In the present embodiment, the MCGS includes display screen or touch screen;Each battery pack 60 include multiple series connection and/ Or battery cell in parallel;The normal electric power supply 30 includes battery.
The operation principle of energy-accumulating power station 100 of the present invention will be illustrated below.
When work, the normal electric power supply 30 is powered to the MCGS and each BMS, and the MCGS tranmitting data registers signal is to every A BMS, the circuit breaker Q F are closed.Be provided with preset program in each BMS, the preset program according to receive when Clock signal controls closure or the disconnection of corresponding first switch K1.
In the present embodiment, 8 points of morning is typically peak times of power consumption, and the energy-accumulating power station 100 needs to discharge, therefore, The preset program can control the closure of corresponding first switch K1 when receiving 8 points of clock signal in morning;The morning 12 The energy-accumulating power station 100 does not work usually after point, and therefore, the preset program is receiving 12 points of clock signal of the morning When can control the disconnection of corresponding first switch K1;It is usually the electricity of the low peak period of electricity consumption and the electricity charge than daytime after 1:00 AM To take cheaply, this period can save the electricity charge to the charging of the energy-accumulating power station 100, therefore, the energy-accumulating power station after 1:00 AM 100 can charge, and the preset program can control corresponding first switch in the clock signal for receiving 1:00 AM The closure of K1;When reaching 5:00 AM, the energy-accumulating power station 100 fills with electricity, and the energy-accumulating power station 100 can stop at this time It only works, therefore, the preset program can control corresponding first switch K1 when receiving the clock signal of 5:00 AM point Disconnection.It follows that the energy-accumulating power station only needs 8 hours of work for 100 1 days, other time can not work, when described When energy-accumulating power station 100 works, each first switch K1 is closed;When the energy-accumulating power station 100 does not work, each first switch K1 It disconnects.In other embodiments, the working hour number of the energy-accumulating power station 100 and the time span of each working hour are equal It can be adjusted correspondingly according to actual conditions, the preset program can also be adjusted accordingly according to actual conditions.
When each first switch K1 is closed, normal 30 anode of electric power supply passes through each first switch K1 and the coil L1 is connected with the cathode of the normal electric power supply 30, has electric current to flow through in the coil L1, the second switch K2 is closed.It is described to fill Discharge module 80 carries out corresponding battery pack 60 by the circuit breaker Q F, the relay J1 and corresponding acquisition module 50 Charge or discharge.Each battery pack 60 is by corresponding acquisition module 50, the relay J1 and the circuit breaker Q F to described Voltage transformation module 90 is powered.The voltage that each battery pack 60 exports is converted into the normal electricity electricity by the voltage transformation module 90 The charging voltage in source 30, and charge for the normal electric power supply 30, and power for the MCGS 10 and each BMS 20.
When each first switch K1 is disconnected, there is no electric current to flow through in the coil L1, the second switch K2 is disconnected.Often A acquisition module 50 and other electron component do not work, and the charge-discharge modules 80 do not give 60 charge or discharge of each battery pack, Each battery pack 60 does not give the voltage transformation module 90 to power, and the MCGS and each BMS enter dormant state.
In the present embodiment, the circuit breaker Q F is generally in closed state, only in certain special circumstances (as promptly Repair) when be just off.When the circuit breaker Q F is disconnected, the third switch K3 and the 4th switch K4 are disconnected Open, each acquisition module 50 and other electron component do not work, the charge-discharge modules 80 give each battery pack 60 charging or Electric discharge, each battery pack 60 do not give the voltage transformation module 90 to power.
The present invention is by being arranged the first switch K1 that is connected with each BMS 20 and being connected with each first switch K1 Relay J1, and the closure of corresponding first switch K1 is controlled according to the clock signal received by each BMS 20 or is broken It opens, to control closure or the disconnection of the relay J1, and then controls whether each acquisition module 50 works and described fill Whether discharge module 80 gives the progress charge or discharge of each battery pack 60, therefore, the acquisition module 50 in the energy-accumulating power station 100 And other electron component can be stopped in certain periods, without daily 24 hours continue workings, to extend State the service life of energy-accumulating power station 100.
The present invention is not only in the description and the implementation described, therefore for the personage of familiar field Other advantage and modification is easily implemented, therefore in the essence without departing substantially from universal defined by claim and equivalency range In the case of refreshing and range, the present invention is not limited to specific details, representative equipment and diagrams shown and described herein Example.
