7kW AC charging pile design, application solutions and application scenarios

7kW AC charging pile inputs the household 220v AC power into the onboard charger. The onboard charger converts the AC power into DC power and inputs it into the vehicle battery. This involves a conversion efficiency issue. If the conversion efficiency of the onboard charger is 90%, the power output of the charging pile per hour is 7kW h, and the power input into the battery is 7kW h×0.9=6.3kWh per hour, which is what we usually call 6.3 kWh.

In terms of the core functions of charging piles, the two problems they face are the ability to solve the problem of capacity transfer and the problem of payment:

Efficient energy transfer

7kW AC charging pile adopts advanced AC charging technology and supports single-phase input. Through optimized circuit design and intelligent control strategy, it achieves efficient transfer of grid power to electric vehicles. At 7kW rated power, it can significantly shorten charging time and improve user experience.

Smart payment system

The built-in smart billing module supports multiple payment methods, including mobile payment, card payment, etc., ensuring convenience and transparency of fee settlement. Users can pay according to the actual charging amount, avoiding fee disputes in traditional charging methods.

The following editor will introduce in detail the JSY1077 AC charging pile solution and its technical implementation.

7kW AC charging pile single and double gun version application solution features

This module/equipment is mainly used in 7kW AC charging piles, community shared piles, commercial parking lots, enterprise and institution parking lots, car rentals, operator parking lots, etc. The main features are:

Safety and reliability guarantee

Safety and reliability are driven by technological innovation. The charging pile integrates multiple safety functions such as leakage current monitoring, temperature protection, reverse protection, grounding protection and lightning protection to ensure stable operation in complex and changing charging environments, achieve high-precision monitoring of system parameters, and simplify system design to ensure the safety of users and vehicles.

In particular, the JSY1077 AC charging pile also has input undervoltage protection and input overvoltage protection functions. When the input voltage is lower or higher than the set threshold, the charging pile will automatically alarm and shut down until the voltage returns to normal, effectively preventing equipment damage or safety accidents caused by abnormal voltage.

Technology to prolong relay life

To address the problem of easy sticking of charging pile relays, JSY1077 adopts three patented technologies, including zero-crossing protection, soft start, and automatic compensation of relay action time, to increase the contact life of the relay, reduce the failure rate, and improve the overall reliability and service life of the equipment.

Accurate interactive recognition

The charging pile and the electric vehicle use PWM pulse signals for interactive identification to ensure the smooth charging process. The BMS system on the car accurately determines the upper limit of the power that the charging pile can provide by identifying the pulse width emitted by the charging pile. If the pulse width output is inaccurate, the charging pile will automatically adjust to meet the charging needs of different models of electric vehicles.
