Disclosed are a carrier communication method based on electric automobile charging/discharging, comprising the following steps: S1: after being powered up and started, an electric automobile detecting whether a carrier signal from a peripheral device is received through an interface wire harness and whether the carrier signal is correct; S2: when detecting the carrier signal and detecting that the carrier signal is correct, the electric automobile receiving the carrier signal through the interface wire harness; and S3: the electric automobile performing coupling and filtering on the received carrier signal to convert the carrier signal into a standard carrier signal, and demodulating the standard carrier signal into a digital signal to obtain information of the peripheral device. The method, on the basis of not increasing the number of wire harness, may implement data transmission and sharing between an automobile and ECU modules of a peripheral device, and carrier communication with other signal lines as communication media at the same time, so as to avoid construction and investment of a new communication network, and reduce manufacturing cost and maintenance difficulty. Further disclosed are a carrier communication system and a carrier apparatus based on electric automobile charging/discharging.

Le dispositif de surveillance d'une alimentation électrique (2) est alimenté par cette alimentation électrique. Il comporte une batterie (3) formant alimentation secondaire et qui se déclenche en en cas de disparition de l'alimentation primaire (2). Un circuit de gestion (5) contrôle la tension (V batt ) aux bornes de la batterie (3). Un comparateur (7) compare la tension mesurée aux bornes de la batterie (3) avec des première et deuxième valeurs de seuil. Un circuit de gestion (5) commande le passage d'un courant de décharge (I d ) aux bornes de la batterie (3), au moyen d'un interrupteur (10) et d'un compteur configuré pour compter une grandeur représentative du courant de décharge (I d ). Le circuit de gestion (5) peut avertir l'utilisateur que la batterie est défaillante en fonction de la valeur du compteur.
摘要:
A drive control circuit (200) of a backlight (220) includes a drive circuit (240) that drives the backlight (220), a voltage detection unit (250) that detects whether or not a supply voltage Vp from a battery (210) is less than or equal to a threshold value, and a controller (260) that controls the operation of the drive circuit (240). When the supply voltage Vp from the battery (210) is less than or equal to the threshold value, the drive circuit (240) changes a drive current to be supplied to the backlight (220) to a low current value. Furthermore, in response to a change in the drive current, the controller (260) provides, to the drive circuit (240), a PWM signal to extend a time period for which the backlight (220) are on.

A battery warm up system according to the present disclosure includes an open signal receiving unit to receive a door open signal for opening a door of a vehicle, a temperature measuring unit to measure a temperature of a battery pack connected to a starter of the vehicle, a control unit to output a forced discharging start signal by referring to information associated with the temperature measured by the temperature measuring unit when the door open signal is received by the open signal receiving unit, and a forced discharging circuit unit to force a plurality of battery modules constituting the battery pack to be discharged in response to the forced discharging start signal. According to the present disclosure, cold startability of a vehicle may be significantly improved using heat generation of a battery itself while not causing a great change to an existing power supply system for vehicles, and efficient warm up may be achieved without unnecessary consumption of the battery pack by allowing a vehicle user to select a time to start warming up.
摘要:
In a battery voltage monitoring device including a battery voltage monitoring IC coupled to a plurality of unit cell groups configuring an assembled battery by being serially coupled in multiple stages and measuring voltage of each of the unit cells and a system control unit controlling the whole, communication between the system control unit and the battery voltage monitoring ICs is realized in consideration of fail-safe. The system control unit and the plurality of battery voltage monitoring ICs are coupled to each other by a communication path using a daisy chain. The battery voltage monitoring IC has a placement setting pin designating, by a binary code, a unit cell group to which the IC is coupled, in the unit cell groups. When it is detected that the Hamming distance between the code indicative of coupling to a group of the highest potential or a group of the lowest potential and a state actually set in the placement setting pin is 1, occurrence of failure such as line disconnection, short-circuit, or the like in the placement setting pin is determined, and an output to a communication path is interrupted by being set to high impedance.
