Understanding IS 17017-2-6 vs IS 17017-2-7, the Type 6 (LEVDC) & Type 7 (LECCS) Connectors for Light Electric Vehicles

India’s EV ecosystem is evolving rapidly, and so are the charging standards that power it. Two key specifications of connectors IS 17017-2-6 and IS 17017-2-7 are shaping how Electrical Two-wheelers (2W) and Three-wheelers (3W) connect to chargers driving interoperability.  Common name for these connectors is Type 6 connector and Type 7 connector.

Brief Overview of Indian LEV Standard Connectors

As the electric vehicle (EV) charging ecosystem grows, understanding the pin configuration differences among these connector types is critical for manufacturers, infrastructure providers, and users alike. At EVQPoint Solution, we specialize in designing adaptable DC fast charging solutions that work seamlessly across both the standards as per end-user fast charging requirements.

Overview of Type 6 and Type 7 Connectors

• Type 6 Connector: Primarily based on the EPTW-CHAdeMO standard, mainly for DC fast charging.

• Type 7 Connector: A newer, hybrid design driven by India, combining features both AC and DC charging in a unified interface.

Pin details of Type 6 (IS17017-2-6) and Type 7 (IS17017-2-7) connectors

Type-6 interface Pins and it's functions:

Position Numbers*	Symbol	U max(V)	I max(A)	Function
1	DC +	120	100	DC +
2	DC -	120	100	DC -
3	CP	30	2	Control Pilot
4	COM 1	30	2	Communication 1 (+)
5	COM 2	30	2	Communication 1 (-)
6	AUX 1	30	2	Auxiliary power supply 1 (+)
7	AUX 2	30	2	Auxiliary power supply 1 (-)

* The position number does not indicate the physical location or identification of the contact within the accessory

Type-7 interface pins and its functions:

Position Numbers *	Symbol	U max(V)	I max(A)	Function
1	DC +	120 DC	100	DC +
2	DC -	120 DC	100	DC -
3	L1	240 AC	32	Live
4	N	240 AC	32	Neutral
5	PE	**	Protective Earth
6	CP	30	2	Control Pilot
7	PP	30	2	Proximity pilot
8	CAN+	30	2	Communication 1 (+)
9	CAN-	30	2	Communication 1 (-)

** rated for the highest fault current

Key Major Differences:

Power

• Type 6 is a dedicated DC Charging Connector defined  for 100A rating, but available till 125A current rating.

• Type 7 integrates both AC and DC charging in a unified charging interface and available till 100A current rating.

  
  

Communication Pins

• Both Type 6 and Type 7 uses CAN bus (CAN High and CAN Low pins) for communication after the initial CP handshake.

AC Charging Capability

• Type 7 supports AC charging with distinct pins for AC single phase interface till 32A of current

  
  

Latch

• Type 6 connectors come with both mechanical and electromechanical latches for charger side and there is NO latch on the vehicle side.

• Type 7 connectors doesn’t have latch on charger side but are energized with latch present on vehicle side connector.

Understanding the differences in pin configuration between Type 6 and Type 7 EV connectors is essential for ensuring compatibility, safety, and performance in electric vehicle charging systems. As the EV industry continues to evolve, staying informed about connector standards helps both consumers and infrastructure providers make smarter, future-proof choices.
