Core technologies

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.

BMS and Active Balance

CTS has an experienced BMS development team. Our BMS uses passive balance by default. Active balance can be selected which can modify BMS parameters on site according to the actual application of customers, such as CAN / RS485 communication protocol, threshold parameters such as over / under voltage protection, high current protection, over / under temperature protection.

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.

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.
