Description

ELECTRIC AND THERMAL HYBRID RECHARGE DEVICE FOR A DESCRIPTION BATTERY

TECHNICAL AREA

The present invention relates to solutions for recharging a battery, in particular a high power battery, making it possible to limit the increase in temperature of the battery.

The invention finds various applications in many fields, and in particular in the case of the use of batteries with high constraints on the weight of the battery and / or requiring high powers in use or in recharging, as for example in the automotive field, in particular due to a rapid charge of the vehicle, or in the aeronautical field, in particular due to a rapid charge and a strong need for supply of electric current during takeoff, for example.

The invention thus provides a hybrid device for recharging a battery, an electric battery using this recharging device, an assembly comprising such a recharging device and such a battery, as well as an associated recharging method.

PRIOR STATE OF THE ART

When using a battery with high charge and discharge rates, it tends to get very hot. However, too high a temperature can cause a reduction in the performance of the battery, or even worse, a stopping of the latter.

Consequently, it is desirable to be able to reduce the temperature level when using a high power battery so as not to reach the alarm thresholds, and therefore a shutdown of the latter.

There are oil-cooled batteries on the market, embedding a cold group in the battery, making it possible to reduce the temperature increase during its use. However, these systems have the major drawback of the weight of the cooling unit, making it possible to limit the increase in temperature, becoming very detrimental in an on-board system, such as a means of transport such as a car, an airplane, a truck, leading to a decrease in autonomy.

Consequently, there remains a need to be able to manage the temperature of a battery, and in particular to be able to cool it, while retaining properties of optimal performance, reduced weight and limited bulk of the battery.

STATEMENT OF THE INVENTION

The invention therefore aims to at least partially remedy the needs mentioned above and the drawbacks relating to the embodiments of the prior art.

The subject of the invention is therefore, according to one of its aspects, a hybrid, electric and thermal charging device, for a battery, in particular a high power battery, characterized in that it comprises:

- an electric battery charging module, comprising a positive terminal and a negative terminal for the circulation of an electric current in the battery,

a thermal control module of the battery, comprising an inlet and an outlet for heat transfer fluid for the circulation of a heat transfer fluid in the battery so as to control the temperature of the battery.

The recharging device according to the invention may also include one or more of the following characteristics taken in isolation or according to any possible technical combination.

The recharging device can take the form of a recharging terminal to which a battery is electrically and fluidly connected.

Advantageously, the recharging device can allow locking of the connection between the battery and the recharging device, for example by means of screws or a clip. In particular, in order to avoid any risk of accidental disconnection, the unlocking of the connection between battery and recharging device can be controlled by the recharging device capable of carrying out the checks necessary to ensure disconnection under conditions of safety and cleanliness ideal. This function of the recharging device for locking the connection between the battery and the recharging device plays in particular a role in terms of user safety in view, for example, of the risks of electric arcs or of projection of heat transfer fluid, among others.

The thermal control module can advantageously include means for permanently determining the temperature of the heat transfer fluid circulating in the battery, and in particular the temperature of the battery.

In addition, the thermal control module may be able to lower, maintain or increase the temperature of the heat transfer fluid circulating in the battery, and in particular the temperature of the battery, in particular as a function of the determination of the temperature of the heat transfer fluid or of the drums.

The heat transfer fluid can be chosen from: air, water, deionized water, glycol water and / or oil, among others.

Depending on the choice of heat transfer fluid, special precautions may be provided related to its use, for example when the heat transfer fluid presents risks of soiling, toxicity, corrosion, too high viscosity, electrical conduction unfavorable to the electrical insulation, condensation, among others.

The hybrid charging device may include a hybrid connector, combining an electrical connection and a fluid connection, for the connection of the charging device to the battery.

The hybrid connector of the device can group the positive and negative terminals of the electrical load module, and the inlet and outlet of heat transfer fluid from the thermal control module.

In addition, a user must be able to stop the charge in progress if he wants to use the battery, even if it is not fully charged. Thus, the recharging device 1 can advantageously include a device for manually cutting off the charge and making the battery available.

