Which 6.6 kW model should I choose?

Match the DC output range to your pack’s nominal and maximum voltage, then confirm current limits and derating in the official manual.

Do these chargers require CAN?

CAN control is strongly recommended for managed charging, fault handling, and enforcing limits based on BMS and AC source constraints.

Any AC input considerations?

Verify branch circuit capacity and install per the manual. Implement CAN-based derates where necessary to meet site power limits.

Why these chargers

Sealed & compact

Fully potted, IP-rated construction for harsh environments; small footprint suits tight bays.

CAN control

BMS/VCU-managed charge profiles, fault handling, and derates via CAN for clean system integration.

Protection built-in

Thermal sensing with automatic cutback, comprehensive electrical protections, and status reporting.

Technical snapshot

Power	6.6 kW class (model dependent)
Control	CAN bus (per model generation)
Cooling	Conduction / sealed potting
Ingress	IP-rated (see manual)
Thermal behavior	On-board sensing with automatic derate/reset after cool-down
AC input	Wide-range AC (verify per manual and branch circuit capacity)
DC output	See models table above

Use the official manuals for exact input ranges, output currents, CAN maps, and derating behavior.

Ordering & integration notes

Select the HK-LF / HK-J model that matches your pack voltage and charge strategy.
Plan CAN integration with your BMS/VCU; implement current/voltage/temperature limits and any AC-side derates.
Mount to a thermally suitable surface and follow wiring/clearance guidance in the manual.
Verify breaker/circuit capacity for your AC source; enforce limits through CAN where required.
