The specific implementation of this creation will be described in more detail below with reference to the schematic diagram. The advantages and features of this creation will be clearer based on the following description and patent application scope. It should be noted that the drawings are all in a very simplified form and all use inaccurate proportions, which are only used to conveniently and clearly assist in explaining the purpose of this creative embodiment.

Please refer to the second to fifth figures, where the second figure shows a block diagram of the intelligent power management device provided by the preferred embodiment of the author; the third figure shows the intelligence provided by the preferred embodiment of the author A block diagram of part of the power management device; the fourth figure shows the flow chart of the intelligent power management device in the emergency charging mode provided by the preferred embodiment of the author; and the fifth figure shows the preferred implementation of the author The flow chart of the intelligent power management device provided in the example in the ordinary charging mode. As shown in the figure, an intelligent power management device 1 is used for a power vehicle, and is electrically connected to a battery 3 of a power vehicle and a generator 4.

Power vehicles can be locomotives, cars, trucks, trucks, Vehicles with internal combustion engines such as diesel vehicles. When the power carrier is switched to a power-on state, a power-on signal is generated. In practice, the power-on state is the state when a driver inserts the key of the power vehicle into the keyhole and rotates it to "on". Internal combustion engines include gasoline engines, kerosene engines, diesel engines and gas engines.

The intelligent power management device 1 includes a control module 11, a battery detection module 12, a trigger element 13, a first boost circuit 14, a current limiting module 15, a double electric layer capacitor assembly 16, a The first relay 17, a second relay 18 and an engine detection module 19.

The control module 11 is used to generate a start signal after receiving the power-on signal, which is step S101. The battery detection module 12 is electrically connected to the control module 11, and upon receiving the start signal, detects a battery voltage of the battery 3 and obtains a battery voltage value of the battery voltage. When the battery detection module 12 determines that the battery voltage value is lower than a start threshold, it generates a battery warning message, which is step S102. Among them, the start threshold is related to whether the power vehicle can be ignited and started, and when the battery voltage value is lower than the start threshold, it means that the battery voltage is too low.

Taking a spark plug in a power vehicle as an example, the spark plug will have a required voltage of the spark plug. When the battery voltage exceeds the required voltage of the spark plug, the spark plug can ignite to start the power vehicle; when the battery voltage is lower than the spark plug When voltage is required, the spark plug will not ignite and the power vehicle will not be able to start. The spark plug required voltage can also be regarded as the ignition required voltage of the power vehicle, because in the diesel car, the spark plug is not provided, but the diesel car still needs to reach an ignition required voltage to complete the ignition and start.

The trigger element 13 is electrically connected to the control module 11 for triggering a user to learn a battery warning message to generate a boost start signal, which is step S103. At the same time, the intelligent power management device 1 enters an emergency charging mode. The trigger element 13 can be a button, a handle, a push rod, etc. that can be triggered by the user. The trigger element 13 can also be a touch screen on the mobile device for the user to trigger remotely.

The first boosting circuit 14 is electrically connected to the battery 3 to receive the battery voltage and boost the battery voltage in the emergency charging mode to generate a rated charging voltage, which is step S104. Because the battery voltage is too low, the power vehicle may not be able to start and the electric double layer capacitor assembly 16 may not be charged. Therefore, in the emergency charging mode, the battery voltage that is too low is boosted to the rated charging voltage. The first boosting circuit 14 may include coils with different turns, boosted by the turns ratio of the coil, or may be a boost converter including circuits such as semiconductor elements and energy storage elements.

The current limiting module 15 is electrically connected to the first boosting circuit 14 for generating a charging limiting current after receiving the rated charging voltage, which is step S105. The electric double layer capacitor assembly 16 is electrically connected to the current limiting module 15 to receive a charging current limit for charging, thereby raising a capacitor voltage of the electric double layer capacitor assembly 16, namely steps S106 and S205, and connecting the electric double layer capacitor assembly 16 The capacitor voltage rises to a starting voltage greater than or equal to the starting threshold.