In addition, the invention also relates, according to another of its aspects, to an electric battery, in particular a high-power battery, characterized in that it comprises a fluidic circuit for circulation of a heat-transfer fluid allowing the control of the temperature of the battery, in particular a fluid circuit capable of being fluidly connected to the thermal control module of the recharging device as defined above.

The battery may include a positive port and a negative port for the circulation of an electric current for recharging the battery, in particular coming from the electric recharging module of the recharging device as defined above.

The battery can also include an inlet port and an outlet port for a heat transfer fluid, in particular from the thermal control module of the recharging device as defined above, for controlling the temperature of the battery.

In addition, the heat transfer fluid circulating in the battery can be passive, the battery being devoid of a system for regulating the temperature of the heat transfer fluid, and in particular for cooling the heat transfer fluid, which preferentially does not circulate during the charging of the battery. .

The battery can also include a hybrid connector, combining an electrical connection and a fluid connection, for connecting the battery to the recharging device.

The hybrid connector of the battery can group the positive port and the negative port, and the input port and the output port of the heat transfer fluid of the battery.

In addition, the hybrid connector of the battery may include a non-return valve at the inlet port and / or the outlet port so as to avoid having a heat transfer fluid leak, in particular when the battery is disconnected.

Furthermore, the hybrid connector of the battery or of the recharging device may include an element for recovering the temperature of the battery, for example a temperature sensor.

In addition, the hybrid connector of the battery or of the recharging device may include a polarization device for assistance with the fluidic and electrical connection.

By way of example, such a hybrid connector for the charging device or the battery can be chosen from the range of CombiTac connectors sold by the company Stâubli. More generally, the type of hybrid connector can be chosen according to the needs of the user.

Furthermore, the subject of the invention is also, according to another of its aspects, an assembly, characterized in that it comprises:

- a recharging device as defined above, and

- a battery as defined above.

The assembly may include a device for purging the fluidic circuit of heat transfer fluid.

Since the heat transfer fluid is potentially dirty for a user, such a device for purging the fluid circuit before the connection and / or disconnection operations may prove necessary. Such a purge can be carried out by the recharging device before unlocking the recharging device.

Alternatively, the fluidic connections of the fluidic circuit can be made using the cleanest possible opening connectors.

In addition, the invention also relates, according to another of its aspects, to a method for recharging a battery, in particular a high-power battery, in particular a battery as defined above, characterized in that it is set implemented by means of a recharging device as defined above, and in that it comprises the step of effecting the electric recharging of the battery while controlling the temperature of the battery by means of the circulation of the fluid coolant.

DETAILED PRESENTATION OF PARTICULAR EMBODIMENTS

The present invention aims to manage the temperature of an electric battery 2 during the charging thereof by means of a heat transfer fluid FC circulating in the battery 2. The invention also aims to be able to manage the initial temperature at the end charging the battery 2, namely in particular making it as low as possible, in order to anticipate the subsequent use of the battery 2 in discharge mode, during which the battery 2 will usually experience a rise in temperature.

As will be explained below, a user may have the choice, when starting the charging of the battery 2, to carry out a slow charging at reduced current having the effect of limiting heating of the battery 2 and therefore the need to cooling will be less important, or to carry out a rapid charge at high charging current having the effect of overheating the battery 2. In this case, the need for cooling turns out to be necessary in order to have the battery 2 available quickly and therefore continuity of service for the user with the best possible performance.

Referring to Figure 1, there is shown an example of assembly 10 comprising a charging device 1 hybrid, electric and thermal, and an electric battery 2 according to the invention.

According to the invention, the recharging device 1 comprises an electric recharging module 3 of the battery 2. This electric recharging module 3 is for example a high power charger to allow the charging of a high power battery 2. It includes a positive terminal B + and a negative terminal B- for the circulation of an electric current in the battery 2.

The electric battery 2 comprises a positive port P +, connected to the positive terminal B + of the recharging device 1, and a negative port P-, connected to the negative terminal B-of the recharging device 1.

