May 10th The same page is modified or changed by the same page. In order to achieve the effect of energy storage, these should be included in the protection of this creation. According to the technical solution of the present creation, when the heating condition is ok, the switch control module 100 controls the switching device! Turning on, the battery E and the energy storage circuit are connected in series to form a loop, and the battery E can be discharged through the loop, that is, the first charge storage element C1 is charged. 'When the current in the loop passes through the current peak, the forward charge is zero, the first charge memory The component C1 starts to discharge through the loop, that is, the battery E is charged; and during the charging and discharging process of the battery e, the current in the loop can flow through the first damping element in the forward and reverse directions, and the first damping element passes through the first damping element.

The switch control module 1〇〇 controls the turn-on and turn-off of the first bidirectional switch K3. When the battery E needs to be heated, the first bidirectional switch pin can be turned on, such as stopping the heating or turning off the first bidirectional switch without heating. Κ3 can be. The switching device 1 is realized by using a first bidirectional switch Κ3 alone. The circuit is simple, occupies a small system area, and is easy to implement. However, in order to achieve the shutdown of the reverse current, the present invention also provides a preferred embodiment of the following device. Preferably, the opening and closing device 1 comprises a first one-way branch for realizing energy flow from the electric ship to the energy storage circuit and a second one-way branch for the energy realization circuit flowing to the battery port, and the switch control module 1〇 〇 is respectively connected with the first one-way branch and the second one-way branch, and is used for controlling the connected branch 10022162# single number Α〇101 page 9/total 45 pages 1〇131?6587, 〇ivhj〇 948 On May 10, 101, the turn-on and turn-off of the switch 丨 was controlled according to the turn-on and turn-off of the positive ridge few. When the battery needs to be heated, turning on both the first one-way branch and the second one-way branch, such as suspending heating, may choose to turn off one or both of the first one-way branch and the second one-way branch When the heating is not required, both the first one-way branch and the second one-way branch can be turned off. Preferably, both the first one-way branch and the second one-way branch are capable of being controlled by the switch control module 100 such that energy forward flow and reverse flow can be flexibly achieved. As another embodiment of the switching device 1, as shown in FIG. 3, the switching device 1 may include a f bidirectional switch K4 and a third bidirectional switch K5, and the second bidirectional switch Κ4 and the third bidirectional switch Κ5 are opposite to each other. Connecting in series to form the first one-way branch and the second one-way branch, the switch control module 1 is connected to the second bidirectional switch 4 and the third bidirectional switch 5, respectively, for controlling the second bidirectional switch Κ4 And turning on and off of the third bidirectional switch Κ5 to control the turning on and off of the first unidirectional branch and the second unidirectional branch. When the battery pack needs to be heated, the second bidirectional switches Κ4 and Κ5 may be turned on, and if the heating is suspended, one or both of the second bidirectional switch Κ4 and the third bidirectional switch Κ5 may be turned off, when heating is not required. The second bidirectional switch Κ4 and the third bidirectional switch Κ5 can be turned off. The switching device 1 is implemented to control the conduction and deactivation of the first one-way branch and the second one-way branch, respectively, to flexibly realize the forward and reverse energy flow of the circuit. As another embodiment of the switching device 1, as shown in FIG. 4, the switching device 1 includes a second switch Κ6, a second unidirectional semiconductor component dii, 1013176587-0, a third switch Κ7, and a third unidirectional semiconductor component. Di2, the second switch Κ6 and the second unidirectional semiconductor element D11 are connected in series to each other to constitute the first unidirectional branch, and the third switch Κ7 and the third unidirectional semiconductor element D12 are connected in series to each other to constitute the second one-way branch The switch control module 100 and the second switch 10〇22162 are numbered Α0101, page 10/total 45 pages, M436948, 101. May 10, the revised replacement page, the third open connection, respectively, for passing The turning on and off of the second opening 6 and the second switch K7 are controlled to control the turning on and off of the first one-way branch and the first one-way branch. In the switching device shown in Fig. 4, since the switches (i.e., the second switch K6 and the third switch Κ7) are present on both of the one-way branches, the shut-off function is performed at the same time as the energy flows in the forward and reverse directions. Preferably, the switching device 1 may further comprise a resistor in series with the first one-way branch and/or the second one-way branch for reducing the current of the battery heating circuit to avoid excessive current in the circuit. The battery is causing damage. For example, a resistor R6 connected in series with the second bidirectional switch K4 and the second bidirectional switch K5 may be added to the switching device 第 shown in Fig. 3 to obtain another implementation of the switching device 1, as shown in Fig. 5. Also shown in Fig. 6 is an embodiment of the switching device 1, which is obtained by series-connecting resistors R2 and resistance ribs on two one-way branches of the switching device 丨 shown in Fig. 4. As is known to those skilled in the art, circuit devices each have a nominal voltage that is a standard value of the operating voltage that the circuit device can withstand. When the voltage value on the circuit device exceeds its rated voltage, it will cause damage to the circuit device and affect the safe operation of the entire circuit. Preferably, the switch control module 1 〇〇 is further configured to control the switch device 丨 to be turned off after the first positive half cycle of the current flowing through the switch device i after the switch device 丨 is turned on, and the switch device 1 is applied when the switch device 