Product function description
Description of product structure
Appearance and requirements
The appearance should be clean and tidy, and there should be no dents, obvious scratches, cracks, deformations, burrs, mildew and other defects on the surface. Surface coating should not bubble, crack, fall off; Parts should be fastened without looseness.
Structural dimension/material/weight composition
The main size of the wireless charging module (excluding the mounting foot and connector bulge) : 1637730mm (length width height);Overall size (including mounting feet and connector protrations) : 20613662mm (length width height);
The material, weight and quantity of materials used in the structure are shown in the following table:
On the cover
PC+ABS/TPU material, matched with the lower shell to protect the internal structure of wireless charging.
The lower shell
ADC12 material is used to protect the wireless charging internal structure with the lower cover. It provides the installation frame, heat dissipation of the whole machine, IP protection for PCBA, and completes the coordination with the interior of the vehicle
The shield
Provide support and paste surface for coil and strip separation disk assembly.
Coil with separation plate assembly
Function, material, molding process, performance, MP-A13 coil.
Description of waterproof and dustproof module
The flat upper cover and the lower shell are bonded by silicone structure, and the upper cover and the lower shell contact face to face, which plays a certain dust-proof and water-proof role.
Module installation instructions
After the module is located by four positioning columns on the interior panel, the remaining 11 holes are fastened by screwing in self-tapping screws.

Description of realization method of product software protection
function
Various protection functions and methods implemented by the software are as follows:
- Overvoltage protection: Stop charging when the input voltage of the power supply is greater than the overvoltage threshold set in the software;
- Overvoltage recovery: when the power supply voltage returns to the normal working voltage set in the software from the overvoltage state, restart the wireless charging;
- Undervoltage protection: Stop charging when the input voltage of the power supply is less than the undervoltage threshold set in the software;
- Undervoltage recovery: when the power supply voltage returns to the normal operating voltage set in the software from the undervoltage state, restart the wireless charging;
- Overtemperature protection: When it is detected that the temperature of the temperature sensor on the PCB board is higher than the threshold temperature set in the software, stop charging;
- Overtemperature recovery: when it is detected that the temperature of the temperature sensor on the PCB board is restored to the normal working temperature set in the software, wireless charging can be started again;
- Overcurrent protection: When the power input current or coil output current is detected to be greater than the threshold current set in the software, the wireless charging shall be stopped;
- Overpower protection: When it is detected that the input power of the power supply is greater than the threshold power set in the software, stop the wireless charging;
- FOD (Metal foreign body) detection protection:
The wireless charging Qi standard does not specify the detection of foreign matter on the charging plate.
With the increase of wireless devices compatible with this international standard, the problem of system application security is becoming more and more serious. The purpose of foreign body detection (FOD) is to prevent metal and other objects from being heated near the launching platform and causing personal and property safety.
EU declaration of conformity
Hereby, Hefei Invispower Co.,Ltd declares that the radio equipment Wireless Charging Module (model: PAH-3725200) is in compliance with Directive 2014/53/EU.
FCC statement
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and(2) This device must accept any interference received, including interference that may cause undesired operation.
Any changed or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
FCC RF Radiation Exposure Statement: This equipment complies with FCC RF Radiation exposure limits set forth for an uncontrolled environment. This device and its antenna must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
