Core Technical Framework
Our modular and highly integrated framework comprises five core modules: cell technology, pack integration, BMS, thermal management, and safety protection. Each module is designed for synergy and scalability, enabling flexible customization and future upgrades.
Advanced Cell Technology
The cell is the fundamental energy storage unit, determining energy density, power capability, and safety. AIMRSE selects optimal form factors (prismatic, pouch, cylindrical) and chemistries (high-nickel NMC, LFP, semi-solid-state) based on vehicle requirements. We partner with leading global cell manufacturers and conduct rigorous incoming testing (UN38.3, UL 1642) to ensure consistency, reliability, and safety. For next-generation platforms, we offer cell integration support including characterization, abuse tolerance evaluation, and life modeling to guarantee optimal pairing with the vehicle's duty cycle.
Battery Pack Integration (CTP/CTC)
The battery pack serves as the structural and electrical backbone. AIMRSE leverages advanced cell-to-pack (CTP) and cell-to-chassis (CTC) technologies to maximize system-level energy density by eliminating intermediate modules. Our designs prioritize mechanical rigidity, crashworthiness, and lightweight materials (aluminum alloys, high-strength steel). Using FEA and CFD, we optimize structural performance and thermal uniformity, ensuring IP67/68 sealing and durability against vibration, shock, and intrusion while maintaining high volumetric efficiency.
Intelligent BMS & Functional Safety
As the battery's "brain", our BMS integrates advanced algorithms, automotive-grade MCUs, and ISO 26262 ASIL-C/D development processes. It monitors voltage, current, temperature and computes SOC, SOH, SOP with high accuracy. The BMS manages cell balancing (passive/active), contactor control, and thermal coordination, while providing fast fault detection and predictive maintenance alerts. For 800V architectures, we support galvanically isolated communication, ensuring safe and reliable operation throughout the vehicle's life.
Advanced Thermal Management
Maintaining optimal cell temperature is critical for performance and fast charging. AIMRSE designs custom thermal management systems (liquid cooling/heating plates, dielectric fluid, or refrigerant-based direct cooling) to ensure temperature uniformity within ±2°C across all cells. This enables 4C+ fast charging without overheating and supports cold-climate operation via integrated heaters. Model-based feedforward control minimizes energy consumption and maximizes driving range, seamlessly integrating with the vehicle's thermal loop.
Multi-Level Safety Validation
We implement a multi-level protection framework from material to system level: ceramic-coated separators, flame-retardant electrolytes, CID, venting, thermal barriers, and passive propagation resistance (PPR) designs ensuring no thermal propagation for at least 5 minutes (UN R100). System-level validation includes mechanical, electrical, and thermal abuse testing (crush, overcharge, thermal runaway) to comply with global safety regulations. This comprehensive approach guarantees the highest level of occupant and first responder safety.

We also evaluate regional regulatory and certification needs to establish a solid foundation for the subsequent design.
Feasibility Assessment
We evaluate technical routes, cell availability, integration challenges, and compliance with automotive standards. Multiple architecture alternatives (module count, cooling type, BMS topology) are developed. Through comparative analysis of performance, weight, cost, and close client collaboration, we jointly determine the optimal solution for the program.
Detailed Design
Our engineering team performs comprehensive design of cell arrangement, busbar network, cooling channels, enclosure, HV connectors, and BMS hardware/software.

A complete set of technical documentation including DFMEA, DVP&R, and installation manuals is compiled.
Design Review & Validation
A rigorous review mechanism engages senior experts and the OEM's engineering team to examine design maturity, safety compliance, and manufacturability. Any identified issues prompt immediate optimization through an iterative process. After design freeze, prototype samples are built and subjected to design validation (DV) testing according to jointly agreed DVP&R, including mechanical, environmental, electrical, and abuse tests.
Production & After-Sales Support
We provide end-to-end support including production process validation (PPAP), on-site assembly guidance, and training for OEM manufacturing teams. Our technicians ensure smooth ramp-up and seamless integration into the vehicle assembly line. Long-term, we offer field data analysis, warranty processing, and continuous improvement services based on real-world fleet data.
