Description

Modular electric vehicle charger {Modular electric vehicle charger}

The present invention relates to a mobile electric vehicle charger that is assembled by modularly stacking and combining, and more specifically, to a modular mobile electric vehicle charger that stacks and combines a lower module including a battery module equipped with a battery management unit, a power management unit, and an energy management unit, and assembles the stacked modules by stacking and combining the lower module equipped with a driving unit according to a request signal for a charging amount required for an electric vehicle or a charging amount suitable for a price, and stacks and combines at least one stacked module, and stacks and combines a control module equipped with a battery management unit, a power management unit, and an energy management unit so as to control the lower module and the at least one stacked module stacked on top of the stacked module, thereby assembling the charging module so as to move the charging module to an electric vehicle that needs to be charged and charge it slowly or rapidly.

Recently, the automobile industry has been showing increasing interest in electric vehicles (EVs) that use electricity instead of fossil fuels such as gasoline and diesel, and consumer sales are also increasing. Since EVs are powered by electric energy rather than fossil fuels such as gasoline and diesel, they are environmentally friendly as they do not produce exhaust fumes compared to conventional gasoline or diesel vehicles, and they also produce less noise.

Electric vehicles, which have become the trend of eco-friendly vehicles, have shown considerable growth in a short period of time, but despite the enthusiastic support and policies of governments around the world, the market response has fallen short of expectations. The biggest obstacle preventing electric vehicles from completely replacing conventional internal combustion vehicles is the lack of sufficient charging infrastructure and the time required for charging.

To charge these electric vehicles, charging stands at charging stations, such as gas pumps at gas stations, are generally used, and most electric vehicle charging facilities currently being built are designed to install fixed charging stands in a certain area of a parking space and designate the parking area as an electric vehicle zone.

However, the fixed charging stands that are currently the mainstream of electric vehicle charging infrastructure worldwide have the problem that they use a certain portion of parking spaces exclusively for electric vehicles, causing parking disputes due to the designation of electric vehicle-only parking areas, and also have a very low utilization rate compared to the investment, failing to satisfy profitability or economic feasibility.

Meanwhile, in the case of the first-generation electric vehicle I-MiEV around 2010, the battery capacity installed in the vehicle was only 16 [kWh], and the electric vehicle Leaf from around the same time had a battery with a capacity of 24 [kWh]. However, the capacity of the batteries installed in recent mainstream electric vehicles is increasing significantly to around 80 [kWh], which is 3-4 times higher than before, and as the capacity of the batteries installed in electric vehicles increases, the output of electric vehicle chargers for rapid charging is also required, and the output of recent rapid charging stands exceeding 50 [kW], 100 [kW], 350 [kW], and even ultra-fast chargers exceeding 400 [kW] are appearing.

If high-power charging facilities such as these rapid or ultra-rapid charging stations are installed in high density in urban areas, there will be technical limitations on the supply capacity of the power grid that must supply the electricity demand, which will become a serious problem that is difficult to overcome in reality.

In particular, in a society like ours with a small land area and dense urban areas, if the distribution and market share of electric vehicles exceed a certain level, there is a high possibility that the electric vehicle charging infrastructure of this type will reach a saturation point where it will no longer be able to build a sufficient electric vehicle charging environment.

To solve the problems inherent in conventional fixed charging stands, mobile charging systems are being studied, but there is a problem that it is difficult to reuse them within a short period of time because it is difficult to match the amount of charge required for other electric vehicles or the amount of charge that is suitable for the price when the remaining charge is low after use.

Republic of Korea Patent No. 10-2378188 (2022.03.21.)

In addition, the driving unit (112) may be configured to include a driving motor (not shown in the drawing) installed at the bottom to rotate the plurality of wheels. If an autonomous driving system is included in the control module (130) to be described in detail later, the driving motor may be driven by the autonomous driving system of the control module (130) so that the assembled charging module (100) can be automatically moved.

In addition, the lower module (110) of the present invention is configured to include a plurality of coupling grooves (114) formed on the upper surface to correspond to a plurality of coupling protrusions (121) formed protruding on the lower surface of the stacked module (120) to be described in detail later.

The above-mentioned joining groove (114) is formed to correspond to the joining projection (121) of the stacking module (120) which will be described in detail later, thereby enabling the stacking module (120) to be joined in a stacking manner.

