Frequently Asked Questions

Q1: What is a 6.6kW onboard charger (OBC) and how does it work?

An onboard charger (OBC) is a device installed inside an electric vehicle or machine that converts AC power from a standard wall outlet or charging station into DC power to charge the battery pack. The Deligreen 6.6kW OBC accepts AC input from 90V to 264V and delivers up to 6.6kW of continuous DC output, making it suitable for fast, efficient charging of EV battery packs in vehicles, golf carts, forklifts, and marine applications.

Q2: What CAN bus speeds does this onboard charger support?

This charger supports three standard CAN bus communication speeds: 125K, 250K, and 500K bps. You select the appropriate variant at checkout to match your BMS communication protocol. CAN bus integration allows the charger to receive real-time data from the Battery Management System (BMS) - including target voltage, current limits, and state of charge - enabling intelligent, adaptive charging.

Q3: Is this charger compatible with both 120V (US) and 230V (European) power grids?

Yes. The Deligreen 6.6kW OBC features a universal AC input range of 90V to 264V at 45-65 Hz, making it fully compatible with both North American 120V/240V and European 230V grid standards. No manual switching or external transformer is required - the charger auto-detects and adapts to the input voltage automatically.

Q4: What does IP67 waterproof rating mean for an EV charger?

IP67 is an international protection rating defined by IEC 60529. The 6 means the unit is completely dust-tight, and the 7 means it can withstand immersion in water up to 1 meter deep for 30 minutes without damage. For EV chargers, this means the unit is safe for use in rain, high-humidity environments, marine applications, and outdoor installations where exposure to moisture is unavoidable.

Q5: Which battery chemistries are compatible with this charger?

The Deligreen 6.6kW OBC is compatible with a wide range of lithium battery chemistries, including LiFePO4 (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt), as well as other lithium-based battery types. Charge profiles are fully programmable, allowing you to set the correct charge voltage and current limits for your specific battery pack. Contact us for custom charge profile configuration support.

Q6: Can I use this charger without CAN bus - for example, with a simple enable/disable signal?

Yes. In addition to CAN bus variants (125K, 250K, 500K), there is an Enable variant available that uses a simple enable/disable control signal instead of CAN communication. This is ideal for simpler BMS setups, golf carts, forklifts, or any application where CAN bus integration is not required. The charger starts and stops charging based on the enable signal state.

Q7: How do I install this onboard charger in a DIY EV conversion?

Installation involves connecting the AC input to your vehicle's charge port (J1772, Type 2, or direct wiring), connecting the DC output to your battery pack (observing correct polarity and fusing), and wiring the CAN bus or enable signal to your BMS. The charger mounts via its standard bolt pattern and requires adequate airflow for the forced-air cooling fan. We provide wiring diagrams and CAN bus protocol documentation upon request - email us at deligreencharger@gmail.com.

Q8: What safety protections does this charger include?

The Deligreen 6.6kW OBC includes multiple layers of protection to safeguard both the charger and your battery pack, including: over-voltage protection, over-current protection, short-circuit protection, over-temperature protection with automatic recovery, and intelligent temperature compensation to prevent overcharging or undercharging due to ambient temperature changes. The LED indicator also provides real-time status and fault diagnostics.

Q9: Is this charger suitable for marine and boat applications?

Yes. The IP67 fully sealed enclosure makes this charger an excellent choice for marine and boat EV applications. It is protected against water ingress, humidity, and salt spray - common challenges in marine environments. Its wide operating temperature range (-40C to +85C) and automotive-grade vibration resistance (QC/T 895-2011) further ensure reliable performance in demanding on-water conditions.

Q10: Do you provide technical support and documentation for EV integrators?

Absolutely. Deligreen Charger provides full technical support for professional EV integrators and DIY builders, including wiring diagrams, CAN bus protocol documentation, charge profile configuration guidance, and integration consulting.
