QB01-Series (15-35kW)Nominal Voltage DC 870V High Voltage Coolant Heater With Relay and Current Fuse

1. It is designed to be environmentally friendly, with low emissions and energy-efficient operation.
2. The heater is equipped with built-in diagnostics and self-monitoring capabilities, allowing for quick and accurate troubleshooting.
3. It can be easily integrated into existing EV battery systems without major modifications or disruptions.

HVCH QB01 Series is a model specially designed for the application of DC 870V or 35KW . Compared with QA Series, QB has been improved in the capacity of withstand voltage and the over-current ability,for example in relays, fuse, IGBT, connectors and other parts. QB01 has been applied in many vihecles with nominal voltage of DC 870V since 2021.

HVCH QB01-Series could quickly, consistently,powerfully and reliably heat the vehicle interior. The compact device ensures a constantly high heat output of 15kW-35kW and allows for flexible use in a power range of 350 to 1100 Volts. HVCH QB01-Series features infinitely variable heat output control by means of an integral control unit. This takes place either by regulating the water outlet temperature or by limiting the maximum heat output or power consumption. Furthermore, it is CAN-capable and transmits key operating data to the vehicle system using an intelligent diagnostic function.

Specification:

Product Features:

Ø Excellent Water Resistance.

During the actual operation, muddy roads and wet rainy days and long playing in high temperature, all require our high voltage coolant heater excellent waterproof performance.IP 67 Water and dust proof reports can be provided.

Ø Stepless Regulate Performance.

This takes place either by regulating the water outlet temperature or by limiting the maximum heat output or power consumption.Our High Voltage coolant heater has been equipted in thousands of vehicles for three years ,the good quality has been accecpted by the custmers.

Ø Reliable Dual Self-Protection System

Dual protection system includes mechanical protection device and electronic protection, which acts to shut the module down in reaction to a short circuit, overload, or over-temperature condition. In addition, We add the high voltage relay and current fuse in the high voltage circuit.

Ø Completely Separation of Water and Electricity

Water and electricity is completely separated.Different from other manufacturers,we solve perfectly the contradiction between the heat transmission efficiency with the Insulation requirement of DC 3500 V.Benefits from this technical improvement, our 870V (nominal voltage) products have been mass produced and used in heavy dump trucks in 2021.

Ø PTC thermistor heater with self - controlled constant temperature.

PTC water coolant heater come with all advantages of the PTC heating technology. Thanks to the PTC effect, the heating elements dynamically adjust their power without exceeding a maximum temperature. High operational reliability and energy efficiency without any additional switching elements.
