 (240V AC) chargers with higher charging speeds. Choose a charging pile that meets your needs for charging time and convenience.
Safety Features: Prioritize safety features such as overcurrent protection, overvoltage protection, and short-circuit protection to ensure safe charging operations. Look for charging piles that meet relevant safety standards and certifications.
Ease of Use: Opt for a charging pile that is user-friendly and easy to operate. Features such as intuitive interface or LED indicators can enhance the user experience and simplify the charging process.
Smart Connectivity: Consider a charging pile with smart connectivity features such as Wi-Fi or Bluetooth connectivity, smartphone app integration, and remote monitoring capabilities. These features allow you to monitor charging status, schedule charging sessions, and receive notifications remotely.
