OPERATION OF NICKEL-HYDROGEN STORAGE BATTERY (NHSB) Russian patent published in 2010 - IPC H01M10/44 

FIELD: power engineering.

SUBSTANCE: proposed method consists in staging charge-discharge cycles with control of control storage batteries (CB) and periodical storage in discharged state. Note here that discharged NHSB is periodically charged to compensate its self-discharge. Note also that storage is started after charging to (0.1-0.2)C_rat, where C_rat is rated capacity, while in storage it is charged to initial charge of CB. Besides duration of the first storage term between rechargers is set to make 30 days, while duration of subsequent terms is corrected in every next recharging proceeding from actual capacity of self-charge for preceding storage term defined by the following formula: T_i=T_pr·ΔC_rech/ΔC_st, where T_i is duration of the next storage term; T_pr is duration of previous storage term; ΔC_rech is capacity produced in recharging; ΔC_st is capacity during previous storage term defined by the formula: ΔC_st=ΔP_st·K_E, where ΔP_st is pressure reduction in CB during previous storage term; K_E factor to convert pressure in capacity.

EFFECT: higher efficiency and reliability of NHSB.
