Core technologies

1.Lightweight and scalability

CTS systematically optimizes the cell design and electrical component selection. We select the lightest steel/aluminum
alloy and high-strength plastics,battery box and pack structure to reduce the volume and weight of the battery system
combined with CAE structural simulation analysis to ensure structural strength and improve energy density.

CTS uses standardized cells and BMS to build a 12V \ 24V \ 48V \ 72V battery modules. It can need different customer's
requirements by its excellent scalability to shorten the pack design cycle.

2.Thermal Management and Simulation Design

CTS has the capabilities of CFD simulation (Computational Fluid Dynamics) and CAE simulation (Computer Aided
Engineering), and can do thermal management simulation design and structural mechanics simulation design for the
pack system. Air cooling system, liquid heat and liquid cooling system, PI film heating, silica gel film heating are used
in the thermal management design.

3.Test and Verification
CTS has its cooperated battery test laboratory. We will verify the battery DV / PV (design verification/production
verification) stage in the laboratory to verify whether the design / production of the battery pack meets the design
requirements. It includes temperature test, mechanical test, external environment simulation test, electrical safety
test, battery performance test, abuse test and so on.
