As the penetration rate of new energy vehicles continues to rise, the construction of charging stations is entering a boom period; however, the industry remains unable to avoid a key challenge: a single misstep in selecting charging points can lead to losses at every turn.Over 60% of charging station operators have fallen into this selection trap: equipment purchased with a budget of millions proves incompatible with new models featuring 800V high-voltage platforms, turning fast charging into slow charging and driving away customers; fixed-power stations cannot be dynamically scheduled, resulting in charging failures during peak hours and idle power consumption during off-peak hours, with power utilisation rates below 50%; outdoor equipment suffers frequent breakdowns, keeping maintenance costs high;blindly installing too many individual stations has led to initial investment overruns of 30%, with payback periods stretched indefinitely. The root cause of the vast majority of these pitfalls lies in selection processes that focus solely on ‘rated power’, whilst neglecting core metrics such as constant power ranges, environmental adaptability and operational maintenance capabilities, ultimately resulting in a severe mismatch between equipment and operational scenarios.

The root cause of profitability challenges at charging stations lies in misaligned equipment selection

The current profitability crisis in the charging industry is by no means due to insufficient market demand, but rather because mismatched equipment selection at the front end has effectively capped potential profits. On the one hand, equipment is poorly suited to vehicle models; as 800V high-voltage vehicles become more widespread, older fixed charging points cannot deliver full power output, failing to retain core users. On the other hand, power utilisation efficiency is low; fixed charging points cannot be dynamically scheduled, so equipment utilisation remains low whilst fixed costs for site space and electricity continue to accrue.Furthermore, inadequate environmental adaptability leads to high failure rates, with frequent downtime resulting in direct revenue losses; equipment selected without long-term planning depreciates rapidly, ultimately trapping operators in a vicious cycle where ‘the more they invest, the greater their losses’. The fundamental reason why the vast majority of operators fall into this trap is that they have chosen the wrong evaluation criteria, treating the unit purchase price as the primary basis whilst overlooking the fact that, as a means of production, a charging桩’s core value lies in its profitability throughout its entire lifecycle.A truly scientific selection process is never simply about choosing the cheapest option; rather, it must be anchored to five core criteria: suitability for the specific site’s scale; compatibility with current and future vehicle models; stable operation across all geographical environments; comprehensive safety protection; and low-cost intelligent operation and maintenance capabilities. These five criteria form the core design logic behind the Nengyi Xingnengshan series of charging equipment.

Breakthrough Solution: Nengyi Xing Nengshan Series All-Scenario Charging Equipment and Selection Guide

The Nengyi Xing Nengshan series focuses on two main product lines: integrated chargers and split-type chargers. The integrated chargers comply with both Chinese and European standards, whilst the split-type chargers comply with Chinese standards. They feature IP54 protection and multiple electrical safety safeguards, support remote intelligent operation and maintenance, and cover all station deployment requirements.

The European-standard integrated DC charging unit is specifically designed for international scenarios, with a rated power of 120–360 kW, an output voltage of 150–1000 VDC,a wide constant-power range of 300–1000 VDC, a high current output of 500 A, and stable operation between -30°C and 50°C. Utilising refrigerant-based circulation cooling and a modular design that supports one-touch charging and remote management, these units are perfectly suited to cross-border logistics and charging scenarios for European-specification vehicles.

The Chinese Standard integrated DC charger is the main model for domestic commercial charging stations. It is suitable for fast charging of electric vehicles and is ideal for installation at EV charging and battery swap stations, parking spaces and similar locations. With a rated power of 320–480 kW and an output voltage of 200–1000 VDC,with a constant power range of 300–1000 VDC and a maximum output current of 600 A. The standard version operates in a wide temperature range of -20°C to 55°C, whilst the arctic version operates from -40°C to 55°C. Featuring forced air cooling, it is easy to install and commission, and is compatible with over 99% of domestic passenger and commercial vehicle models.

Split-type chargers are specifically designed for medium to large-scale charging stations, with rated power of 600/720/960 kW. They offer fully flexible power allocation in 40 kW increments, with a maximum single-channel output of 300 kW and 300 A.Peak efficiency reaches 96%, supporting both slow and fast charging modes. Intelligent air cooling combined with remote load balancing boosts power utilisation to over 90%, making it the core choice for large-scale charging stations seeking to reduce costs and improve efficiency.

The Nengshan series offers precise configuration options for different scenarios: for residential communities and small community charging points, the national standard integrated chargers provide flexible deployment and simple maintenance;For motorway and national highway fast-charging stations, combine national standard integrated chargers with split-type chargers to maintain charging speeds during peak hours and eliminate idle power consumption during off-peak periods; for logistics parks and commercial vehicle fleets, opt for split-type chargers to ensure uninterrupted centralised charging whilst reducing initial investment by 30%; for cross-border and international stations, select European standard integrated chargers to ensure compliance and compatibility with European vehicle models.

Reducing costs and improving efficiency at source, reshaping the station profit model

Through comprehensive product coverage and precise selection, the Nengyi Xingneng and Nengshan series address the industry’s selection challenges at their root, delivering quantifiable core value to operators: a wide constant-power range design resolves vehicle compatibility issues, boosting station ROI by over 20%; a full product range covers all scenarios, eliminating the need to coordinate with multiple suppliers and reducing communication and maintenance costs by 50%;multi-layered protection and remote intelligent maintenance reduce annual station failure rates by 60% and maintenance costs by 40%; split-type chargers boost power utilisation to over 90%, saving 30% on initial investment and shortening the station’s payback period by more than 25%. Competition in the new energy charging industry has long moved beyond a race for equipment numbers into an era of refined operations.

In the future, only charging solutions that align with specific scenario requirements and achieve cost reductions across the entire lifecycle will be able to establish a firm foothold in the industry. The Nengyi Xingnengshan series has always been guided by the core philosophy of ‘making charging smarter’, providing all-scenario, full-lifecycle charging solutions. From selection and planning to installation and maintenance, we support operators throughout the entire chain to build high-return, highly stable charging stations.
