EV Charger Manufacturers Warn You to Beware of Traps

TKT is one of China’s leading EV charger manufacturers, focusing on overseas markets. We have been deeply rooted in the overseas expansion sector for a full 10 years. We facilitate business connections through global industry Google, exhibitions, LinkedIn, and WhatsApp. Our team has connected with over 500 EV charging station investors, fleet operators, and commercial real estate clients. They are from Southeast Asia, the Middle East, Europe, etc.

Our team not only provides pre-sales consultation but also maintains communication with past clients to understand their operational status. I have personally witnessed many industry players enter the market with high expectations for the new energy vehicle sector, from confidently selecting sites and building, to struggling through difficulties, to projects stalling or even shutting down. Having been deeply involved in this industry for many years, I’ve always believed that most investors aren’t necessarily lacking in judgment. So what is it? I believe it’s because they’ve adopted “idealized” estimation models.

The Trap: Top-Spec Equipment

In 2022, a commercial real estate client from the Middle East approached us with plans to build a “benchmark” EV charging station in their capital city’s prime commercial district. They intended to purchase twenty 320kW high-speed DC chargers in one go, insisting on “going for the best” to avoid the need for future upgrades.

After evaluating the project based on local market data, our pre-sales technical team offered a completely different recommendation. On one hand, the mainstream passenger vehicles available locally generally had BMS fast-charging capacities in the 120–180kW range, with fewer than 5% of models capable of supporting 320kW charging. On the other hand, the site’s grid connection capacity was insufficient to support twenty 320kW chargers. Applying for a grid capacity expansion would entail high costs and a lengthy approval process.

We suggested installing five 120kW and five 180kW DC chargers initially, aligning with current vehicle capabilities and grid conditions. And upgrading gradually as vehicle models evolved and grid capacity expanded. The client declined our advice and insisted on purchasing the top-spec equipment as originally planned.

Subsequently, the station’s average utilization rate remained below 7%. When combined with various annual fees, the projected payback period exceeded 25 years. Factoring in the EV chargers’ service life, the project lost any possibility of profitability.

EV Charger Manufacturer Reminder: When selecting EV charging infrastructure, “higher specifications” are not necessarily better; the optimal choice is one that aligns with current market realities.

The Trap: Low-Cost Sites Often Hide Fatal Flaws

In 2023, a business owner in Southeast Asia leased a plot of undeveloped land next to a suburban industrial park. The annual rent was under $10,000 USD, nearly 60% cheaper than similar plots along the main road. He quickly built a fast-charging station, targeting local electric freight trucks. However, once the station was ready for operation, a critical problem emerged. The access road was only 4 meters wide, making it impossible for 12-meter semi-trailers to turn in. Drivers who tried it once never returned, preferring to detour an extra 5 kilometers to charging stations operated by other brands. Price cuts and promotions proved useless. Attempts to sublease the site found no takers.

EV Car Charger Manufacturers Reminder: Site selection is the make-or-break factor; rental cost is always the least important metric. Can large vehicles enter and make U-turns? Is there space for queuing? Are there height restrictions? What are the parking time limits? These are the life-or-death issues for commercial vehicle charging stations—far more critical than the rent.

Here is another story:

In 2025, a business owner in Uttar Pradesh, India, quietly replaced the originally specified 185mm² copper core cable with a 150mm² cable. He felt that saving 200,000 rupees (more than $2,000) in material costs was worthwhile. After two months of operation, system monitoring revealed excessively high line losses, more than double the normal level. A detailed calculation showed that the additional electricity costs over a year would exceed 1.5 million rupees ($15,000).

To switch back to the 185mm² cables, he had to break up the pavement, halt operations, and carry out a new installation. Spending hundreds of thousands of rupees in the process. Ultimately, the attempt to save 200,000 rupees resulted in spending even more to rectify the mistake.

EV Charger Manufacturers Reminder: Cables are the lifeblood of EV chargers; a 185mm² specification must never be downgraded to 150mm². Whether in the sweltering heat of India or the freezing cold of Northern Europe, skimping on cable specifications is akin to planting a ticking time bomb.

