Definitions
- One aspect of the invention relates to a method for monitoring the operation of module temperature sensors of a traction battery.
- the invention lies in the field of thermal monitoring of the modules of a traction battery, in particular of a vehicle traction battery.
- Electric or rechargeable hybrid vehicles are equipped with a traction battery.
- a traction battery is adapted to supply electric power to an electric traction machine of the vehicle and is adapted to be recharged by receiving electric power through a converter, a charging station or even a an electric traction machine during regenerative braking.
- the temperature of such a traction battery usually increases as a function of the solicitation of the latter in charging or discharging. When the stress is too great, thermal runaway of one of the modules in the battery can occur. Such thermal runaway then propagates to other adjacent modules.
- document FR-B1-3093028 discloses a method for managing an air conditioning circuit connected to a cooling circuit of a battery. According to this method, when the temperature of a traction battery exceeds a temperature threshold, a cooling circuit returns to its full operating potential to cool the traction battery of the vehicle as much as possible, down to a temperature threshold below from which the cooling circuit resumes normal operation.
- the temperature measurement may be erroneous.
- the value of the measured temperature of a traction battery can be suitable when the battery may actually be at too high an operating temperature.
- the cooling circuit retains its normal operation and does not effectively cool the battery which is overheated. This overheated battery is thus not sufficiently cooled and risks catching fire.
- the object of the invention is to overcome the drawbacks of the prior art by proposing a method for monitoring the operation of module temperature sensors of a traction battery making it possible to eliminate any risk of false temperature measurement.
- the invention thus relates, in its broadest sense, to a method for monitoring the operation of module temperature sensors of a traction battery of a vehicle, the modules each comprising a plurality of cells and a plurality of temperature sensors.
- the method according to this aspect of the invention comprises, for each module, the steps, executed by vehicle control means, of: receiving temperature values from the cells measured by the temperature sensors, determining differences in temperature of the temperature values received with respect to a reference temperature, if at least one of the determined temperature deviations is greater than a predetermined threshold, alerting a driver of a malfunction of at least one of the temperature sensors.
- This method thus makes it possible to guarantee the temperature information from the temperature sensors of the same module of the traction battery.
- this method makes it possible to mitigate any risk of thermal degradation of the modules of the traction battery and makes it possible to avoid any risk of thermal runaway of the traction battery which would be due to a false measurement. The safety of the passengers of the vehicle with respect to a risk of fire in the traction battery is thus improved.
- the method according to this aspect of the invention makes it possible to avoid false detection of a thermal runaway of the traction battery and therefore to evacuate the passengers from the vehicle unnecessarily.
- the method according to the invention may have one or more additional characteristics among the following, considered individually or according to all technically possible combinations.
- the temperature differences are determined as a percentage.
- the reference temperature is selected from the temperature values received and corresponds to a maximum temperature or a minimum temperature.
- the steps of receiving temperature values and determining temperature differences are repeated periodically, if at least one of the temperature differences determined within the module is greater than the predetermined threshold during a first predetermined period of time, the step of alerting comprises a sub-step of displaying a warning light on a console of the vehicle.
- the method includes a step of turning off the light when all the determined temperature differences of the module are, for a second predetermined period of time, below the predetermined threshold.
- the steps of receiving temperature values and determining temperature differences are repeated periodically, if at least two of the temperature differences determined within the module are greater than the predetermined threshold during a third predetermined period of time, the step of alerting comprises the sub-steps of: displaying a warning light on a console of the vehicle, and limiting a charge and a discharge of the traction battery.
- the method comprises a step of stopping the limitation of charging and discharging of the traction battery when, during a sixth predetermined period of time, at most a determined temperature difference is greater at the predetermined threshold.
- the steps of receiving temperature values and determining temperature differences are repeated periodically, if at least three of the temperature differences determined within the module are greater than the predetermined threshold during a seventh predetermined period of time, the step of alerting comprises the sub-steps of: displaying a stop light on a console of the vehicle; prohibit charging and discharging of the traction battery.
- the method comprises the steps of: controlling electrical insulation of the traction battery vis-à-vis a high-voltage network of the vehicle; actively discharge the vehicle's high-voltage network.
- the method comprises the steps of: turning off the stop indicator of the vehicle ; stop the ban on charging and discharging the traction battery.

- the method 100 for monitoring the operation of temperature sensors 4 of modules 2 of a traction battery 1 of a vehicle 5 comprises, for each module 2, a step executed for example by means of the battery control system 10 of receiving 101 temperature values of the cells 3 measured by the temperature sensors 4.
- each temperature sensor 4 transmits a value of a representative temperature the temperature of the two cells 3 to which it is connected.
- the method 100 further comprises a step, executed for example by means of the battery control system 10, of determining 102 temperature deviations of the temperature values received with respect to a reference temperature.
- the temperature differences are determined as a percentage.
- the reference temperature can be selected from among the temperature values received and corresponds to a maximum temperature or a minimum temperature of these temperature values received.
- the battery control system 10 selects the maximum temperature of the six temperature values received, the six temperature values having been transmitted by the six temperature sensors 4 of a module n.

