Abstract: A battery-protecting apparatus is electrically connected to a secondary battery, a generator and a load unit of a vehicle. The generator provides electricity to the battery via the battery-protecting apparatus. The battery provides electricity to the load unit via the battery-protecting apparatus. The battery-protecting apparatus includes a detection unit, a switch, a processor, a controlling unit, a discharging loop, a wireless communication unit and a security loop.

Abstract: A vehicle anti-theft device, including a processor, a current control unit, a first bluetooth transmitter, and an operator, wherein the processor, the current control unit and a signal transmitter are linked to a vehicle starter battery. The processor is electrically connected to the current control unit, the first bluetooth transmitter, a vehicle electric generator, and battery cells of the starter battery. The processor is used to control operation of the current control unit, and the current control unit is used to control the starter battery to output current to the vehicle circuitry system. The current control unit includes a large current circuit and a small current circuit. The large current circuit is provided with a single-pole relay. The small current circuit comprises a self-resetting fuse.

Abstract: active vehicle recharge protection device includes a detection unit, a control unit and an annunciator. The detection unit is connected electrically with a recharge power source and is a voltage detection circuit used to detect the output voltage of the recharge power source. The control unit is connected electrically with the detection unit and a battery. In addition, the control unit is a microcontroller used to control the supply of electric energy to the battery based upon the voltage detected by the detection unit. The annunciator is connected electrically with the control unit. Overvoltage protection and undervoltage protection are executed to the battery by the detection unit and the control unit, preventing the battery from being charged at an abnormal voltage to affect the accumulation capacity and the lifetime of use of the battery.

Abstract: A protection device for battery assembly includes a battery unit having multiple secondary Lithium batteries and the battery unit is electrically connected with a detection-control unit which is electrically connected to a by-pass which is a charge/discharge circuit. The detection-control unit has a voltage detection circuit and a micro controller unit to detect output voltage of the battery unit. A receiving device is electrically connected to the detection-control unit to receive wireless signals from a remote controller. The receiving device transmits signals to the detection-control unit. An emitting device is electrically connected to the detection-control unit to send signals to the remote controller when the battery unit has abnormal voltages. The battery unit is monitored and controlled by the detection-control device.

Abstract: The present invention discloses an active cloud power management system for a secondary battery. This power management system is able to actively handle electrical properties of the secondary battery and provide a user with a general status message or a real time early warning message about the secondary battery, so that an efficiency of use and safety of the secondary battery can be maintained by active monitoring and reminding services.
