Product Description

 

Introduction

In recent years, with increasingly stringent environmental policies and the continuous development of new energy technologies, battery-swapping heavy trucks have gradually gained a foothold in the heavy truck market due to their unique advantages. Compared to traditional diesel heavy trucks, battery-swapping heavy trucks not only have significant environmental benefits but also offer cost savings in long-term operations for enterprises.

The advantages of battery-swapping heavy trucks are mainly reflected in two aspects. Firstly, from an environmental perspective, battery-swapping heavy trucks can significantly reduce exhaust emissions, contributing positively to air quality improvement. This is especially important today, given the frequent occurrences of heavy pollution weather. Secondly, from an economic perspective, although the initial purchase cost of battery-swapping heavy trucks is higher, their operating costs are lower. Over the long term, the total cost is significantly lower than that of diesel heavy trucks.

Safety Precautions

Surge Current Management

  • Using PTC chips with good low-temperature start-up performance to smooth the current curve and reduce surge current.
  • Staggered start-up reduces overall current.

Transient Overvoltage Protection

  • High-voltage power supply filter capacitors and overvoltage protection devices.
  • Selecting 1600V IGBTs to increase breakdown voltage.

High-Temperature Risk Control

  • Combining mechanical temperature control switches with glass-sealed NTC thermistors to ensure safety under high temperatures.

Waterproof Structure

  • Silicone parts combined with stainless steel plates ensure waterproof performance at inlet and outlet pipes.
  • Optimized mounting feet design enhances resistance to bumps and impacts.

Control Logic

Soft Start

  • Grouped start-up, each group controlled by independent IGBTs, with special step-by-step start-up logic to achieve smooth start-up.

PID Regulation

  • Collaborating with customers to debug PID regulation, optimizing energy-saving strategies based on temperature.

No-Load Switching

  • Combining contactors with IGBTs to ensure minimal impact on contactors during switching, preventing adhesion.
