Powertrain for an electric motorcycle

Hi Martin,

Please specify the input and output voltage range.

Best Regards,

Feng Ji

Hi Feng JI, 

The battery voltage is 72v nominal (66-84v). 

Hi Martin,

So we can consider the input as 66V~84V and output as 72V/3kW?

Best Regards,

Feng Ji

Absolutely! Feel free to ask me any other questions.

Thank you very much for your attention!

Hi Martin,

i just checked our available reference designs but could not find one which is very close to your requirements.

The LM5170 might be a suitable device which would fit to your input and output voltage range.

For that power range the design for sure need to be a multiphase solution.

Best regards,

Hi Stefan, 

Id like to know if you could propose any other solution to use the regenerative brake to charge the battery. 

Hi Martin,

have you already checked the following resources:

TI Reference Designs Library

and

Hybrid, electric & powertrain systems design resources | TI.com

Maybe there is already something which is close to your requirements.

Best regards,

 Stefan
