Technical Advantages
● High-fidelity battery simulation
- Support multi-chemical system battery cell models such as ternary lithium/lithium iron phosphate
- Accurately simulate complex characteristics such as SOC/SOH estimation, temperature gradient, battery cell aging, etc.
- Customizable parameters to truly reproduce battery pack behavior
● Link closed-loop test
- Covering the complete test chain of charging interaction → charging and discharging management → fault response
- Verify key functions such as balancing control and overvoltage protection
- Support standard tests such as GB/T31467
● Microsecond real-time architecture
- μs-level response accuracy based on FPGA
- Modular design adapts to different battery topologies
- 40MHzPWM acquisition/2MHzDA output to meet high-speed signal processing
Typical Test Scenarios
● 40MHz PWM acquisition channel for inverter IGBT control signal acquisition;
● 2MHz high-speed DA output channel for resolver signal and three-phase current signal simulation;
● While performing high-speed IO signal processing, it meets the real-time simulation requirements of the motor model, and the simulation step can be less than 1us
