With the rapid popularization of electric vehicles, long-distance travel has become one of the most frequent usage scenarios. Currently, the limited number of motorway EV charging infrastructure is a factor restricting the development of the electric vehicle industry. Unlike home charging and urban public charging, motorway EV charging has much stricter requirements for charging efficiency and stability. Only high-performance charging equipment can meet the needs of electric vehicle users for quickly replenishing energy during long-distance driving.
Motorway EV Charging, or highway electric vehicle charging, refers to a charging infrastructure system deployed at highway service areas, interchanges, gas stations, and other nodes in the highway network, specifically designed to provide charging services for long-distance travel of new energy vehicles. It is an important sub-segment of public charging.
It differs from home charging and urban public charging in that it is highly suitable for the short dwell times of vehicles, and is a core component in addressing the range anxiety of new energy vehicle owners on long journeys and improving the nationwide charging network.
The core reasons are concentrated in three points, which are also determined by the rigid demands of highway travel:
1. Short Stop Time: New energy vehicle owners typically only stay in highway service areas for 10-30 minutes, such as restroom breaks, rest, or meals. AC slow charging can only add about 0.5 kilometers of range per minute, which is almost ineffective for short stops. DC fast charging, especially the TKT 320kW, can add 20 kilometers of range per minute, replenishing 80% of the battery in a short time.
2. Improved Station Operation Efficiency: During holidays and peak hours, highway service areas experience a surge of charging vehicles. AC slow charging takes a long time per parking space, easily causing congestion and long queues. DC fast charging has extremely high turnover efficiency, requiring only 10-20 minutes to fully charge a vehicle, maximizing the use of limited parking resources in service areas.
3. Coverage of All Vehicle Types: The highway network includes not only passenger cars but also commercial vehicles such as electric trucks and electric tour buses. These vehicles have large battery capacities and urgent charging needs, which AC slow charging cannot meet for long-distance operation.
The value of AC slow charging on highways: It is only suitable for users who rest and stay overnight at highway service areas.
As a designated supplier for Fortune 500 companies such as BYD and Tata Motors, TKT integrates its technological advantages in the charging field into every detail of highway electric vehicle charging equipment. With high-power fast charging, durability, and customized services, TKT possesses core market competitiveness, fully meeting the operational needs of highway charging scenarios.
TKT’s dedicated DC fast charging piles for highways boast a maximum output power of 320kW, compatible with mainstream electric vehicle charging protocols on the market. It can achieve a charging effect of “adding 200 kilometers of range in 10 minutes” for electric vehicles, perfectly addressing the core need of highway users for rapid energy replenishment.
This series of charging equipment adopts innovative power module technology, resulting in high energy conversion efficiency and low standby power consumption. This not only improves charging efficiency but also reduces energy loss at charging stations, effectively lowering the operating costs for highway charging infrastructure operators.
During peak charging periods such as holidays, the system automatically allocates power resources based on the number of vehicles charging and equipment load, preventing grid overload caused by multiple devices charging at high power simultaneously and ensuring the stable operation of the entire highway charging station. Simultaneously, the system supports remote operation and maintenance, allowing after-sales personnel to perform remote fault diagnosis and parameter adjustments without on-site operation, significantly reducing maintenance costs and improving equipment utilization.
Highway charging equipment is exposed to the elements for extended periods, enduring extreme weather conditions such as high temperatures, rain, snow, and strong winds, as well as complex operating conditions such as dust and vehicle vibration. TKT’s highway electric vehicle charging equipment adheres to high industrial-grade design standards, using high-quality raw materials and patented structural designs, possessing characteristics such as rainproof, dustproof, lightning protection, and resistance to high and low temperatures.
TKT boasts a professional R&D team composed of several senior engineers with extensive experience in highway charging infrastructure projects. The company can provide customized solutions based on the characteristics of highway areas, power grid conditions, charging flow scale and user groups in different countries and regions.
In the Indian market, TKT has partnered with leading local company Olectra to build a high-speed charging network connecting major cities such as Mumbai and Delhi. This network supports the operation of electric buses and passenger vehicles, effectively promoting the electrification transformation of intercity transportation in India.
To date, TKT’s highway electric vehicle charging equipment has been sold to 85 countries and regions worldwide, and several benchmark highway charging projects have been completed. Its high efficiency, stability, and reliability have earned high recognition from global customers.
As a leading electric vehicle charging equipment manufacturer in China, TKT, leveraging over a decade of technological accumulation, a global market presence, and innovative R&D capabilities, has developed a 320kW motorway EV charging solution. With its high-power fast charging, intelligent management, and stability, TKT’s charging equipment has been widely deployed in highway service areas across multiple regions globally.
Each TKT charging device is manufactured in a modern production base exceeding 8200㎡ and undergoes multiple rigorous quality inspections before leaving the factory. This ensures extremely high structural stability and lifespan, effectively reducing the failure rate of highway charging equipment during long-term outdoor operation.
