Industry pain point: the charging problem in the sand environment

Photovoltaic power stations are mostly distributed in harsh environments such as deserts, Gobi or plateaus, and face the challenges of strong wind and sand, high temperature difference and ultraviolet radiation all year round. Due to the frequent insertion and removal of traditional wired charging interfaces and the intrusion of sand and dust, it is easy to cause problems such as poor contact and short circuit, which seriously affect the working efficiency of robots. According to statistics, the downtime caused by charging failure of outdoor photovoltaic cleaning robots accounts for 15% and 20% of the total working hours, and the average annual increase in manual maintenance costs is 812,000 yuan.

Taking a 2GW photovoltaic power station in the northwest as an example, its cleaning robot originally used contact charging piles, and dust accumulation led to a 40% reduction in charging efficiency, and a single robot needed to manually clean the charging interface more than 3 times a day. This not only increases the cost of operation and maintenance, but also causes the photovoltaic panel cleaning cycle to be prolonged due to frequent downtime, and the power generation efficiency is significantly lost.

Solution: Luyu Energy IP67 dustproof wireless charging technology

For the special needs of photovoltaic scenes, Luyu Energy has developed an IP67 dustproof wireless charging system, which combines closed magnetic resonance technology and dynamic power regulation function to completely solve the charging problem in the outdoor dust environment.

1. Closed magnetic resonance design, isolation of sand intrusion

The charging transmitting end and the receiving end adopt a fully sealed structure, and the core circuit board is protected by nano coating, reaching IP67 dust and waterproof level (can withstand soaking in a depth of 1 meter for 30 minutes).

The magnetic resonance coupling technology realizes 10cm non-contact charging, avoids the friction loss of physical contact charging, and extends the life of the charging module to more than 10 years in the dust environment.

2. Adaptive power regulation, stable efficiency of more than 85%

Equipped with AI power compensation algorithm developed by Luyu, real-time monitoring of dust cover thickness, temperature and other parameters, dynamic adjustment of output power.

Laboratory tests show that when there is dust accumulation on the surface of the transmitter, the charging efficiency can still be maintained at more than 87% (the efficiency of the traditional scheme is less than 50%).

3. Low maintenance design, reduce manual intervention

The surface of the charging board is dust-free coating, and the dust can be automatically shed by natural wind or robot movement, without manual cleaning.

Support remote monitoring, operation and maintenance personnel can view real-time charging status and fault warning through the background.

Measured case: Xinjiang photovoltaic power station annual province 120,000 maintenance costs

In 2023, Luyu Energy deployed 42 sets of outdoor wireless charging systems for a large photovoltaic power station in Xinjiang, replacing the original contact charging pile. Comparison of measured data:

Failure rate decreased by 90% : charging related failures decreased from 12 per month to 1;

Charging efficiency increased by 35% : single charge time reduced from 2 hours to 1.3 hours;

Annual operation and maintenance cost savings of 120,000 yuan: reduce manual cleaning, parts replacement and power generation losses.

The head of operation and maintenance of the power station said: "The wireless charging module can still run stably after sandstorms, the average daily working time of the robot has increased from 6.5 hours to 8.2 hours, and the cleaning cycle of the photovoltaic panel has been shortened by 30%."

Technical Q&A: 3 questions that users are most concerned about

Q1: Does the dust weather affect the wireless charging distance?

The Luyu module supports 10cm gap charging. Even if the robot's charging position is offset by ±10cm due to the tilt of the terrain, the system can still be automatically aligned by magnetic field calibration.

Q2: How to be compatible with different brands of photovoltaic robots?

Luyu provides standardized communication protocols (supporting CAN/RS485 interface), which has been adapted to 90% of mainstream photovoltaic cleaning robot models on the market, and only needs to ｒｅｐｌａｃｅ the receiver module for old equipment transformation (installation is completed within 1 hour).