In more detail, the function of the current limiting module 15 is to limit the current charging the electric double-layer capacitor assembly 16 to prevent the electric double-layer capacitor assembly 16 from being damaged due to the sudden increase and decrease of the current. Especially in the case where the initial voltage of the electric double layer capacitor component 16 is 0, the charging current value cannot be too high. because Therefore, regardless of the magnitude of the voltage received by the current limiting module 15, a fixed charging limit current will be generated to stably charge the electric double layer capacitor component 16, which can also avoid damage to the electric double layer capacitor component 16 and thus extend The lifetime of the electric double layer capacitor assembly 16.

The first relay 17 is electrically connected to the control module 11 and the electric double-layer capacitor assembly 16 for conducting in operation. In more detail, when the control module 11 detects that the power vehicle is activated, it will generate a vehicle activation signal. When the first relay 17 receives the vehicle activation signal, it will be turned on, so that the electric double layer capacitor assembly 16 can output the starting voltage. The starting voltage output by the electric double layer capacitor assembly 16 can assist the power vehicle, so that the power vehicle reaches the ignition demand voltage at the moment of starting, and then completes the ignition to start, that is, steps S107 and S206.

Therefore, the intelligent power management device 1 provided by this work can use the excessively low battery voltage to provide an additional starting voltage when the battery voltage is too low, so that the power vehicle can still be ignited when the battery voltage is too low .

When the battery voltage is higher than or equal to the start threshold and the trigger element 13 is not triggered, the intelligent power management device 1 is in a normal charging mode. In the normal charging mode, after receiving the battery voltage, the first boosting circuit 14 directly outputs the battery voltage without boosting the battery voltage. The current limiting module 15 directly receives the battery voltage and generates the above-mentioned charging limiting current, and then charges the electric double layer capacitor assembly 16, that is, step S204.

Preferably, the intelligent power management device 1 uses the second relay 18 to electrically connect the first boost circuit 14 and the current limiting module 15, and is In order to avoid the danger of sparks caused by circuit conduction when the battery 3 is electrically connected, the control module 11 further includes a timing unit 111 and a control unit 112.

The timing unit 111 calculates a delay time when the power-on signal is detected. The delay time may be 30 seconds, 40 seconds, or other time sufficient for the user to install the intelligent power management device 1 (step S201). The control unit 112 is electrically connected to the timing unit 111, and in the normal charging mode, and when the timing unit 111 finishes calculating the delay time, it generates a first turn-on signal, which is step S202.

The second relay 18 is turned on after receiving the first turn-on signal, that is, step S203, and the current limiting module 15 can receive the battery voltage output by the first booster circuit 14 through the second relay 18, which is step S204. However, before the second relay 18 receives the first conduction signal, the entire circuit is disconnected, and no current will pass, so no spark will be generated. Preferably, the intelligent power management device 1 further includes a solid-state switch 27. The solid-state switch 27 is electrically connected to the control module 11 and is connected to the first relay 17 to have a high isolation effect, so that no spark will be generated when the first relay 17 is turned on, so as to ensure the safety.

In addition, the intelligent power management device 1 provided by this creation uses wires to electrically connect the battery 3, so there is no need to modify the power vehicle or destroy the original circuit settings, and it can be installed on the power vehicle in a simple step.

The engine detection module 19 is electrically connected to the control module 11 for detecting an engine 5 electrically connected to the generator 4. When it is detected that the engine 5 is in a running state, the first relay 17 is controlled by the control module 11 The electric double layer capacitor assembly 16 is electrically connected to the battery 3 and the generator 4.

When the engine 5 is in the running state, it means that the power vehicle has finished launching, it may be moving, or it may be at idle idle. At this time, the generator 4 will charge the electric double-layer capacitor assembly 16 and the battery 3 at the same time, instead of charging the electric double-layer capacitor assembly 16 by the battery 3. The power on the power carrier is provided by the electric double layer capacitor assembly 16. The electric double layer capacitor assembly 16 will provide voltage together with the battery 3 at the moment when the power vehicle is started; after the power carrier is started, the electric double layer capacitor assembly 16 will provide voltage in parallel with the generator 4. Therefore, the intelligent power management device 1 provided by this creation can reduce the burden on the original battery 3 and further extend the life of the battery 3. In addition, the generator 4 does not need to provide the power of the entire power carrier, and only needs to provide the power to charge the electric double layer capacitor assembly 16, so the life of the generator 4 can also be extended.