Different countries have strict, mandatory compliance standards for power distribution infrastructure. Substandard cable specifications lead to more than just high line losses; they result in failure to pass grid-connection inspections, rendering the facility inoperable.

Note: TKT entered the Indian market early on and is one of the top EV charger manufacturing companies in India.

The Trap: Subsidy Dependency

In 2023, a German business owner spotted an opportunity in local government subsidies for commercial charging infrastructure, which could cover up to 40% of investment costs. Confident of a return on investment within roughly two years of receiving the subsidy, he proceeded to build the station. However, after submitting his application, he was forced to revise and resubmit materials five times and faced a 14-month approval queue. Ultimately, he was informed that the subsidy budget was exhausted and the next round of policy was undecided.

With the station built but the subsidy unobtained, the payback period based solely on operational revenue stretched to 6 years. He later told me that had he based his financial projections on receiving “zero subsidy” from the start, he never would have built the station at that location.

EV Charger Manufacturers Reminder: Subsidies come with three major uncertainties. Policies can change at any time, approval processes are slow, and funding pools are capped. When making investment decisions, calculate the numbers assuming “zero subsidy” first; only proceed if the project is profitable on its own merits. Treat any subsidy as a bonus.

The Trap: Payment Issues

In 2023, a client in France built an EV charging station that boasted excellent aesthetics, equipment power, and site selection. However, during the first three months, the average daily charging volume was only one-third of what had been projected. An investigation revealed the reason. Local commercial vehicle drivers were accustomed to using mainstream French roaming cards and local apps for payment, whereas the station’s payment system was overly complex. Consequently, most drivers found the process too troublesome and simply left.

EV Charger Manufacturers Reminder: Every country has its own preferred payment methods and localized charging networks. We recommend that clients purchase hardware and software separately. Importing affordable hardware from China while selecting a local charging software provider. Joining the corresponding charging network can actually boost the station’s visibility and attract nearby users who already utilize that app.

The Trap: Grid Capacity

In 2023, a European logistics park owner selected a plot of industrial land with very low rent on the city outskirts. He signed a five-year lease and even began construction work before formally applying to the local utility company for a grid connection. When he finally applied for power distribution, he was informed that the area’s capacity was already saturated. Expanding capacity would require waiting for the next round of infrastructure planning, a process estimated to take over 14 months.

He had already paid a year’s rent and deposits for construction. Continuing meant the financial and time costs of expanding capacity would far exceed his budget. Abandoning the project meant his initial investment would go down the drain. Ultimately, he had no choice but to cut his losses and withdraw.

EV Charger Manufacturers Reminder: Grid capacity expansion can involve municipal planning and transformer procurement lead times; delays of six months to a year are common. Before building a facility, always secure a written commitment regarding power supply and an estimated timeline from the utility company to avoid having the site sit idle.

Summary of EV Charger Manufacturers

After a decade of deep engagement in overseas markets, I have witnessed the successes and failures of numerous charging station projects. I offer this sincere advice to all investors: beyond visible expenses like procurement and rent, you must thoroughly understand the hidden costs involved from the outset.

Operators who truly succeed in the charging market share a common habit: they always base their projections on a worst-case scenario.

1 Calculate equipment utilization using a conservative rate of 10%–15%. Only consider expansion or upgrades if the project is profitable at that level.

2. Budget for power distribution and cabling based on the highest local compliance standards. Never attempt to control costs by skimping on core components.

3. Clarify traffic patterns and power capacity planning in advance to eliminate risks before any investment is made.

The market opportunities in new energy charging are real, but profitability is never achieved through bandwagon-jumping or luck; it comes from respecting the local market and making rational, meticulous financial calculations.

As an EV charger manufacturing company in India and China, we provide not only compliant charging equipment across the full power range but also comprehensive support—drawing on our project implementation experience—covering everything from grid assessment and site selection analysis to tailored solution design.
