Turning on the switch Ku 10022219#Single number A0101 Page 11/Total 21 page 1013181011-0 M436952 :1〇1年_ 14 ά费正轻页 and turn-off control can be found in Figure 2, Figure 4 and Figure 6. The grid section shown in the figure performs the 'switching control module 1', and the first switch can be controlled when the current flowing through the first switching device 1 or the second switching device 20 crosses zero or the current crosses zero. The device 1G and the second switching device 2Q perform switching state switching. The heating circuit provided by the present invention has the following advantages: (1) Since the charge and discharge direction of the second charge and discharge circuit is opposite to the charge and discharge direction of the first charge and discharge circuit in terms of the charge storage element, the electric energy can be An alternating reciprocating flow between the battery E1, the charge storage element, and the second battery £2, whereby the generated current can cause the first damper element R1 and the second damper element R2 to heat up, thereby making the first battery £1 and The second battery E2 is heated, and the first battery E1 and the second battery E2 are alternately heated, and the heating efficiency is high. (2) Due to the current limiting action of the current memory element and only a single charge and discharge circuit is formed every time period, so that the first battery E1 and the second battery E2 and the first switching device ι and the second switching device 2 are passed. The current is small, and the configuration of the charge and discharge circuit and the presence of the first current memory element L1 and the second current memory element L2 can further restrict the flow through the first battery E1 and the second battery E2 and the first switching device 1 And the current of the second switching device 20 thus avoids large currents damaging the battery and the switching device. (3) When the unidirectional current limit is used, 'the discharge efficiency of the first battery E1 and the second battery E2 can be increased' while the reverse charging current is limited to avoid damage to the first battery E1 and the second battery E2, thereby ensuring The heat efficiency is further increased while not damaging the first battery Ei and the second battery E2 and the switching device. (4) In the heating circuit provided by this creation, the charge memory element is connected in series with the battery. When the battery is heated, due to the storage of the series of charge memory elements 1013181011-0 10022219# single number A0101 page 12 / 21 pages M436952 On the 14th and the 14th of May, the nuclear power is replaced by the ^ page, which can avoid the safety problem caused by the failure of the switching device and the short circuit, thereby effectively protecting the battery.
