FAQ

Q: How to choose the right PTC water heater?
A: Please provide the following parameters to help with selection:

· Application scenario (bus / heavy-duty truck)

· Intended use (battery heating, cabin heating, regenerative braking energy recovery)

· Operating conditions

· Operating voltage range

· Rated voltage and power

· Battery type and capacity

· Target outlet water temperature

· Ambient operating temperature

· Coolant flow rate

· Installation space

Q: How does a PTC water heater work?
A: The PTC heater works by passing electric current through PTC ceramic material. The material’s resistance increases as temperature rises, automatically adjusting the heating power to maintain a constant temperature.

Q: Which vehicle types is it suitable for?
A: Suitable for most electric buses, electric trucks, and electric construction machinery (excavators, loaders, etc.).

Q: How does it perform in low-temperature environments?
A: PTC heaters remain stable in low-temperature conditions, making them ideal for electric vehicles in cold regions.

Q: What are the core advantages of EVLINK PTC water heaters?
A: High reliability, fast and uniform heating, patented thermal expansion control, moisture protection, and exceptional performance under extreme conditions.

Q: Is customized development supported?
A: Yes. Common customization options include:

· Power rating (3 kW – 35 kW)

· Voltage platform (400 V – 800 V)

· Communication protocol (CAN / EN enable)

· Mounting bracket design and dimensions

· High-voltage and low-voltage connectors

Q: Is OEM/ODM customization available?
A: Yes. Options include:

· Power and voltage customization

· Connector types

· Communication protocols (CAN, etc.)

· Appearance and mounting structure

Q: What is the lead time?
A: Minimum order quantity: 1 unit. Sample delivery within 7 days. Agile development ensures rapid response to changing requirements.

Q: Are certifications available?
A: The product meets automotive-grade standards and can provide certifications such as CE, ISO, and E-Mark.

Q: Are sample tests supported?
A: Yes. Samples can be provided for performance verification and vehicle integration testing.

1. It is designed to integrate seamlessly into existing high-voltage systems, minimizing disruptions and downtime.
2. The heater is engineered for reliable and consistent heating performance, ensuring the smooth operation of high-voltage equipment.

 Ø Superior Water Resistance

Navigating through muddy terrains or enduring prolonged periods in wet rainy conditions and high temperatures, the HVCH QA01 series showcases superior water resistance. Its IP67 water and dustproof certifications are a testament to the product's long-term reliability and durability.

Ø Stepless Performance Regulation

This high-voltage coolant heater offers a stepless regulation of performance, whether it's by manipulating the water outlet temperature or constraining the peak heat output or power usage. Validated over three years of practical applications, this product has been integrated into thousands of vehicles, earning accolades from satisfied customers.

 Ø Reliable Dual Self-Protection System

The dual protection system, embracing both mechanical and electronic safeguards, acts proactively to shut down the module in instances of short circuits, overloads, or over-temperature conditions. Moreover, high voltage relays and current fuses have been incorporated in the high-voltage circuit, providing an added layer of safety.

Ø Complete Separation of Water and Electricity

We have skillfully resolved the conflicting demands of heat transfer efficiency and the insulation prerequisites of DC 3500 V, achieving a complete separation of water and electricity. This technological innovation has facilitated the mass production and deployment of our 870V (nominal voltage) products in heavy dump trucks since 2021.

 Application Scenarios

To ensure a secure journey even in challenging climate conditions, vehicles need to be ready for operation right from the start. A robust power range of 15 to 25 kW can cater to the heating, defrosting, and battery heating needs of large vehicles. Users can adjust the power according to the demands, controlling the power consumption. We also offer customized services, making adjustments as per customer requirements, like voltage, power, etc.