At this time, it is preferable that the coupling groove (114) be formed in a structure in which the battery module (102) installed inside the lower module (110) and the battery module (102) of the stacked module (120), which will be described in detail later, can be electrically connected. Any structure used in the past may be used. For example, the coupling groove (123) can be configured to include a second connection terminal (not shown in the drawing) corresponding to the first connection terminal formed in the coupling protrusion (121) of the stacked module (120), which will be described in detail later, and be connected.

In addition, it is preferable that the depth of the above-mentioned joining groove (114) be formed smaller than the protruding length of the joining projection (121) of the stacking module (120) to be described in detail later. This is to enable the stacking module (120) to be moved upward by the moving part (320) to be described in detail later and to be smoothly stacked.

The main component of the present invention, the laminated module (120),

A battery module (102) is installed inside, and at least one is laminated and combined on the upper part of the lower module (110) so that the battery module (102) of the lower module (110) and the battery module (102) installed inside are connected. The battery module (102) is stored in a laminated portion (400) to be described in detail later and is normally charged, and when a request signal from a user's terminal, i.e. a request signal for a charging amount required for an electric vehicle or a charging amount appropriate for a price, is received by the control portion (600) to be described in detail later, at least one is moved from the laminated portion (400) to the assembly rail (200) to be described in detail later.

The laminated module (120) of the present invention is configured to include a plurality of coupling protrusions (121) formed protrudingly on the lower surface and at positions adjacent to corners, and a plurality of coupling grooves (123) formed on the upper surface and formed to correspond to the plurality of coupling protrusions (121).

The above-mentioned plurality of coupling protrusions (121) and coupling grooves (123) are formed to correspond to each other, thereby enabling one stacked module (120) to be laminated and coupled with another stacked module (120).

At this time, it is preferable that the plurality of coupling protrusions (121) and coupling grooves (123) are formed in a structure in which a battery module (102) of one stacked module (120) and a battery module (102) of another stacked module (120) can be electrically connected. Any structure used in the past may be used. For example, the coupling protrusion (121) may include a first connection terminal (not shown in the drawing) formed in the center, and the coupling groove (123) may include a second connection terminal (not shown in the drawing) corresponding to the first connection terminal, so that they can be connected.

In addition, it is preferable that the protrusion length of the above-mentioned coupling projection (121) be formed to be greater than the depth of the above-mentioned coupling groove (123). This is to enable the stacking module (120) to be moved upward and stacked by the moving part (320) to be described in detail later.

Meanwhile, the battery module (102) installed inside the lower module (110) and the stacked module (120) of the present invention is configured to include a plurality of battery cells.

The above battery module (102) can use a secondary battery, and among the types of secondary batteries, LiB (lithium ion battery) is receiving the most attention, and there are RFB (redox flow battery), NaS (sodium sulfur battery), and Super Capacitor.

The above battery module (102) may be composed of a cell, a module, and a pack. The cell must have a high capacity per unit volume to achieve maximum performance in a limited space, and must have a much longer lifespan than batteries for general mobile devices. In addition, it must have high reliability and stability at low/high temperatures.

Multiple cells are grouped together into a frame to provide additional protection from external shocks such as heat and vibration. This is called a module.

And by adding several of these modules, a battery management system (BMS) and a cooling device, etc., a battery pack is formed.

Electric vehicle batteries (capacity) are trending at 40 kWh that can run for the mid to late 200 km. This trend is due to the fact that compared to electric vehicles equipped with large-capacity batteries (over 60 kWh), the weight is about 20% lower, and the resulting power efficiency, weight reduction of various parts, and the ease of performance improvement such as output with high-efficiency motors and powertrains. In addition to this trend, the total capacity and specifications of the battery pack can be determined by algorithmizing the demand forecast of the electric vehicle itself.

In addition, the battery module (102) is discharged when power is supplied to the electric vehicle, and is recharged by receiving power from a power source or grid by the first power management unit (144) under control of the first battery management unit (142), which will be described in detail later.

In connection with the above, each of the lower module (110) and the stacked module (120) of the present invention is connected to the battery module (102) and measures voltage, current, and temperature to diagnose the safety status and the presence of a failure and control the temperature and battery cell balancing, and the first power management unit (144) connected to the power generation source or system, the load, and the battery module (102), and receives power from the power generation source or system to charge the battery module (102) and send the charged power to the load side, and the first battery management unit (142) and the first power management unit (144) are connected, and the first battery management unit (142) and the first power management unit (144) monitor and analyze the first battery management unit (142) and the first power management unit (144), control the first battery management unit (142) and the first power management unit (144), and provide charge/discharge information. It is configured to include a first energy storage system (140) including a first energy management unit (146).

