Charging cost for battery pack

[z_TKS]

Hi,



I have a 60V 100Ah Li-ion Battery pack

Electrical tariff is $0.15/kWh



How much will it cost me to charge the battery pack? ( assume it is totally flat).



60V 100Ah = 60V x 100Ah = 6kW



1C charge at 60V 100A = 6kW



Cost per charge = $0.15 x 6kW = $0.9/charge.



Could someone varify if my calculations are correct?



Thanks,

TK
