摘要： A battery protection device (200) includes a first transistor (M1), a switch control circuit (210), a controller (240), and a photocoupler (230). The first transistor (M1) is connected between one of the pack terminals (P+, P-) of a battery pack (10a) and a battery module (100) and controls a current flow between the pack terminals (P+, P-) and the battery module (100). The switch control circuit (210) outputs a first control signal (S1) for turning on or turning off the first transistor (M1). The controller (240) outputs a second control signal (S2). The photocoupler (230) is connected to a control terminal of the first transistor (M1), is turned on or turned off according to the second control signal (S2), and turns off the first transistor (M1) if turned on.

摘要： Embodiments herein provide an electrical protection circuit (100) for connecting an Energy Storage Unit, ESU (10) to a main power line (80). The electrical protection circuit (100) comprises first and second main terminals configured to be connected to a main power line, first and second ESU terminals connected to the ESU (10). The first main terminal is connected to the first ESU terminal via a first normally closed, NC, switch (20). The first main terminal is connected to the second main terminal via a normally open, NO switch (40). The first NC switch (20) is configured to be opened thereby to disconnect the ESU (10) from the main power line (80), and the NO switch (40) is configured to be closed thereby to bypass the ESU (10) from the main power line (80) in order to achieve electrical protection for the ESU (10).

摘要： A vehicular power supply system (100) includes a sensor unit (20) that detects a battery state of a storage battery (11) and a control unit (30) that performs instruction to perform energization and interruption of the energization between the storage battery and the electrical load (13) based on the battery state. The sensor unit includes a detection unit (21) that detects the battery state of the storage battery, a switch drive unit (23) that performs drive control of a switch unit (23a) provided between the storage battery and the electrical load, and a control unit (24) that controls the switch drive unit. The control unit switches between the energization and interruption of the energization between the storage battery and the electrical load. If determining an abnormality, the control unit determines whether to maintain the energization between the storage battery and the electrical load based on the battery state and switches between the energization and interruption of the energization based on the determination.

The power supply end is electrically connected with the load end at least through the first protection module, to implement the power supply module supplying power to the external load device at least through the first protection module. The first protection module is configured to monitor a power supply state of the power supply module supplying power to the external load device, and disconnect a connection between the power supply end and the load end or limit a current based on the power supply state. The output control circuit has a simple structure and can effectively ensure safety of a circuit.

摘要： A first device includes an outrush circuit including a resistor electrically disposed in series with first and second terminals of the first device and a switch electrically disposed in parallel with the resistor. The switch is controlled by an external signal received by the first device from a second device when the first device is communicably connected to the second device and the second device is electrically connected to the first and second terminals. When the first device receives the external signal, the switch is switched on after a startup time from receiving the external signal, such that electric current from a power source substantially passes through the switch. When the first device does not receive the external signal, the switch is switched off, such that electric current from the power source substantially passes through the resistor. The resistor limits electric current to the second device.
