Dị ka otu akụkọ nke National Renewable Energy Laboratory (NREL), na mgbe niile batrị unit ikike na-akwụ ụgwọ, ibu ngụkọta ikike nke ike nchekwa usoro, na ala ndị ọzọ na-akwụ ụgwọ ekenyela onye ọ bụla unit nke ikike. Nke a na-eme ka Sistemụ Nchekwa Ike Batrị (BESS) na-abawanye uru na nnukwu{1}} ngwa nchekwa ike ike, dị ka egosiri na tebụl dị n'okpuru.
Nbibi nke sistemu nchekwa ike batrị lithium{0}ion
Kpọmkwem, egosiri nbibi maka nrụpụta, nrụnye, na ntinye nke BESS (Sistemụ Nchekwa Ike Batrị) na tebụl dị n'okpuru.
Nkesa oke ọnụ ahịa BESS (Table 2-4)
| Parameter BESS | Akpa/ Mkpuchi | Eletriki | Nhazi | Njikwa okpomọkụ | Nchekwa ọkụ | PCS (Inverter) | Igwe batrị |
|---|---|---|---|---|---|---|---|
| 50kW / 2h | 4.3% | 11.3% | 8.7% | 3.4% | - | 7.5% | 64.8% |
| 250kW / 2h | 1.5% | 5.2% | 5.6% | 2.4% | 2.3% | 7.0% | 76.0% |
| 2500kW / 2h | 0.7% | 2.5% | 2.0% | 1.3% | 1.0% | 5.0% | 87.5% |
Na-ewere 250kW / 2h containerized BESS dị ka ihe atụ, batrị ga-aza ihe dị ka 76% nke ngụkọta ọnụ; akpa, onye na-ahụ maka mpaghara, njikwa okpomọkụ, nchebe ọkụ, nkesa ike, na ngwa ndị ọzọ metụtara ya (ọkụ, eriri, wdg) ga-abụ ihe dịka 15.5%; na PCS ga-aza ihe dịka 7%. Agbanyeghị, grid{7} ejikọrọ anaghị etinye n'ime sistemu dị n'elu.
Enwere ike ịhụ na, site n'echiche nke ngwaike na n'ichepụta ụgwọ, dị ka ike na ike nke ike nchekwa usoro na-aga n'ihu na-abawanye, nkezi nke ụgwọ maka ike mgbanwe usoro (PCS) na ndị ọzọ eletriki na structural components ga-ebelata otú ahụ, mgbe nkezi nke batrị na-akwụ ụgwọ ga-anọgide na-abawanye. Ya mere, ịchịkwa ọnụ ahịa batrị ga-enwe mmetụta dị mkpa n'ibelata ọnụ ahịa nchekwa ike batrị (BESS).
