Q&A summary:

1. How many battery strings can Infineon's BMS solution support?

A: A maximum of 63 9012DQUs can be connected in series. Currently, 38 9012DQUs have been tested in series on a real system to meet the needs of a 1500V energy storage system.

2. Can the management of a single battery be realized? Or how many strings of batteries can be managed as the minimum unit?

A: Minimum 4 strings can be measured

3. Does the system have a quality management system certificate?

A: There is no third-party certificate. AFE and PMIC are certified by Infineon's independent laboratory for ASIL D. AURIX TC3xx has SGS ASIL D certificate. Complex driver CDD has a third-party license version. The system needs customers to do ASIL D certification. We can support audit.

4. Which battery balancing solution is used?

A: Passive Balance

5. What is the battery collection module used for?

A: 12 independent 16-bit ADC modules

6. Is there a block diagram?

A: There will be a block diagram introduction later, please pay attention to it.

7. How is the data collected by the acquisition module transmitted to the MCU?

A:UART

8. What is the accuracy of battery power collection?

A: I will introduce it later.

9. For the 400V/800V solution, AFEs also need to be isolated.

A: Yes, the board is isolated by capacitors and the boards are isolated by transformers

10. What is the maximum balancing current? Is an external MOS required?

A:200mA, no external MOS required

11. What are the advantages of Infineon AFE? It seems that the performance of AFEs from different manufacturers is similar.

A: 12-channel independent ADC, balanced without PWM,

12. Can it be applied to photovoltaic energy storage?

A: Yes, some customers are using it.

13. What is the relationship between Pinjia and WPG?

A: Pinjia is a subsidiary of WPG

14. What BMS management chips does Infineon have?

A: Currently only 9012DQU

15. Is there any solution for rail transit?

A: Welcome to communicate after the meeting
