AGV wireless charging mode features
GV wireless charging mode has the following features:
High security
* electrical isolation : Wireless charging technology enables electrical isolation between the charging terminal and the AGV energy storage system, fundamentally eliminating safety hazards caused by poor plug contact, plugging damage and other issues in the direct plug charging method, such as sparks, leakage, etc. It is especially suitable for harsh environments such as low-temperature condensation, moisture, flammability and explosion.
* No exposed conductive contacts : The charging contacts are abandoned, and no conductive contacts are exposed on the charger and electrical device, further reducing safety risks such as electric shock and short circuit.
Charging is convenient and efficient
* Charge as soon as you come, stop as soon as you go : AGV does not need manual operation to plug and unplug the charging plug like contact charging, nor does it need to accurately align the charging position. As long as it enters the charging area or is close to the charging device, it can automatically start charging and automatically stop after charging is completed, saving dedicated charging time and improving production efficiency.
* Support online charging : Because of its non-contact wear and high degree of intelligence, it is very suitable for online charging. AGV can use the gap time during the work process to charge independently, such as loading and unloading, when turning and decelerating, etc., without stopping work for long-term charging, reducing the cost of backup batteries and reducing operating costs.
Adaptable
* Good environmental adaptability : The wireless charging module has good waterproof, dustproof, anti-corrosion and other capabilities, and can operate stably in various complex and harsh environments, such as industrial workshops, warehouses, logistics centers and other places.
* Rechargeable during exercise/stationary use : Some advanced wireless charging technologies can not only charge the AGV when it is stopped, but also achieve dynamic charging when the AGV is running at low speed. It can even install charging rails on the ground to allow the AGV to charge while working, which greatly improves the efficiency and flexibility of the AGV.
High degree of intelligence
* Automatic charging control : The AGV can automatically drive to the charging area for charging according to its own power status, and the charging process can be fully automated without manual intervention, reducing labor costs and labor intensity.
* Charging parameters are adjustable : Charging parameters, such as charging power, charging time, etc., can be automatically adjusted through the intelligent control system based on the AGV's different battery types, capacities, and actual power requirements to optimize charging and extend battery life.
Low maintenance cost
* No contact wear : Compared with contact charging, wireless charging does not have the problem of charging contact wear, reducing equipment replacement and maintenance costs caused by contact wear.
* Low failure rate : The structure of the wireless charging system is relatively simple, without complex mechanical moving parts and easily damaged electrical connections. The failure rate is low, which reduces the maintenance time and cost of the equipment.
Good flexibility
* Flexible charging point settings : In usage scenarios such as factories or warehouses, you only need to set up a number of charging points at suitable locations. The AGV car can flexibly select charging points for charging based on task arrangements and power conditions, without the need for a fixed charging area.
* removable charging : Some wireless charging systems also support mobile charging. For example, by installing a wireless charging module on the AGV, it can move and charge freely between different charging areas or devices, further improving the flexibility and efficiency of charging.
Transmission distance is limited but gradually breaks through
* Traditional wireless charging has short distance : Electromagnetic induction charging requires strict alignment of the ground transmitting coil and the vehicle receiving coil, and the transmission distance is usually no more than 3 cm. For example, most AGVs in automobile factories use this method, but the alignment error must be accurately controlled within 5 mm.
* New technology expands transmission distance : Magnetic resonance charging allows the transmitter and receiver coils to resonate at the same frequency, with a transmission distance of up to 10 cm, and allows a certain angle offset. For example, airport baggage transport AGVs can use this feature to charge stably even when the vehicle body is tilted 15 degrees when passing through a corridor bridge.
