Why Are 72V OBC Chargers Popular in Korea?
Korea has a variety of compact electric vehicles, neighborhood EVs, utility EVs and converted electric vehicles using relatively low-voltage battery platforms.
One good example is the MaiV M1, a Korean compact electric vehicle. The current MaiV service center lists the M1 with a 10kWh Samsung SDI battery, a 72V battery system, and 220V AC slow charging through a 5-pin J1772 connection. (MaiV)
This type of vehicle creates a clear requirement for a reliable 72V charging solution.
For EV owners, workshops and EV conversion companies, the key question is not simply:
"Is this a 72V charger?"
The more important question is:
"Can the charger communicate correctly with the vehicle's BMS?"
That is where CAN communication becomes especially important.
TC HK-MF-72-40: 3.3kW / 72V / 40A
The TC HK-MF-72-40 is a compact air-cooled on-board charger designed specifically for 72V-class EV applications.

Why CAN Communication Matters
A modern EV charger is not simply an AC-to-DC power supply.
The OBC needs to work together with the vehicle's Battery Management System (BMS).
Through CAN communication, the charger can receive charging-related commands and exchange information with the vehicle control system.
The HK-MF series supports CAN communication, including 250Kbps and 500Kbps CAN bus configurations, as well as CAN wake-up and diagnostic functions. (ELCON Chargers)
This makes the HK-MF-72-40 particularly suitable for EV applications where the charger needs to communicate with the vehicle rather than simply output a fixed voltage and current.
CAN 2445 & CAN 2094 for Korean EV Applications
For the Korean market, Deligreen supplies the TC HK-MF-72-40 with specific CAN configurations including CAN 2445 and CAN 2094.
These configurations are particularly interesting because Korean customers have repeatedly selected these CAN versions for their 72V EV charging applications.
Available Configurations
TC HK-MF-72-40 CAN 2445
- 72V platform
- 3.3kW charging power
- Up to 40A output
- CAN communication
- Suitable for compatible 72V lithium battery systems
- Specific CAN configuration for vehicle/BMS communication
TC HK-MF-72-40 CAN 2094
- 72V platform
- 3.3kW charging power
- Up to 40A output
- CAN communication
- Suitable for compatible 72V lithium battery systems
- Specific CAN configuration for vehicle/BMS communication
Important Compatibility Note
CAN protocol compatibility is critical.
A 72V battery does not automatically mean that every 72V CAN charger will work with every 72V EV.
Before ordering, we recommend confirming:
- Battery nominal voltage
- Maximum battery charging voltage
- BMS CAN communication
- CAN baud rate
- CAN ID / charging protocol
- CAN communication requirements
- Charger connector and pinout
- Required charging current
For customers who already know their CAN configuration, CAN 2445 and CAN 2094 versions are available for specific applications.
Compact Size, High Power and IP67 Protection
One of the advantages of the HK-MF-72-40 is its compact design.
The charger provides 3.3kW of charging power while weighing only around 4.6kg, making it suitable for applications where installation space is limited. (On-Board Charger)
The charger also features an IP67-rated enclosure, helping protect the electronics against dust and water ingress in demanding vehicle environments. (Deligreen Charger Store )
The charger is forced-air cooled and includes temperature protection to help maintain safe operation during charging.
3.3kW Charging: What Does It Mean for a 72V EV?
For a 72V battery system, a 40A charger provides approximately:
72V × 40A = 2.88kW
Because the actual charging voltage increases during charging, the HK-MF-72-40 can deliver up to approximately 3.3kW under suitable AC input conditions.
For a 10kWh-class battery, such as the battery capacity listed for the MaiV M1, a 3.3kW OBC can provide a useful balance between charging speed, charger size and vehicle electrical-system requirements. (MaiV)
Actual charging time will depend on battery state of charge, charging strategy, BMS limits, temperature and charging losses.
Who Is the HK-MF-72-40 Suitable For?
The TC HK-MF-72-40 can be considered for:
1. Korean EV Repair Workshops
If you repair or maintain 72V electric vehicles, having a compatible replacement OBC can significantly simplify charger replacement projects.
2. EV Conversion Companies
For electric vehicle conversion projects using 72V lithium batteries, a programmable CAN-controlled OBC can provide more flexibility than a basic fixed-output charger.
3. EV Parts Distributors
The HK-MF-72-40 is a compact and popular 72V OBC option for distributors serving the EV aftermarket.
4. EV Owners Looking for a Replacement Charger
If your original OBC has failed, the most important step is to identify the battery voltage, charging voltage, current requirement and CAN protocol before selecting a replacement.
Why Korean Customers Choose TC HK-MF-72-40
Based on our sales experience, Korean customers have repeatedly selected the HK-MF-72-40 for 72V EV applications.
The reasons are straightforward:
72V platform + 3.3kW power + 40A output + CAN communication + compact size + IP67 protection
