Technical Excellence & Engineering Authority
1. Advanced Thermal & Safety Protection
Reliability in high-voltage systems is achieved through rigorous safety logic. To ensure maximum Trustworthiness, this 2kW charger integrates five major protection layers:
-
Over-temperature Protection: Intelligent thermal management automatically reduces current if internal temperatures exceed 80°C and initiates a protective shutdown at 85°C.
-
Short-circuit Protection: Automated output shutdown in the event of a short circuit, with seamless recovery once the fault is cleared.
-
Battery Reverse-connection Protection: The internal circuit automatically disconnects if the battery is connected incorrectly, preventing hardware damage.
-
Voltage Safeguards: Automated shutdown if input voltage falls below 90V or exceeds 264V.
2. Smart Integration & Control
Designed for modern vehicle architectures, this charger offers intelligent communication and monitoring features:
-
CAN Communication (Optional): Enables real-time data exchange with the Battery Management System (BMS) for optimized charging curves.
-
12V Auxiliary Power (Optional): Features a built-in 12V 5A power supply to support low-voltage vehicle electronics.
-
LED Status Indicators: Integrated LED lighting provides immediate visual feedback on the current charging process.

Frequently Asked Questions (FAQ)
Q: Can this charger operate in wet or dusty environments?
A: Yes. The unit is fully sealed with an IP67 rating, making it ideal for outdoor applications, marine environments, or industrial sites where dust and water exposure are common.
Q: Does it support different battery types?
A: Yes. Through its digital control and optional CAN communication, charging curves can be optimized for various battery chemistries, including Lithium-ion and Lead-acid configurations.
Q: What happens if the power grid voltage is unstable?
A: The charger is designed for global grid stability. It will operate normally between 90V and 264V. If the voltage moves outside this range, the unit will automatically shut down to protect both the charger and the battery.
