Problems solved by technology
[0002] In the process of electric energy output by the power battery, energy loss inevitably occurs according to the function of the load. The usual power loss is divided into internal resistance loss and external resistance loss. These power losses are usually in the overall power consumption. Between 10% and 50% of the total, not only greatly reduces the economic benefits, but also is difficult to meet the strategy of sustainable development. Therefore, in order to minimize the loss of power battery power, it can be reduced from the power consumption of electrical equipment and power recovery. Starting from two aspects, however, after more than 50 years of development, especially in the field of microelectronics, low-power devices have reached a relative limit. Therefore, it is an effective means to solve the dilemma faced by the former by using the method of electric energy recovery to reduce electric energy loss.

Embodiment Construction
[0015] The present invention will be further described below in conjunction with embodiment.
[0016] Such as figure 1 As shown, the power battery electric energy recovery device proposed in this application includes an energy recovery module, a central amplification module and a terminal drive module.
[0017] The energy recovery module mainly uses the power loss between the solenoid and the power device circuit of the power battery to work. As shown in the figure, the induced electromotive force generated by the solenoid flows into the base of the transistor Q11 from the port IN, and the transistor Q11, transistor Q7, transistor Q20, transistor Q8, transistor Q21, and transistor Q12 form two completely symmetrical branches, which function as two current mirrors with synchronized current values, so that the current at the collector of transistor Q21 is the same as that at the collector of transistor Q7 The magnitude of the current is the same, and the induced electromotive f...

The invention relates to a power battery electric energy recovery device, and the device comprises an energy recovery module, a central amplification module and a terminal driving module. The electric energy recovery device can recover the electric energy loss of the power module of the power battery; recycling of electric energy is completed through electromagnetic induction between the solenoid and fluctuating current around the power module of the power battery. The energy recovery module completes electric energy preliminary recovery through electromagnetic induction between a solenoid and a power device circuit of the power battery, and electric energy loss generates variable magnetic flux so that induced electromotive force can be generated in the solenoid. The central amplification module further improves the energy level of the induced electromotive force at the energy recovery module, and completes core energy amplification. The terminal driving module further improves the energy supply capacity of the whole recovery device, and the working efficiency of the energy recovery device is improved.