1 is turned off. The voltage to the switching device i is less than the rated voltage of the switching device 1. Thereby, the freewheeling action of the freewheeling circuit 20 and the selection of the turn-off timing of the switching device 1 can further prevent the switching device 1 from being damaged due to excessive induced voltage generated by the first current memory element L1 in the circuit, so that heating The circuit is more secure and has less impact on the entire circuit. In addition, by selecting the turn-off timing of the switching device ,, the induced voltage generated by the first current memory element L1 can be reduced to some extent, 1013176587-0 10022162#单号A〇101 Page 11 of 45 M436948 [l〇l年05;|i〇g corrects the gfe page so that the requirement for the freewheeling capability of the freewheeling circuit 20 can be reduced, so that the element having a smaller characteristic parameter such as power or capacity is used in the "IL circuit 20. The device is fine. Wherein, the turn-off timing may be, for example, a time interval from 30 degrees before the zero-crossing of the current flowing through the switching device 到 to 30 degrees before the zero-crossing of the peak of the next positive half-cycle, and the switching device 1 is turned off. The break time can be any time within the time interval. Of course, the creation is not limited to this. The specific turn-off timing should be determined according to the rated voltage of the switching device 1. For example, for different rated voltages, it may be the negative half-cycle peak of the current flowing through the switching device 1. The time interval from 60 degrees before the zero crossing to 6 degrees after the zero crossing of the peak of the next positive half cycle" Because during the charging and discharging of the battery E, when the battery 5 is reversely charged, the energy will not be fully charged. Returning to the battery E' thus causes a decrease in energy in the next forward discharge of the battery e, reducing the heating efficiency of the heating circuit. Therefore, preferably, the switch control module 1 is used to control the switching device 1 to turn off when the current flowing through the switching device 1 after the switching device 1 is turned on is zero after the peak of the negative half cycle is zero to improve the heating efficiency of the heating circuit. And at this time, controlling the switching device 1 to turn off 'can minimize the voltage induced by the first current memory element Li' to minimize the voltage applied to the switching device 1, thereby avoiding high voltage damage to the switching device 1 ^ according to the present In an embodiment of the creation, the switch control module 1 is configured to control the switch device 1 to turn off before the zero-crossing of the current flowing through the switch device 1 after the switch device 1 is turned on, as shown in FIG. As shown, the freewheeling circuit 20 can include a fourth switch K20 and a fifth unidirectional semiconductor component D20 that are connected to each other. The switch control module 100 is connected to the fourth switch K20 for after the switching device 1 is turned on and off. Controlling the fourth switch K20 to be turned on, and 10022162#single number A0101 page 12/total 45 pages 1013176587-0 M436948 101. The current of the current flow to the battery E is a predetermined value (for example, zero) ) , K20 controls the fourth switch is turned off. The freewheeling circuit 20 may be connected in parallel across the battery e, or may be connected at one end to the third switch K7 and the third unidirectional semiconductor component 2 of the second unidirectional branch of the switching device 1 as shown in FIG. The current value connected to the battery at the other end is a current value that does not cause the voltage applied to the switching device 1 when the switching device 1 is turned off to be greater than or equal to the rated voltage of the switching device 1, and the current value may be according to the switching device Set the rated voltage. According to another embodiment of the present invention, the switch control module 1 is configured to control the switch device 1 to turn off after the zero-crossing of the positive half-cycle of the current flowing through the switch device 1 after the switch device 1 is turned on, such as the eighth As shown, the freewheeling circuit 20 may include a fourth unidirectional semiconductor element D21, a second damper element R21, and a second charge MEM element C21 'fourth unidirectional semiconductor element]) 21 and a second damper element R21 in parallel and then The second charge memory element C2i is connected in series. After the switching device 1 is turned on and off again, the first current memory element Li can be freewheeled through the fourth unidirectional semiconductor element D21 and the second charge memory element C21, and the second damping element R21 is used for The energy stored on the second charge storage element C21 is released. The freewheeling circuit 20 may be connected in parallel across the battery e, or may be connected at one end to the second switch K6 and the second unidirectional semiconductor component D11 of the first unidirectional branch of the switching device 1 as shown in FIG. Between the other end and the battery Ε» 1013176587-0 The current in the circuit is small (ie, approximately zero) due to the control switch device 1 being turned off near the zero crossing after the negative half cycle of the current flowing through the switching device 1. When the switching device 1 is turned off, the voltage applied to the switching device 1 is lower than the rated voltage of the switching device 1, so that the requirement for the freewheeling capability of the freewheeling circuit 2〇 can be minimized, or even the above freewheeling is not required. Circuit 10022162^Single number A0101 Page 13 of 45 M436948 ιοί年ίο日修正§ § ^ Page 20. A person skilled in the art can obtain, by a limited number of tests, a range of the off time interval of the switching device 1 which causes the voltage applied to the switching device 1 when the switching device 1 is turned off to be smaller than the rated voltage of the switching device 1. The energy superimposing unit is connected to the energy storage circuit for superimposing the energy in the energy storage circuit and the energy in the battery E after the switching device 1 is turned on and off again, so that when the switching device 1 is turned on again , improve the discharge current in the heating circuit, thereby improving the working efficiency of the heating circuit.
