Application of dispensing machines in the electrical control system of new energy vehicles

 Dispensing and potting machines are primarily employed in the manufacturing of new energy vehicles within the three-electric systems ( power batteries, drive motors, and electronic control systems ). Through high precision, automation, and intelligent control, they fulfil the industry requirements for new energy vehicle production.  

 

1.What are the “Three Electrics”in New Energy Vehicles?

( 1 ) Battery system   Equivalent to the engine in a petrol vehicle, it serves as the power source. Functioning as an energy storage device, it stores direct current (DC) electricity. This is essential because, unlike trams that operate on overhead lines, vehicles cannot be continuously powered by an external source during operation.

( 2 ) Electric drive system   This functions as the equivalent of a petrol vehicle’s gearbox. The battery supplies power to the motor via the motor controller, and the motor’s rotation propels the vehicle forward. Modern automotive motors predominantly utilise permanent magnet synchronous motors (PMSMs), a type of AC motor. These offer high power output, light weight, compact size, and a wide rotational speed range, making them widely adopted.

( 3 ) Electronic control system   Also termed the intelligent power module, this constitutes the core control unit of an electric vehicle. It directly collects acceleration/deceleration signals, braking signals, and gear position signals via hardwired connections. Through the CAN bus, it gathers battery status information, interprets driver intent, and regulates the drive motor’s operation based on the vehicle’s state to ensure normal driving. Both forward and reverse rotation of the motor are controlled by the motor controller, which also safeguards the motor.

 二、Application of dispensing machines in the electronic control industry

（1）CIPG/FIPG dispensing process for electronic control systems (sealing dispensing)

 

Process description:

‘Sealing’ denotes a continuous adhesive bond. Within new energy vehicle powertrain manufacturing, sealants are typically employed as FIPG (Form-In-Place Gasket) and CIPG (Cure-In-Place Gasket). The adhesive forms a continuous liquid seal between the housing and cover plate, preventing ingress of dust, moisture, and other contaminants that could damage sensitive components or electronic elements. Key application points include the end caps of electric vehicle motors, BMS, OBC, screens, and other automotive electronic enclosures.

 

CIPG characteristics:

Sealing achieved through compression;

Sealed components remain disassemblable;

Automation replaces manual labour for precise dispensing and assembly;

Clamping force adjustable to specifications.

FIPG Characteristics: Achieves sealing through adhesion; simplified process reduces production costs; suitable for diverse structural components; mitigates risks of localised excessive stress.