When the engine 5 is in a stopped state, the control module 11 will not turn on the first relay 17, thereby avoiding the electric double layer capacitor assembly 16 to provide the capacitor voltage all the time in an insignificant condition, so as to keep the capacitor voltage in the required state It can be provided to power vehicles. Generally speaking, when the engine 5 is in the running state, the generator 4 will also run; when the engine 5 is in the stopped state, the generator 4 will also stop. However, at present, some power vehicles have been running in the engine 5 The generator 4 is turned off in the state, so the intelligent power management device 1 directly detects the state of the engine 5 to avoid the possibility of misjudgment.

Regardless of whether the intelligent power management device 1 is in the emergency charging mode or the normal charging mode, the first boosting circuit 14 will receive the battery voltage of the battery 3. Only in emergency charging mode, the first boost circuit 14 boosts the battery voltage to form a rated charging voltage; in the ordinary charging mode, the first boosting circuit 14 does not boost the battery voltage, but directly outputs the battery voltage. The current limiting module 15 will receive the rated charging voltage in the emergency charging mode and the battery voltage in the normal charging mode, but regardless of the mode, the current limiting module 15 will be based on the received rated charging voltage or battery voltage. Generate charging limit current.

In this embodiment, the intelligent power management device 1 further includes a capacitor voltage detection module 21, a capacitor voltage balance module 22, a capacitor temperature detection module 23, a display module 24, and an operation interface 25与一个Output面26。 With an output interface 26. The electric double layer capacitor component 16 includes a plurality of electric double layer capacitors 161, in this embodiment, six electric double layer capacitors 161, and the maximum value of the capacitance voltage of each electric double layer capacitor 161 is 2 volts.

The capacitor voltage detection module 21 is electrically connected to the electric double layer capacitor component 16 and the control module 11, and is used to detect the capacitor voltage of the electric double layer capacitor component 16. When the capacitor voltage detection module 21 detects that the capacitor voltage reaches the upper limit, that is, the electric double-layer capacitor assembly 16 has been charged, the control module 11 will disconnect the second relay 18, so that the battery 3 will no longer The electric double layer capacitor assembly 16 is charged. The capacitor voltage detection module 21 includes a plurality of voltage detection circuits 211 corresponding to the electric double layer capacitor 161. Each voltage detection circuit 211 detects the capacitance voltage of each electric double layer capacitor 161. The voltage detection circuit 211 may be a photoelectric coupling circuit, so as to separate the optical signal from the electrical signal.

The capacitor voltage balancing module 22 is electrically connected to the electric double layer capacitor assembly 16 and the control module 11, and includes a plurality of voltage balancing circuits 221 corresponding to the electric double layer capacitor 161. When the control module 11 determines the electric double layer When at least two of the capacitors in the capacitor 161 have different voltages, the voltage balance circuit 221 balances the capacitor voltage of each electric double layer capacitor 161. The voltage balancing circuit 221 may be a circuit including at least one transistor.

The capacitor temperature detection module 23 is electrically connected to the control module 11 for detecting the temperature of a capacitor of the electric double-layer capacitor assembly 16, and when the capacitor temperature is determined to be higher than a temperature upper limit, the control module 11 Turn off the second relay 18 and the first relay 17. At this time, it indicates that the temperature of the electric double layer capacitor assembly 16 is abnormal, and it may be risky to continue to operate. Therefore, the control module 11 will turn off the second relay 18 and the first relay 17, so that the electric double layer capacitor assembly 16 will not receive the charging limit current for charging, nor will it provide the starting voltage to discharge, thereby reducing Possibility of danger.

The display module 24, the operation interface 25 and the output interface 26 are all electrically connected to the control module 11. The display module 24 can be used to display battery warning information, and can also be used to display the above-mentioned voltage value, current value, emergency charging mode and ordinary charging mode. The operation interface 25 is used for the user to operate, and the trigger element 13 can be disposed on the operation interface 25. The output interface 26 is used to output a power source information, wherein the power source information includes at least a battery voltage value, a rated charging voltage, a capacitor voltage, a starting voltage, or the above-mentioned data data.
