Heavy Equipment BTMS

Heavy Equipment BTMS Overview

Heavy equipment typically refers to construction machinery and mining equipment, which operate in harsh environments such as high temperatures, high vibration, and high dust levels. The electric heavy equipment BTMS (Battery Thermal Management System) is a specialized temperature control system that cools and heats the power batteries in these devices. Batteries operating within the appropriate temperature range can achieve their maximum performance, extend their lifespan, and prevent thermal runaway in heavy equipment, making it safer.

Batteries in electric heavy equipment typically have capacities ranging from 300 to 600 kWh, or even 700 kWh. These batteries experience higher instantaneous charge and discharge currents, generating more heat and placing more stringent heat dissipation requirements. Therefore, the heavy equipment BTMS requires a robust heat dissipation design to withstand extreme temperatures. To meet these demands, the battery cooling system must utilize liquid cooling, which is currently the most mature and economical battery cooling method.

Challenges of Heavy Equipment BTMS in Extreme Environments

1. High Temperature: Battery temperatures can soar above 85°C (e.g., in desert mining areas) during continuous exposure to sunlight or high-load operation.

2. High Vibration and Shock: When operating or traveling on rough terrain, construction machinery experiences vibrations up to 20-50Hz, making traditional liquid cooling pipes susceptible to loosening or leakage.

3. High Dust and Corrosive Environments: Mine dust can easily clog heat dissipation channels, and salt spray corrosion (e.g., in coastal operations) can corrode metal components, degrading insulation performance.

4. Instantaneous High-Power Charging and Discharging: When electric mining trucks climb slopes or start under heavy load, instantaneous currents can reach hundreds of amperes, generating tens of kilowatts of heat from the batteries. Traditional battery air cooling systems struggle to meet these requirements.

TKT Heavy Equipment BTMS Cooperation Projects

TKT was founded in 1998. We possess extensive battery thermal management system design experience and manufacturing capabilities. In 2018, we partnered with TATA Motors, a Fortune 500 company, to develop a custom BTMS. After undergoing multiple rounds of rigorous testing, our product received recognition and praise. Shortly thereafter, we entered into a second collaboration with them on a BTMS for electric trucks.
