Iwe Unoenzanisa Sei Lead-asidhi Mabhatiri?

The Buckets Effect: Huwandu hwemvura inogona kubata bhaketi zvinoenderana netsvimbo yayo pfupi.

Munzvimbo yemabhatiri, iyo Buckets Effect inoonekwa: Kuita kwebhatiri pack kunoenderana nesero rine yakaderera voltage. Kana voltage balancing yakashata, chiitiko chinoitika chekuti bhatiri razara chaji mushure menguva pfupi yekuchaja.

Maitiro ekugadzirisa sei nyaya yemabhatiri voltage balancing uye kuwedzera hupenyu hwavo?

Maitiro echinyakare: 

Manual periodic inspection kuona mabhatiri ane low voltage uye ega ega kuchaja mabhatiri ane low voltage.

Smart Approach: 

BMS (Battery Management System) ine otomatiki kuenzanisa basa iro rinogona kudzikamisa voltage panguva yekuchaja nekuburitsa.

Kuenzanisa otomatiki kunosanganisira kushanda uye kungoita kuenzanisa.

Active balancing inosanganisira kuchaja-based uye simba-transfer-based balancing.

Active Bancing (Energy-Transfer-Based):

Kuenzanisa kunoitwa nenzira yekusarasikirwa kwekutamisa simba, kureva kuti, simba rinotamiswa kubva kumaseru ane voltage yakakwira kuenda kune ane yakaderera voltage, kuwana chiyero chevoltage yakazara nekurasikirwa kwesimba kushoma; saka, inonziwo kusarasika kuenzanisa.

 

Zvakanakira:  Kurasikirwa kwesimba kushoma, kushanda kwakanyanya, kureba kwenguva, yakakwirira ikozvino, kukurumidza kuita.

Zvakaipa:  Complex circuitry, high cost.

Active Balancing (Kuchaji-Kubva):

Iko kune DC / DC simba module mukati mega yega yekutarisa sero sensor. Munguva yekuchaja yeyangarara, module inochaja sero neiyo yakaderera voltage kuti iwedzere kuchaja kwayo kusvika yasvika pakaiswa voltage balance.

 

Zvazvakanakira:  Kuchaja kwakanangidzirwa kwemaseru asingachaji kana kuita zvishoma.

Zvakaipa:  Mutengo wepamusoro nekuda kwekudiwa kweDC / DC magetsi modules, njodzi yekuwedzeredza (zvinogoneka nekutonga zvisiri izvo), mutengo wepamusoro wekugadzirisa nekuda kwekutadza kukundikana.

Passive Bancing (Kubvisa-Kubva):

Passive balancing inowanzo sanganisira kuburitsa masero emagetsi epamusoro kuburikidza nevanopikisa, kuburitsa simba nenzira yekupisa kuti iwane huwandu hwemagetsi, nekudaro zvichibvumira mamwe maseru nguva yekuchaja panguva yekuchaja.

 

Zvakanakira:  Low discharge ikozvino, yakavimbika tekinoroji, inodhura-inoshanda.

Zvakaipa:  Nguva pfupi yekuburitsa, inononoka kuita.

Muchidimbu, iyo yazvino BMS yemabhatiri e-lead-asidhi kazhinji anotora passive balancing. Mune ramangwana, Dfun ichaunza hybrid balancing, iyo inoyera-high-voltage maseru kuburikidza nekuburitsa uye mashoma-voltage maseru kuburikidza nekuchaja.
