The application of EMT products in the new energy automobile industry
New energy vehicles refer to vehicles with advanced technical principles and new structures that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new on-board power units) and integrate advanced technologies in vehicle power control and drive.
Composite power electric vehicle refers to hybrid electric vehicles, including motor drive, in line with automobile road traffic, safety regulations of the car, on-board power source has a variety of vehicles: batteries, fuel cells, solar cells, diesel locomotive generator sets, the current composite power electric vehicles generally refer to internal combustion locomotive generators, plus battery electric vehicles.
Pure electric vehicles refer to vehicles powered by on-board power supply, driven by electric motors, and meeting the requirements of road traffic and safety regulations. Due to its relatively small environmental impact compared to traditional cars, its prospects are widely promising, but the current technology is not yet mature.
Electric drive systems, including electric motors, motor controllers and transmission mechanisms. Some electric vehicles can drive the wheels directly by electric motor.
Water-cooled motor: the power is 25-120KW, mainly NHN, NMN as slot insulation paper
Representative models: Xpeng P7, Wuling MINI, Leap T03, Chery Ice Cream, Changan Benben, etc
Features: The market demand is large, and the price of the whole vehicle is low
Flat wire oil-cooled car motor: the power is more than 100KW, mainly using NPN and pure paper as slot insulation paper, some customers use NHN
Representative models: GAC Aion, Leap C01, Leap C11, Tesla, NIO, and Li all models
Features: high motor technical threshold, large investment in flat wire equipment
Development strategy: AHA instead of NHN, APA instead of NHN
Battery system
Termination tape: PET printing tape, the continuous production line will stop once the tape is broken, and the supply risk is large;
Tabear tape: PI tape is more common, the technical requirements are not high, and the electrolyte test is on the line
PACK tape and all kinds of auxiliary tape: temperature-resistant workbench, strapping, outsourcing and other uses
PET, PC insulating sheet: cylindrical battery upper and lower cover insulation, square battery back adhesive lamination and other uses
Traditional battery pack: complex structure, low capacity, aluminum or fiberglass housing, heavy.
CTC/CTB (battery cell-chassis frame): The industry development trend, the battery cell and the body are integrated, more cells can be installed in the same area to increase the endurance, the use of liquid cold plate and thermal conductive binder to solve the problem of packaging and heat dissipation, has achieved mass production.
Development strategy: PC insulation sheet (about 2.5㎡/set), FR4 or GPO-3 processing parts, mica board tape, busbar film.
