The required power (step 402); the second discharge is during the discharge, the secondary battery U receives the power from the discharge circuit 22 and stores it (step 4〇3), and then the second charge is the charger 13 The stored electric energy of the secondary battery 12 is converted into the charging power to the main battery 11 (step 4 haiku, in order to avoid the battery being insufficient to charge, it is determined that the main battery U power is sufficient (step 4〇5) 201010241? If sufficient, repeat Steps 402 to 404; if not, proceed to step 401 to repeat the foregoing process. As shown in Table 3, a main battery u having a capacity of 34,56 watts is taken as an example, and the primary electric energy can be supplied to charge and discharge control. system 2 multiple cycles; as shown in Table 4, for the charge and discharge calculation of the first cycle (four steps), if the main battery u is charged by the ionization peak time at night, the power saving effect will be better. Whether the main battery 充电 charges the battery 3 through the charging circuit 21, the battery 3 discharges the discharge circuit 22, the discharge circuit 22 charges the secondary battery 12, or the secondary battery 12 passes the charger 13 θ to the main battery 11 Charging is a conversion from DC to DC.

The module 1 and the control method have the following advantages: 1. Power conversion efficiency is good: no matter the main battery u charges the livestock battery 3 through the charging circuit 21, the battery 3 discharges the discharge circuit 22, and the discharge circuit 22 pairs the secondary battery 12 The charging, or the secondary battery 12 charges the main battery 11 through the charger 13, which is a DC-to-DC conversion and thus has good power conversion efficiency and does not waste power. 2_Discharged electricity can be recycled: using the secondary battery 12 to consume the power that the battery 3 is discharged, it will not cause waste, and it will not generate heat due to power consumption © to increase the indoor temperature, so there is no need to install a fan to dissipate heat. . 3. Saving electricity costs: The main battery U can be fully charged and the electric energy can be supplied to the charging and discharging. The control system 2 is cycled several times. If the main battery 11 is charged by the ionization peak time at night, the power saving effect will be better. 4. The factory design is simplistic and can effectively use the space: no need to modify the transformer box and configure multiple distribution lines, which can reduce the design cost of the factory, plus the equipment that does not have to buy Amber and occupy the volume, so the utility space can be effectively utilized. .