The above first battery management unit (142) can monitor the battery module (102) and control charging and discharging.

The above first battery management unit (142) is connected to the battery module (102), is connected to a sensor that senses various states, and based on information detected from the sensor, maintains the voltage of the battery module (102) from falling below a certain voltage (discharge end voltage, etc.) and prevents charging above a certain voltage, and manages the battery module (102) in general by monitoring and controlling the state of charge (SOC: State Of Charge), voltage, current, temperature, etc. of the battery module (102).

Since the characteristics of each battery cell are not the same due to the manufacturing characteristics of battery cells, voltage differences may occur between batteries connected in parallel due to continuous charging and discharging. Battery balancing is very important for the life of the battery. For example, when a lithium-ion battery is overcharged, most of the active materials in the lithium-ion battery will react with other materials and the electrolyte, which may potentially damage the battery itself or even cause an explosion. In addition, when the battery is deeply discharged or continuously discharged, the battery may be short-circuited even when the terminal voltage is below a certain threshold called the cutoff voltage, which may cause the battery to change into an irreversible condition.

At this time, the first battery management unit (142) may be characterized by determining that the battery has a voltage imbalance if the voltage of the battery cell does not fall within the balance judgment range.

For example, the average or deviation of each battery cell's voltage or state of charge, etc., can be used as a judgment reference value, and a value between the judgment reference value and a predetermined tolerance value can be used as a balance judgment range, so that a battery that falls outside the balance judgment range can be judged as a battery cell with a voltage imbalance.

In addition, the cell balancing of the first battery management unit (142) may be characterized by determining a battery to be balanced, including some or all of the battery cells in which a voltage imbalance is detected.

In other words, not all battery cells with detected voltage imbalance are subject to balancing, and if there is a battery cell with detected voltage imbalance, the target battery for balancing can be determined. At this time, the target battery for balancing can be divided into a battery to be charged and a battery to be discharged. For example, if the average value of each battery voltage is used as the judgment reference value, and five batteries are connected in parallel, and the respective battery voltages are 210V, 220V, 220V, 225V, and 225V, and the predetermined tolerance value is 6V, the balance judgment range is 214 to 226V, and one 210V battery is included in the balance judgment range. At this time, if one 210V battery and two 225V batteries are connected in parallel and it is assumed that there is no current consumed by the resistance, all batteries become 220V, and all batteries are included in the balance judgment range. Here, the battery to be charged is a 210V battery, and the battery to be discharged is a 225V battery.

The above first power management unit (144) is connected to a power source or system, a load, and the above first battery management unit (142), and receives power from the power source or system to charge the battery module (), and sends the charged power to the load side.

In addition, when the lower module (110) or the stacked module (120) is stored in the lower part (300) or the stacked part (400), respectively, the first power management unit (144) is connected to the third power management unit (720) of the lower part (300) and the stacked part (400) to charge the battery module ().

The power system can be power generated from power generation facilities such as thermal power, hydro power, nuclear power, solar power, solar thermal power, wind power, and tidal power, power supplied from transmission/distribution facilities, household power (220 V), and industrial power (380 V).

The above first power management unit (144) is also referred to as including PMS (Power Management System) software.

The above first power management unit (144) converts direct current power generated from various power generation sources such as solar power into alternating current and controls it so that it can be used. In addition, it can control both charging and discharging directions and can adjust the voltage and frequency according to the purpose.

The above first power management unit (144) can use the grid power of AC-DC conversion for battery charging, can use DC-DC conversion for power conversion of renewable energy such as solar power, and can use DC-AC conversion for power transmission to the grid.

The above first power management unit (144) can enable monitoring of the BMS status of each unit, control quality of active power, reactive power, etc., measure voltage and connection, monitor operation status, and perform maximum point tracking control of renewable energy such as solar power.

The above first power management unit (144) can perform grid protection in the event of a power outage, control quality according to renewable power, perform standalone power generation using a battery in the event of a grid shutdown, and store log records in the event of a problem.

In order to perform these functions within the first energy storage system (140), it is desirable to enable organic communication with the first battery management unit (142) and the first energy management unit (146) to be described in detail later.

Additionally, it is desirable to design it so that users can monitor it through HMI (Human Machine Interface), etc.

