All products are developed and customized in accordance with international export standards; they are compatible with the OCPP 1.6J protocol, support Ethernet, Wi-Fi, and 4G connectivity, and feature smart charging capabilities along with dynamic load balancing.
I. Dual-Layer Anti-Corrosion Structure: High Durability for Harsh/Coastal Environments
1. External Enclosure: Constructed from high-quality galvanized steel with a powder-coated finish. The coastal-grade version features a coating thickness of ≥100μm, while the standard version offers ≥60–80μm, providing robust corrosion resistance.
2. Internal Structural Components: Fabricated entirely from aluminum-zinc coated steel to enhance internal corrosion resistance. Finished with a matte, fine-textured powder coating that is scratch- and wear-resistant; minor abrasions remain inconspicuous, making it ideal for dusty, high-usage outdoor environments.
3. UV-Resistant Coating: Protects against sun-induced aging, preventing the enclosure from yellowing or cracking, and ensuring a pristine appearance over long-term use. This reduces total lifecycle maintenance costs and extends the equipment's service life.
II. Components from Internationally Renowned Brands
All core components—including charging modules, MCCB circuit breakers, AC/DC contactors, relays, power supply units, and energy meters—are sourced from globally recognized brands, ensuring stable output, high safety standards, and a long operational lifespan.
III. Intelligent Design
1. Ambient Light Sensor for Automatic Brightness Adjustment: Automatically adjusts screen brightness based on ambient lighting conditions, reducing power consumption, extending display lifespan, and ensuring comfortable viewing day and night.
2. External Meter Display: Facilitates on-site meter reading and operational verification, simplifying maintenance checks and providing clear, transparent energy consumption data.
IV. Optimized Airflow Cooling System
The equipment features customized air intake and exhaust channels, utilizing a dedicated, independent cooling path for each component. This effectively limits internal temperature rise; under rated operating conditions, the internal temperature differential (ΔT) is ≤10°C—significantly better than the >20°C differential typical of standard products. This helps slow component aging, enhances overall system reliability, and extends the service life of core components. V. Remote Operations and Maintenance (O&M) Service Platform
The equipment supports the retrieval and querying of operation logs, as well as remote fault diagnosis. This enables precise identification of fault locations, reducing the need for on-site inspections. Furthermore, the platform supports remote firmware upgrades, which shortens troubleshooting time, minimizes equipment downtime, and enhances overall equipment availability. Currently, these remote capabilities are fully implemented for AC charging piles, while grid compatibility verification is underway for DC charging piles.
VI. Field Validation
Nearly 1,000 TKT charging units have been deployed in the Indian market. Many of these units have delivered cumulative energy outputs reaching hundreds of thousands of kWh. Having undergone rigorous real-world operation across diverse and complex environments, the equipment has demonstrated exceptional stability and availability.
Battery Thermal Management System
The TKT Battery Thermal Management System (BTMS) provides precise, real-time regulation of battery pack temperatures. Through active cooling, heating, and temperature balancing, it mitigates battery degradation, enhances charging safety, and extends battery service life. Featuring a modular design, the system offers flexible integration with various vehicle platforms, meeting the customized development requirements of OEMs. Since 2012, TKT has specialized in the R&D of battery thermal management systems. Its 3kW–10kW models are widely used in electric buses, trucks, marine vessels, and heavy-duty equipment. To date, TKT has provided design and technical support to over 150 leading global automotive manufacturers—including BYD, Tata Motors, and Switch Mobility—offering comprehensive integrated solutions, deep involvement in vehicle design and development, and one-stop OEM services.
1. Safety and Compliance
The system features a patented design and has obtained CE certification (supported by official test reports). It utilizes CAN bus control to prevent damage to the battery pack caused by improper operation and carries an IP67 protection rating. With a high level of internal integration, robust load-bearing capacity, and a lightweight design, the system effectively reduces the load on the vehicle.
2. Thermal Management and Structural Performance
The system utilizes liquid cooling (employing a water-glycol mixture) combined with PTC heating technology. The coolant offers excellent thermal conductivity and antifreeze properties, remaining in a liquid state even at low temperatures while ensuring low power consumption for the pump. The PTC heating component warms the coolant, which then circulates through a water-cooling plate to maintain a uniform temperature across the battery pack. This prevents the battery from becoming too hot or too cold, thereby extending its cycle life.
3. A Reliable, Professional Team
TKT employs a team of 135 engineers—including specialists in design, structural, electrical, testing, EMI/EMC, and after-sales support—possessing comprehensive capabilities for the design, development, testing, and certification of refrigeration equipment and components. Our patented coil structure design offers superior cost-efficiency and performance. A meticulous attention to detail ensures the continuous improvement of our product quality.
Electric bus air conditioning
TKT’s air conditioning systems for battery electric buses are purpose-built for commercial vehicles, such as 6–13 meter city buses and coaches. With a cooling capacity ranging from 16 kW to 42 kW, these systems offer optional heat pump heating and CAN bus control. Suitable for a wide range of electric bus projects globally, TKT serves as an official supplier to major manufacturers, including BYD and the Tata Group. Our units have been rigorously field-tested in the demanding, complex operating conditions of the Indian market; they deliver stable, consistent performance across extreme temperature ranges—from intense heat to severe cold. Combining high energy efficiency and low noise levels with exceptional resistance to heat and corrosion, these systems ensure a comfortable cabin environment while minimizing energy consumption, effectively extending the vehicle's driving range.
I.Unique Design:
We utilize a patented condenser coil structure that achieves a larger heat-dissipation surface area while requiring less material. This design delivers industry-leading heat-exchange efficiency and is recognized as having the highest heat-exchange efficiency among such designs in China. Material Selection:
1. Both the condenser and evaporator coils utilize high-quality internally grooved copper tubing paired with hydrophilic aluminum fins. This configuration offers exceptional corrosion resistance—making it ideal for coastal environments with high salt-mist levels—and ensures a service life of over 10 years, outperforming conventional all-aluminum parallel-flow coils.
2. All air conditioning components, including compressors, are sourced from renowned international brands with proven performance. Each component has undergone at least 8 years of market validation, guaranteeing reliability and excellence. The consistent use of copper tubing and aluminum plates enhances product durability and extends service life. Furthermore, the system features an advanced CAN-bus control architecture and an integrated digital control panel, which results in a lower overall failure rate compared to traditional PLC-based control solutions.
II.Safety and Protection Mechanisms:
The system incorporates additional fuses and high-quality electrical components capable of withstanding high voltages. It also employs a comprehensive suite of protective measures—such as high-pressure and low-pressure safeguards—to ensure robust protection for the air conditioning system.
