Embodiment
Below in conjunction with embodiment surplus lithium battery batteries is gushed in the present invention and do detailed explanation.
Fig. 1 is the inside connection diagram that surplus lithium battery batteries is gushed in the present invention.
Surplus lithium battery batteries is gushed in the present invention, using the battery cell string for N that comprises series connection, the E point is a cathode output end, the B point is a cathode output end, be connected in series at least 1 battery cell (N+1) as the reserve battery monomer at battery anode end B point, normal operating condition, the output of battery pack is individual in positive terminal B point and the output of negative pole end E point with the battery cell string by the N of series connection, the reserve battery monomer is a series connection, A, A1, A2 are arranged respectively ... several tie points of Ax, the positive terminal Ax of last reserve battery monomer is in open-circuit condition.
The model with battery cell in reserve battery monomer and the battery pack is identical, voltage is identical, the charging electrical characteristics are identical.
The reserve battery monomer is parallel with battery cell protector (see figure 3); battery cell protector quantity is identical with the reserve battery monomer; the input of battery cell protector connects the positive terminal A point and the negative pole end E point of battery pack; output and each battery cell parallel connection are exactly and B, A, A1, A2 ... the Ax point connects.
The battery cell protector is a small-sized charger, adopts the Switching Power Supply principle, is furnished with equalizing control circuit; The battery cell protector is used to safeguard the reserve battery monomer, is provided with manual connection switch, 3 synchronous on/off patterns, access when enabling, time spent disconnection; The static power consumption stream of battery cell protector is not more than 1mA.Charging current is set at 1A; The start and stop condition of battery cell protector is to start when the SOC of protected battery cell drops to 30%, gives when protected battery cell charging with the electric current of 1A; When the SOC of protected battery cell rises to 90%, stop to protected battery cell charging.The SOC of reserve battery monomer is remained between the 30%-90%.
Gush in the surplus lithium battery batteries and be provided with battery manager, battery manager comprises system control module, display and cell voltage and temperature detecting module (see figure 4), and the quantity summation with battery cell and reserve battery monomer in the quantity of cell voltage and temperature detecting module and the battery pack adapts.Battery manager is used to detect functions such as the voltage status, state of temperature, SOC, limiting alarm of each battery cell.Wherein cell voltage, temperature detecting module are used for the unit for electrical property parameters measurement to single pond monomer of battery pack; The system control module of battery management is used for the unit for electrical property parameters statistics of battery cell that cell voltage, temperature detecting module are measured, and carries out system's control by the program of setting, and shows the relevant parameter of all cells through display.
At the casing that all is assemblied in battery pack with battery cell, backup cell, battery cell protector and battery manager, identical with the fixed form of reserce cell monomer with battery cell.Because the maximum of lithium battery battery core output ampere-hour number is limited, battery cell wherein is being formed in parallel of several battery of the same race, and back in parallel output voltage is constant, and the ampere-hour number is the sum total of several battery.
Gush surplus lithium battery batteries when being absorbed in disabled state when described, replace with the reserve battery monomer and impaired using the battery cell individuality, the following (see figure 2) of its concrete grammar:
1) utilize described battery manager to determine defective cell monomer individuality, such as using battery cell between D point among the figure and the C point;
2) the defective cell monomer individuality between disconnection D point and the C point is carried out the electric screen protection, uses special-purpose radome insulation blocking usually, and directly connects cut-off point D point and C point with lead;
3) utilize hand switch in the battery protector to disconnect battery protector on the individuality (N+1) that the connection battery anode end B in the reserve battery monomer order;
4) the positive terminal line with battery pack disconnects from former tie point B point, the anodal A point of described reserve battery individuality of 3 step of reconfiguration to the (N+1 only).New connected mode is a cathode output end with the A point, still keeps N battery cell from the A point to the E point, guarantees the normal operation of this battery pack.
Illustrate, when the state-of-charge of all batteries is identical (when the quiescent voltage of each battery cell is identical), just can seal in reserve battery monomer (N+1 only).
The reserce cell monomer is at least one in this programme, when being two when above, obviously, can use the same method and make secondary, replace for three times ..., guarantee electric motor car continue travel and return factory.
In order to guarantee the normal use of electric motor car, after returning factory, should in time maintain usually this battery pack, impaired battery cell is changed, recover original connection status (see figure 1), still be in the surplus state of gushing of N+1 with the battery pack that guarantees electric motor car.
