High Voltage PTC Heater For Enhanced Heating Capacity In Electric Construction Machinery DC 250-870V

Specification:

Introduction

In an effort to save more costs, major manufacturers have impacted driver comfort. Many public transportation departments are increasingly interested in adopting zero-emission electric buses. Given the benefits of electric vehicles, this is not surprising. However, this shift also brings a series of challenges, with battery range being the most important consideration. In cold winters, the vehicle's heater system is the largest power load on the bus, accounting for 20-30% of total energy consumption.

To address this challenge, EVLINK offers a new high-voltage water heater technology with energy-efficient heating capabilities that can reduce the load on the battery, lower the power consumption of electric vehicles, increase the driving range of buses, and save maintenance costs without affecting passenger comfort.

Understanding the EVLINK High-Voltage Water Heater

The EVLINK high-voltage water heater is an advanced built-in PTC and integrated unit heater designed for heating the coolant in the water circuit of zero-emission electric buses. This heater operates on direct current (DC) and is particularly suitable for large electric transportation. It consists of multiple PTC heating elements and has been rigorously tested to automotive standards to ensure that the EVLINK high-voltage water heater meets the highest safety requirements.

Key Features of the EVLINK High-Voltage Water Heater

Power and Voltage Capability

• Power Output: The high-voltage water heater provides up to 20kW of power output. This powerful performance ensures fast and efficient heating of the water circuit, which is crucial for maintaining optimal operation of specialized vehicles.
• Voltage Range: The heater is designed to operate within a wide voltage range of 450 - 850V DC, with a boost range up to 950V DC. This voltage flexibility allows it to integrate into various vehicle systems, meeting different voltage requirements and ensuring compatibility across a wide range of zero-emission electric commercial vehicle applications.

Integrated Control System

• CAN Control Module: The heater is equipped with an integrated CAN2.0 control module, allowing precise and independent control of the heating elements. EVLINK provides the CAN2.0 communication protocol and can customize the CAN protocol to meet customer control needs, also offering DBC files.
• Temperature Sensor Controller: The heater is internally equipped with an integrated temperature sensor controller, ensuring the high-voltage water heater maintains the water circuit at the required temperature. This feature not only improves the efficiency of the heating system but also enhances the safety and reliability of vehicle operation by preventing overheating and maintaining optimal performance.