Thus, an electric circuit is created between the electric recharging module 3 of the recharging device 1 and the electric battery 2 which allows the circulation of an electric current for recharging the battery 2 coming from the electric recharging module 3.

Furthermore, the recharging device 1 also comprises a thermal control module 4 of the battery 2, constituting in particular a cold group. This thermal control module 4 will make it possible to adjust the temperature of the heat transfer fluid FC circulating in the battery 2 in order to manage the temperature of the latter, namely to lower, increase or maintain its temperature.

This thermal control module 4 more precisely comprises an input EF and an output SF of heat transfer fluid for the circulation of the heat transfer fluid FC in the battery 2.

Likewise, the battery 2 comprises a fluidic circuit for circulation of the heat transfer fluid FC, which is connected to the thermal control module 4 via an input port PE and an output port PS of the heat transfer fluid FC.

Thus, a fluid circuit is created between the thermal control module 4 of the recharging device 1 and the electric battery 2. This fluid circuit is distinct from the electric circuit and it allows the circulation of the heat transfer fluid FC in the battery 2 in order to be able to control its temperature.

Preferably, this fluid circuit is a low temperature fluid circuit making it possible to cool the battery 2 during charging and to limit the temperature rise as much as possible. In particular, the heat transfer fluid FC from the thermal control module 4 will be injected into the battery 2 during charging at low temperatures in order to manage the usual increase in temperature of the battery 2 during charging at high power.

In fact, advantageously, the thermal control module 4 includes means for permanent determination of the temperature of the battery 2. In addition, the thermal control module 4 is able to lower the temperature of the battery 2 if necessary. , as a function of the determined temperature of the battery 2. In other words, permanent knowledge of the temperature of the battery 2 allows the recharging device 1 to continuously adapt the cooling strategy, and therefore to optimize the charging phase and the maximum temperature not to be exceeded.

Advantageously, the heat transfer fluid FC will circulate inside the battery 2 to cool it as soon as it is connected to the hybrid charging device 1. This will then allow firstly to cool the battery 2 just used, and secondly to lower the temperature of the latter as much as possible during the recharging phase so that it can be used immediately after have finished recharging. The temperature of the battery 2 will therefore be lowered throughout the charging phase, and with the help of the thermal control module 4, the temperature of the heat transfer fluid FC within the battery 2 may be greatly reduced and will make it possible to limit the increase in temperature during future use.

Furthermore, in order not to change the habits of a user, for example in the case of a battery of an electric vehicle, the implementation of the charging device 1 according to the invention must be as transparent as possible for this user.

Also, advantageously, a hybrid connector 15, both electrical and thermal, is used to make the connection between battery 2 and recharging device 1.

FIG. 2 schematically illustrates a principle of a hybrid connector 15 which can be fitted to the charging device 1 or the battery 2. For this reason, in this figure 2, the elements of this connector 15 can be designated by elements of the charging device 1 or battery cells 2.

The user can therefore connect the charging device 1 with the battery 2 using such connectors 15. It should be noted that the charging device 1 and the battery 2 can each include such a hybrid connector 15. As a variant, only the recharging device 1 or only the battery 2 can comprise such a hybrid connector 15.

This hybrid connector 15 advantageously combines an electrical connection and a fluid connection. Thus, for the recharging device 1, it includes the positive terminal B + and the negative terminal B- of the electrical charge module 3, as well as the input EF and the output SF of heat transfer fluid from the thermal control module 4. Similarly , for the battery 2, it includes the positive port P + and the negative port P-, as well as the input port PE and the output port PS of heat transfer fluid FC of the battery 2.

To be able to ensure good cooling, the hybrid connector 15 can be provided to allow the passage of a large flow of heat transfer fluid FC in order to optimize the cooling of the battery 2. If necessary, the use of the pressure of the fluid FC coolant can allow the actuation of actuators, such as cylinders.