The first energy management unit (146) is connected to the first battery management unit (142) and the first power management unit (144), monitors and analyzes the first battery management unit (142) and the first power management unit (144), controls the first battery management unit (142) and the first power management unit (144), and provides charging and discharging information.

The above first energy management unit (146) is an energy management solution that controls and monitors the operation of the first energy storage system (140) as a control tower of the first energy storage system (140). It can provide a system that can monitor and analyze the first energy storage system (140) in real time through sensors and measuring equipment of the first energy storage system (140), including the first battery management unit (142), and simultaneously perform monitoring and control through a communication network.

The above first energy management unit (146) can be responsible for functions such as simple functions such as controlling charging and discharging times, predicting demand and supply by algorithmizing power consumption pattern information and power price information provided through power demand prediction elements and deep learning models, and creating, operating, and managing an operation plan for an energy storage system through this.

The above first energy storage system (140) can easily monitor the charging/discharging information provided through the first energy management unit (146) and control the charging station.

In addition, since it is compatible with solar power sources, the first energy storage system (140) can also be considered for linkage with renewable energy providers.

It goes without saying that the above first energy storage system (140) can be designed by taking into consideration AC low-voltage panels, DC distribution panels, reverse power meter cells, maximum demand power meters, meters, and various protective equipment.

The control module (130), which is the main component of the present invention,

It is laminated and connected to the battery module (102) of the laminated module (120) by being laminated and connected on the upper part of the laminated module (120), and is stored in the control unit (500) to be described in detail later so that the internal battery for normal operation is charged, and when a request signal from the user's terminal, i.e. a request signal for a charging amount required for an electric vehicle or a charging amount appropriate for the price, is received by the control unit (600) to be described in detail later, it moves from the laminated unit (400) to the assembly rail (200) to be described in detail later so that the charging module (100) is assembled and completed.

That is, the control module (130) of the present invention is laminated and connected at the bottom to the top of the laminated module (120) located at the top in a state where at least one laminated module (120) is laminated.

In addition, the control module (130) of the present invention is configured to include a plurality of coupling protrusions (131) that are formed protrudingly on the lower surface, but are formed protrudingly at a position adjacent to a corner so as to correspond to a plurality of coupling grooves (123) formed on the upper surface of the stacking module (120) described above.

The above-mentioned joining projection (131) is formed to correspond to the joining groove (123) of the previously described stacking module (120), thereby enabling stacking and joining to the upper portion of the stacking module (120).

At this time, it is preferable that the plurality of coupling protrusions (131) are formed in a structure that allows the battery modules (102) of the stacked module (120) to be electrically connected. Any structure used in the past may be used. For example, the coupling protrusions (131) are configured to include a first connection terminal (not shown in the drawing) formed in the center and connected to a second connection terminal formed in the coupling groove (123) of the stacked module (120).

In addition, it is preferable that the protrusion length of the above-mentioned coupling projection (121) be formed to be greater than the depth of the above-mentioned coupling groove (123). This is to enable the stacking module (120) to be moved upward and stacked by the moving part (320) to be described in detail later.

The control module (130) of the present invention is configured to include a second energy storage system (134) including a second battery management unit (134a), a second power management unit (134b), and a second energy management unit (134c) so that power of the battery module (102) installed inside the lower module (110) and at least one stacked module (120) described above can be smoothly supplied to the electric vehicle.

The above second battery management unit (134a) is connected to the above first battery management unit (142) and diagnoses the safety status and the presence of a failure through the voltage, current, and temperature of the laminated lower module (110) and at least one laminated module (120), and controls the temperature and balancing of the laminated lower module (110) and at least one laminated module (120).

At this time, the second battery management unit (134a) treats each of the lower module (110) or the stacked module (120) as one battery module and controls them through the first battery management unit (142). Since this control has the same role as the first battery management unit (142), a detailed description will be based on the description of the first battery management unit (142).

The second power management unit (134b) is connected to the first power management unit (144) and controls the first power management unit (144) so that the charged power of the lower module (110) and the stacked module (120) can be sent to the load side.

This second power management unit (134b) also treats each of the lower module (110) or the stacked module (120) as one battery module and controls it through the first power management unit (144). Since this control has the same role as the first power management unit (144), a detailed description will be given based on the description of the first power management unit (144).

That is, the second energy management unit (134c) also treats the lower module (110) or the stacked module (120) as one battery module and controls them through the second battery management unit (134a) and the second energy management unit (134c). Since this control has the same role as the first energy management unit (146), a detailed description will be based on the description of the first energy management unit (146).

