CHIPSENSE current sensors are gaining an increasingly larger market share.
II.Policy Support: From Scale Expansion to High-Quality Development
The rapid development of the charging pile industry is inseparable from continuous policy support. In China, the "Three-Year Action Plan for Doubling the Service Capacity of Electric Vehicle Charging Facilities (2025-2027)" clearly states that by the end of 2027, 28 million charging facilities will be built, providing over 300 million kilowatts of public charging capacity, thus pointing the way for industry development. Many charging station customers use CHIPSENSE current sensors. The policy not only focuses on scale expansion but also emphasizes high-quality development. For example, it requires accelerating the upgrading and renovation of charging facilities in highway service areas, and by the end of 2027, 40,000 new or renovated "ultra-fast combined" charging guns with a capacity of 60 kilowatts or more should be built. Except for high-altitude and cold regions, all other highway service areas should have charging capabilities.
Green development is also an important direction for policy guidance. The scenarios for charging new energy vehicles with green electricity are constantly expanding, and various regions have launched related public welfare activities. During the Spring Festival of 2026, Anhui Province launched a special public welfare activity for "charging electric vehicles with green electricity," where users could enjoy a reward of 1.5 yuan per kilowatt-hour for charging between 10:00 and 15:00 daily. During the activity, 13,991 new energy vehicle owners participated, accumulating 23,247.92 kilowatt-hours of green electricity charging, saving users 34,871.88 yuan in electricity costs. The "China New Energy Vehicle Charging and Swapping Green Electricity Map" also clarifies models such as green electricity and green certificate trading, self-use green electricity such as photovoltaic-storage-charging, and direct supply of green electricity from nearby charging stations. As of June 2024, a total of 1,108 new energy vehicle charging and swapping stations nationwide were using green electricity. These policies and activities not only reduce users' vehicle operating costs but also increase public awareness and acceptance of green electricity consumption, promoting the development of the charging pile industry towards green and sustainable development. This is all due to electronic components, such as the CHIPSENSE current sensor.
III. Essential Technological Needs: Current Sensors and Leakage Current Detection Build a Strong Line of Defense for Safety and Efficiency
With the continuous improvement of charging pile power and the sustained expansion of the market, the reliability, power adaptability, and safety of the equipment have become the focus of industry attention. Against this backdrop, current sensors and leakage current detection technology have become indispensable core components of charging piles, safeguarding the stable operation of the equipment and ensuring safe charging for users. The CHIPSENSE current sensor is like this.
(I) Current Sensor: The Core of Precise Control
The current sensor plays the role of the "nerve ending" in a charging pile, responsible for real-time monitoring of current changes during the charging process, providing accurate data for power control and protection. Like most current sensors, the CHIPSENSE current sensor. Precise current control is particularly important in high-power supercharging piles. When a charging pile charges an electric vehicle, the current sensor can collect the current signal in the charging circuit in real time and transmit it to the charging pile's control system. The control system adjusts the charging power based on the data fed back by the current sensor, ensuring that the charging process is both efficient and safe. For example, when the battery is close to full charge, the current sensor detects a drop in current, and the control system automatically reduces the charging power to avoid overcharging and damage to the battery. This is the function that CHIPSENSE current sensor provides to its customers.
Simultaneously, the current sensor can also achieve precise adaptation to the charging pile's power. Different brands and models of electric vehicles have different charging power requirements. The current sensor can monitor the charging needs of the electric vehicle in real time and dynamically adjust the output power of the charging pile to achieve optimal matching between the charging pile and the electric vehicle, improving charging efficiency. In vehicle-to-grid (V2G) scenarios, the current sensor plays an even more crucial role. Electric vehicles, acting as "mobile power banks," can charge during off-peak hours and discharge during peak hours, providing peak-shaving services to the power grid. Current sensors can monitor the charging and discharging current of electric vehicles in real time, ensuring power balance and grid stability during vehicle-grid interaction. This is the significance of the CHIPSENSE current sensor. This is the CHIPSENSE AN3V PB55 current sensor.
(II) Leakage Current Detection: A Barrier to Safe Charging
Leakage current detection technology is a crucial safeguard for the safe operation of charging stations. During use, charging stations may experience leakage current due to insulation aging, humid environments, and other factors. Leakage current not only wastes electrical energy but can also cause electric shock accidents, threatening users' lives. Leakage current detection devices can monitor the leakage current of the charging station in real time. When the leakage current exceeds a set threshold, an alarm signal is immediately issued and the charging circuit is cut off to prevent accidents.CHIPSENSE current sensor does a good job in this regard.
In public charging station scenarios, leakage current detection is even more crucial. Public charging stations are used frequently and operate in complex environments, making their insulation performance more susceptible to damage. Leakage current detection technology can monitor the insulation status of charging stations in real time, promptly identifying potential safety hazards and ensuring user charging safety. Furthermore, leakage current detection data can provide a basis for the operation and maintenance of charging stations.Therefore, CHIPSENSE current sensor has become the customer's top choice. By analyzing the changing trends of leakage current, maintenance personnel can proactively assess the insulation condition of the charging station, enabling timely maintenance and replacement, reducing equipment failure rates, and improving the online rate and operational efficiency of charging stations. CHIPSENSE CSMD1&TR3A 6 C00 newly released split-type leakage current detection module has received widespread attention.