Advantageously, the positive P + and negative P- ports, as well as the positive B + and negative B- terminals, are provided to be able to withstand rapid charging of the battery 2. Thus, they can withstand high currents, and therefore have a low contact resistance, and in particular be able to withstand currents greater than 100A, or even 300 A, for rapid recharging with a power of the recharging device 1 greater than 45 kW. In addition, the recharging device 1 can supply a hundred kilowatts, such as for example a Tesla supercharger for a 114 kW, 368 V / 314 A car.

In addition, the PE inlet and PS outlet ports, as well as the EF inlet and SF outlet, of heat transfer fluid FC can allow a high circulation flow rate of the heat transfer fluid but not necessarily high pressure. In particular, the heat transfer fluid flow rate can be between 5 and 10 m ³ / h in order to ensure rapid renewal of the fluid and thus maximize the cooling function.

The hybrid connector 15 can also include one or more communication elements between the charging device 1 and the battery 2, for example a data bus, in particular of CAN type (for “Controller Area Network” in English). It is also possible to provide wireless communication between the device 1 and the battery 2, for example of the wiki or Bluetooth type. In this way, the hybrid connector 15 can be devoid of any data bus. For data protection, the wireless connection can then be made only during a recharging phase.

In addition, as can be seen in FIG. 2, the hybrid connector 15 may include an element 16 for recovering the temperature of the battery 2, and also a keying device 17 for assistance with the fluidic and electrical connection.

The presence of a keying device 17 can make it possible to avoid connection and / or locking errors.

Furthermore, FIG. 3 is a block diagram illustrating a sequence for stopping the charging of the battery 2 requested by a user.

Step A1 represents the current charge of the battery 2. Then, at time T1, a user requests that the charge be cut, for example by means of a stop button, a mobile telephone, a subscriber card, among others.

Then, during step A2, the electric charging circuit is cut, which implies at time T2 the end of the electric charge.

The circulation of the heat transfer fluid FC is then cut off during step A3, after which time T3 marks the circulation of the heat transfer fluid FC.

Step A4 then consists in carrying out a purge of the fluid circuit, so that at time T4, the purge is carried out and a disconnection of the battery 2 without risk of soiling is possible.

During step A5, the recharging device 1 is therefore disconnected from the battery 2 and at time T5, information is communicated to the user, for example by means of an indicator light, a voice message, a sound, etc., indicating that he can physically disconnect the battery 2.

Finally, step A6 consists in making the battery 2 fully or partially charged available.

FIG. 4 is also a block diagram which makes it possible to illustrate the sequence of steps implemented to charge the battery 2. FIG. 5 is a block diagram illustrating the charging sequence described by the continued with reference to Figure 4.

As shown in Figure 4, during step B1, the battery 2 is in an initial state. At time RI, recovery of the internal temperature of the battery 2 is carried out.

The rest of the process depends on the choice of the user. First of all, during step B2, the user chooses a slow charge of the battery 2. Then, step B6, described below with reference to FIG. 5, allows the launching of the sequence of charge with suitable electric current.

Following this step B6, the final steps B8, B10 and B11 allow respectively the end of the charge, the purging procedure of the fluid circuit and the possible disconnection of the battery 2.

However, during step B3, the user can on the contrary choose a rapid charge of the battery 2. Then, step B4 can allow him to enter the time at which he wishes to be able to recover the battery 2.

During step Q1, the recharging device 1 will examine whether charging is possible for the requested time. If it is not (case N in FIG. 4), the recharging device 1 proposes, during step B5, a possible schedule for the user, who decides either to cancel the procedure at time R2, or to validate the procedure at time R3. If charging is possible (case O in FIG. 4), then step B7 is launched aiming to start the charging sequence with the appropriate electric current. Steps B6 and B7 are the same and described below with reference to FIG. 5. Likewise, step B7 is extended by steps B8, B10 and B11 as described above.

It should also be noted that during step B9, a user can request the stopping of the charge in progress.

Referring to Figure 5, we now describe the charging sequence of a battery 2 incorporating the cooling function.

Thus, step DI corresponds to the initial state of the battery 2. At time PI, recovery of the internal temperature of the battery 2 is carried out.