In addition, the control module (130) of the present invention is connected to the first power management unit (144) and the first energy management unit (146), and is configured to include a power supply unit (132) that supplies power to the electric vehicle.

The power supply unit (132) above is a unit connected to an electric vehicle for charging the electric vehicle, and the power supply unit (132) includes a charging socket (not shown in the drawing) and a connector (not shown in the drawing), and the connector includes a socket connection unit and a charging port connection unit, wherein the socket connection unit is formed to be electrically connected to the electrical contact of the charging socket according to the electric vehicle charging connector specifications of the charging port connection unit.

At this time, any power supply unit (132) that has been used in the past may be used, so a detailed description will be omitted.

Additionally, there are two main charging methods for electric vehicles: slow charging and rapid charging.

The above slow charging method uses 220V AC power and converts it to DC through the OBC (On Board Charger) to charge the battery. The full charging time is usually about 4 to 5 hours (based on the Ioniq electric vehicle).

The above rapid charging method charges the high-voltage battery directly using high-voltage DC without going through the OBC, and the normal full charging time is around 25 minutes (based on the Ioniq electric vehicle, 100kW charger).

That is, the control module (130) of the present invention can select a charging method for an electric vehicle and charge it through the second energy storage system (134).

Thereafter, when the front surface of the sliding part (114) comes into contact with the contact sensor (122a) of the sliding home (122), the control unit (600) controls the lifting motor (125) to lower the fixed plate (124) so that the lower portion of the fixed plate (124) enters the fixed home (116), thereby allowing one stacked module (120) to be stacked and connected to the upper portion of the lower module (110).

To explain further, the storage unit (310) is configured to include a pair of front and rear rails (312) installed in the front and rear directions on one side and the other side of the partitioned storage space, respectively, and two pairs of lifting rails (314) installed in the vertical direction on one side and the other side between the partitioned storage space in the front and rear, but positioned between the front and rear rails (312).

That is, the above-mentioned elevator rails (314) are installed in pairs on one side between the storage space divided into the front and rear, and in pairs on the other side between the storage space divided into the front and rear, for a total of two pairs.

At this time, the forward/backward moving plate (321) is installed so that one side and the other side can move forward/backward on the side rail, and the storage box (310) is configured to include a plurality of forward/backward motors (316) controlled by a control unit (600) to be described in detail later, and accordingly, the forward/backward moving plate (321) is moved laterally by the forward/backward motors (316).

In addition, the above-described lifting and lateral moving plate (322) is configured to include a support frame (322a) installed so that one side and the other side can move up and down on the lifting rail (314), a lateral frame (322b) provided with a plurality of second support bars (322b-1) formed in a fork shape so that they can move laterally on the inside of the support frame (322a) and are formed to be interlaced with the first support bars (321a) of the forward-backward moving plate (321) on the inside front and rear, and a lateral cylinder (322c) installed on one side of the inside of the support frame (322a) to move the lateral frame (322b) laterally.

In addition, the movement of the lower module (110) or the stacking module (120) or the control module (130) is performed by the control unit (600) which will be described in detail later, the forward/reverse motor (316), the lifting motor, and the lateral cylinder (322c), so that the lower module (110) or the stacking module (120) or the control module (130) stored in one of the storage spaces of the storage box (310) is positioned between the storage spaces divided forward and backward by the forward/reverse moving plate (321) installed in the storage space, and the lifting and lateral moving plate (322) is raised, but is raised higher than the forward/reverse moving plate (321) so that the lower module (110) or the stacking module (120) or the control module (130) supported by the forward/reverse moving plate (321) is positioned above the lifting and lateral moving plate (322), When the above forward/backward moving plate (321) is moved to the storage space, i.e., returned to the original position, the above lifting and lateral moving plate (322) is raised to a height for stacking and the lower module (110) or stacking module (120) or control module (130) is moved to the upper part of the assembly rail (200) by the above lateral cylinder (322c).

Thereafter, the lifting and lateral moving plate (322) places the lower module (110) or the stacking module (120) or the control module (130) on the upper side of the assembly rail (200), on the upper side of the lower module (110), or on the upper side of the stacking module (120), and then moves toward the storage box (310) by the lateral cylinder (322c) so that the lower module (110), the stacking module (120), and the control module (130) are stacked and combined.
