1. Power Battery
LFP (Lithium Iron Phosphate) batteries specifically designed for mining vehicles provide high-power current for vehicle startup and operation. They also enable regenerative braking to recover more energy during deceleration, enhancing overall energy efficiency.
2. Drive Motor
The drive motor propels the vehicle forward and generates electricity during coasting. It reverses for backing up and regenerates power during deceleration, providing auxiliary retarding braking and improving energy conservation.
3. Integrated Controller
This unit consolidates multiple functions: DC-DC conversion, steering motor control, high-voltage power distribution, air compressor control, A/C compressor control, and A/C PTC control. It converts high-voltage power to low-voltage for vehicle systems, controls the steering motor, manages high-voltage system power distribution logic, and regulates the air compressor, A/C compressor, and PTC heater.
4. Motor Controller
The motor controller governs the drive motor's operation. Based on inputs like gear position, throttle, and brake signals, it converts power from the traction battery into the required form for the drive motor. It controls vehicle startup, forward/reverse speed, and torque output, while also facilitating energy regeneration during braking.
5. Vehicle Control Unit (VCU)
Acting as the central nervous system of the vehicle, the VCU coordinates overall vehicle control based on driver inputs and road conditions.
6. Automatic Transmission Control Unit (TCU)
This controller manages transmission operation, enabling gear shifts (including Neutral, 1st, 2nd, 3rd, Reverse) to alter driving force and vehicle speed for forward movement, reversing, parking, and climbing.
7. High-Power Controller
This controller manages all low-voltage electrical devices, distributes the 24V vehicle electrical supply, controls power on/off to devices, and provides short-circuit protection.
8. Battery Management System (BMS)
The BMS serves as the critical link between the onboard traction battery and the electric vehicle. It performs comprehensive battery management to optimize utilization, prevent overcharging and over-discharging, extend battery life, and monitor battery status.
9. Transmission
The transmission facilitates gear selection (Neutral, 1st, 2nd, 3rd, Reverse) and incorporates a power take-off (PTO) for lifting devices.
10. Electric Power Steering Pump (EPS Pump)
Driven by a dedicated motor, the EPS pump supplies hydraulic fluid flow to the steering system, providing the necessary hydraulic power for steering assist. This ensures light, reliable steering and features variable frequency capability to reduce energy consumption.
11. Electric Air Compressor
Utilizing a permanent magnet synchronous motor (PMSM) driving a piston compressor, the electric air compressor generates compressed air for the vehicle's braking system, lifting system, and gear shifting functions.
12. Chiller Unit
This liquid cooling/heating system maintains the traction battery within its optimal operating temperature range. This enhances battery performance and longevity.
Customer Success