From this flow three possible cases:

- Condition C1 provides that the temperature of the battery 2 is higher than the temperature of the heat transfer fluid FC, then step D2 provides for the charging of the battery 2 and the cooling;

- condition C2 provides that the temperature of the battery 2 is identical to the temperature of the heat transfer fluid FC, then step D3 provides for charging the battery 2 and maintaining the temperature;

- Condition C3 provides that the temperature of the battery 2 is lower than the temperature of the heat transfer fluid FC, then step D4 provides for charging the battery only.

At the end of steps D2, D3 and D4, the times P2 mark the end of the electrical charge.

There are then two possibilities in anticipation of discharging the battery 2:

- Condition C4 provides that the temperature of the battery 2 is higher than the temperature of the heat transfer fluid FC, so step D5 consists in cooling the battery. At the end of step D5, condition C6 requires checking whether the temperature of the battery 2 is less than or equal to the temperature of the heat transfer fluid FC. If this is the case, step D7 allows the cooling to stop;

- Condition C5 provides that the temperature of the battery 2 is less than or equal to the temperature of the heat transfer fluid, so step D6 consists of stopping the cooling.

The steps D7 and D6 are both followed by a time P3 signifying the end of the fluidic charge. During step D8, the battery 2 is then ready and available for use.

Advantageously, the recharging device 1 can take the decision to cool the battery 2 during charging but also to maintain the latter at a predetermined temperature for its future use.

For example, an ideal temperature at the end of charging can be equal to around 30 ° C but the battery 2 can still continue to offer continuity of service with a temperature close to 40 ° C.

For this, the recharging device 1 is able to maintain its heat transfer fluid at a certain temperature in order to be immediately operational as soon as the battery 2 is connected. It can then adapt its electric current and its cooling flow as a function of the temperature. of battery 2, namely in particular:

- a low current and a high cooling flow if the temperature of the battery 2 is higher than a target temperature;

- a nominal current and a nominal cooling flow if the battery 2 is at the target temperature;

A nominal current and a low cooling flow if the temperature of the battery 2 is lower than the target temperature.

Anyway, a user can decide at any time to stop charging the battery 2 to be able to use it immediately without obligation to wait for the end of the various steps described above.

Advantageously, the invention therefore makes it possible to be able to recharge an electric battery with a regulated temperature by means of the circulation of the heat transfer fluid.

The fact of using a separate recharging device rather than an on-board system for this temperature regulation provides numerous advantages. For example, it is possible to obtain a gain in mass and to increase the autonomy of the battery by controlling in particular the temperature of start of discharge. In addition, the principle of the invention allows the use of the same hybrid connector, electrical and fluid, to connect the charging device and the battery, which simplifies the use of the assembly for a user. In addition, it may be possible to control the starting time of the charging of the battery as a function of the desired charging time, but also the desired instant at strong discharge so as to control the temperature at the end of charging.

Furthermore, the invention makes it possible to limit the aging of the battery. Indeed, it is known that using or storing a battery at high temperatures shortens the life of the battery. Thus, in the application of rapid battery charges, it is common to have a temperature which increases sharply during charging. The invention thus provides a double benefit insofar as it allows rapid charging while limiting the aging of the battery.

In addition, it is possible to limit the downtime of the battery. The faster the battery is charged, the more the user can use it again. In addition, by continuously cooling it during charging, the user will have access to optimal performance immediately after charging, which is not necessarily the case during rapid charging without cooling due to the temperature increase. which limits battery performance.

Of course, the invention is not limited to the exemplary embodiments which have just been described previously. Various modifications can be made by those skilled in the art.

In particular, it should be noted that the battery charging strategy described above is rather suitable for a country whose climate is temperate, even hot, and therefore based on the principle that the battery should be cooled. However, the recharging device, capable of controlling the temperature of the battery, can also be provided to heat the battery, in particular if the latter is located in a country whose climate is cold. Indeed, battery manufacturers generally prohibit charging the batteries at a temperature below 0 ° C. In this case, the recharging device according to the invention can make it possible to heat the battery if the latter has a temperature below 0 ° C. and to maintain a sufficient temperature until the device is disconnected.
