Embodiment
With reference to Fig. 1, a kind of battery formation energy recovery device based on the local DC suppling network, comprise power supply 1, CAN communication network 2 and centralized computer control system 3, described power supply 1 forms DC suppling network by least two group rectification filtering module parallel connections, described power supply 1 is connected with charging by DC bus 7 and electric weight detection module 4, low pressure promote circuit module 5, and the control end that described charging and electric weight detection module 4 and low pressure promote circuit module 5 is connected with centralized computer control system 3 by CAN communication network 2 respectively.
Be further used as preferred embodiment, low pressure promotes circuit module 5 and also is connected with E-load machine module 6, and the control end of described E-load machine module 6 is connected with centralized computer control system 3 by CAN communication network 2.
Be further used as preferred embodiment, be connected on charging on DC bus 7 and electric weight detection module 4, low pressure promotes circuit module 5 can be for a plurality of.
Be further used as preferred embodiment, communication power supply is three-phase.
Be further used as preferred embodiment, the voltage of described power supply 1 is 590VDC.
With reference to Fig. 2, three-phase alternating-current supply is through diode D1-D6 three phase rectifier, then forms a powerful 590V DC power supply through capacitor C 1, C2, inductance L 1 filtering.Determine N(N >=2 according to the battery production amount) parallel running of platform 590V DC power supply.
With reference to Fig. 3, charging and electric weight detection module 4 adopt the half bridge circuit topological structure, and by CPU, according to predefined program control charging voltage, charging current and charging interval, the electric weight detection module records the various parameters of battery charging in detail simultaneously.
With reference to Fig. 4, low pressure promotes circuit module 5 and adopts push-pull type topological structure DC/DC converter, battery discharging energy rises to the fluctuation ratio depending on electrical network than the high 5-8V(of the network voltage of rectifier power supply through the DC/DC converter by voltage), when flowing on DC network, the electric energy that makes recovery preferentially taken.
In the forming and capacity dividing process of battery production, some batteries need charging, and some batteries need electric discharge, and at this moment centralized computer control system 3 control chargings and electric weight detection module 4, low pressure promote circuit module 5 and carries out corresponding program.During charging, charging and electric weight detection module 4 absorb energy as the battery charging from DC bus; The energy back that during electric discharge, low pressure lifting circuit module 5 is put battery is to DC bus.CAN communication network 2 is passed information back centralized computer control system 3 simultaneously, computer is according to the energy balance control strategy, control the priority of the start-up time of different rechargeable batteries and discharge battery, make as far as possible rechargeable energy equal discharge energy, accomplish that the rate of recovery is the highest.Power supply of the present invention is because be a DC suppling network, and a plurality of workshops of general factory share an electrical network, almost has the charging and discharging currents of up to ten thousand batteries pass in and out on DC network and flows, and basically can keep electric current to pass in and out balance.When period, discharge energy was greater than rechargeable energy extremely individually, computer acquisition can start immediately E-load machine module 6 after information, and superfluous energy is discharged, and guarantees that battery changes into the work follow procedure and carries out.The energy feedback of one Battery pack electric discharge is given second group and the charging of N Battery pack to DC bus, when the second Battery pack and the electric discharge of N Battery pack, again energy feedback is arrived to DC bus.Energy recycling use like this, saved the energy greatly, reduced the cost of battery forming and capacity dividing.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement all are included in the application's claim limited range.
