The invention discloses a dynamic current doubling circuit and a linear voltage regulator integrated with the circuit. The dynamic current doubling circuit can dynamically regulate the magnitude of the output bias voltage according to the condition of an external output load. The low dropout linear voltage regulator integrated with the dynamic current doubling circuit can couple a leaping voltage to the dynamic current doubling circuit by a capacitor within a very short time when the output voltage leaps, a tail current source current of the differential pairs of a transconductance operational amplifier is increased instantaneously by controlling the magnitude of the bias voltage, the gate voltage of a regulating tube can be regulated rapidly, the problem of low slew rate caused by the slow change of the gate voltage of the regulating tube is solved, and the transconductance of the differential pair tube is increased by the increase of the tail current source current of the differential pairs, thereby increasing bandwidth of LDO (low dropout regulator), and the tail current source current only increases instantaneously without excessive power consumption.

The invention aims to provide a heating system of a power battery of a pure electric automobile and a control method thereof, which are used for eliminating the influence of low temperature on the performance of the power battery of the pure electric automobile to ensure that the pure electric automobile can be used in severe cold areas in winter. The heating system comprises a battery heating device which is arranged in a battery pack, wherein the battery heating device is provided with a hollow radiating fin; and the radiating fin is provided with a water inlet and a water outlet. The heating system is characterized by also comprising an auxiliary heater, wherein the auxiliary heater is connected with a fuel supply device; a heat exchanger is arranged in the auxiliary heater; the water inlet of the heat exchanger is communicated with the water outlet of an expansion water tank by a water pump and a water pipe; the water outlet of the heat exchanger is communicated with the water inlet of the radiating fin by an electric control valve; the water outlet of the radiating fine is communicated with the water inlet of the expansion water tank; the electric control valve, the auxiliaryheater and the water pump are connected with a vehicle controller and are controlled by the vehicle controller; and the vehicle controller is also connected with a battery management system.

An assembly comprising a base fixed to the bowl, provided with a toilet rim and an air aspiration device from the toilet bowl. The base (1) contains an extension (12) provided with presence detection window (13) oriented on top of the rim (2) and forming an aspiration channel (14) opening in the bowl. An aspiration device control circuit has an infra-red detector in the window (13) to detect a presence on the rim (2) and a power source (10) for the circuit and the aspiration device (6).