- the method 100 includes a step of alerting 103 a driver of the vehicle 5 of a malfunction of at least one of the temperature sensors 4.
- each percentage of temperature difference E1%, E2%, E3%, E4%, E5%, and E6% of the six temperature items of the same module n is compared to the predetermined threshold.
- the predetermined threshold can be between 5% and 15%, typically 10%.
- the control system battery 10 sets up an alert when a temperature difference E1%, E2%, E3%, E4%, E5%, or E6% is greater than 10% in the same module. It is understood that the aforementioned steps are performed for each of the modules 2 of the traction battery 1.
- the steps of receiving 101 temperature values and determining 102 temperature differences are repeated periodically.
- the determination of the temperature differences E1%, E2%, E3%, E4%, E5%, and E6% of the temperature values Tn1, Tn2, Tn3, Tn4, Tn5 and Tn6 received with respect to a reference temperature is carried out periodically according to a predetermined reiteration period between the moment when the driver switched on the ignition and the moment when the driver switched off the ignition of the vehicle 5.
- This predetermined reiteration period can for example be between 500 and 1500 milliseconds, typically 1000 milliseconds.
- the battery control system 10 determines the temperature differences of the six sensors of the same module n every 1000 milliseconds.
- the step of alerting 103 includes a sub-step of displaying 104 an indicator light on a console of the vehicle 5.
- This first predetermined period of time can for example be between 2000 and 4000 milliseconds, typically 3000 milliseconds .
- the sub-step of displaying 104 an indicator light on a console of the vehicle 5, consists, for the battery control system 10, in transmitting a request to the vehicle control unit 9 to drive a warning light display to alert the driver.
- the vehicle control unit 9 then drives a display of the warning light to alert the driver.
- the method 100 comprises a step of recording 105 a first malfunction code.
- This first malfunction code 105 reflects that one of the temperature deviations E1%, E2%, E3%, E4%, E5% or E6% determined is too great and that consequently one of the temperature sensors 4 is faulty.
- the battery control system 10 can record the first malfunction code in its ROM to indicate to the after-sales service the source of the malfunction.
- the method 100 further comprises a step, executed for example by means of the battery control system 10, of turning off 106 the light when all the temperature differences E1%, E2%, E3%, E4%, E5% and E6% determined of the modulus n are, for a second predetermined period of time, lower than the predetermined threshold of 10% in the example described.
- This second predetermined period of time can for example be between 500 and 1500 milliseconds, typically 1000 milliseconds.
- the step of alerting 103 comprises the sub-steps of: displaying 107 a light on the console of the vehicle 5, and limiting 108 charging and discharging of the traction battery 1 .
- This third predetermined period of time can for example be between 2000 and 4000 milliseconds, typically 3000 milliseconds.
- the light reflects that two determined temperature differences are too great and that consequently two temperature sensors 4 are faulty.
- the light may be a service light indicating to the driver that a performance limitation is in place and prompting the driver to carry out a diagnosis at the garage.
- the sub-step of displaying 107 an indicator light on a console of the vehicle 5, consists, for the battery control system 10, in transmitting a request to the vehicle control unit 9 drive an indicator light display to alert the driver.
- the step of limiting 108 the charging and discharging of the traction battery 1, executed for example by means of the battery control system 10, consists of: when the vehicle 5 is in driving mode, limiting the electric power supplied by the traction battery 1 to the electric traction machine 6 of the vehicle 5 to a predetermined machine power, for example between 8 and 9 kW, typically 8.5 kW; the limitation being carried out over a fourth predetermined period of time, for example between 50 and 70 seconds, typically 60 seconds; when the vehicle 5 is in regenerative braking mode, limiting the electrical power supplied to the traction battery 1 during regenerative braking to a predetermined battery power, for example between 8 and 9 kW, typically 8.5 kW; the limitation being carried out over a fifth pre
- the limitation of the electric power supplied by the traction battery 1 to the electric traction machine 6 of the vehicle 5 to a predetermined machine power and the limitation of the electric power supplied to the battery of traction 1 during regenerative braking at a predetermined battery power are performed linearly.
- the method 100 comprises a step of recording 109 a second malfunction code.
- This second malfunction code reflects that two determined temperature deviations are too large and therefore two temperature sensors 4 of a module n are faulty.
- the battery control system 10 can save the second malfunction code in its ROM to indicate to the after-sales service the source of the malfunction.
- the method 100 comprises a step, executed for example by means of the battery control system 10, of stopping 110 the charging and discharging limitation of the traction battery 1 when, during a sixth predetermined period of time, at most a determined temperature difference is greater than the predetermined threshold.
- This sixth predetermined period of time can for example be between 500 and 1500 milliseconds, typically 1000 milliseconds.

- the step of alerting 103 comprises the sub-steps of:
- Display 111 a stop light on the vehicle console 5, and prohibit 112 charging and discharging of the traction battery 1 .
- This seventh predetermined period of time can for example be between 2000 and 4000 milliseconds, typically 3000 milliseconds.
- the sub-step of displaying 111 a stop light on a console of the vehicle 5, consists, for the battery control system 10, in transmitting a request to the vehicle control 9 to drive a stop light display to alert the driver.
- the stop light reflects that three determined temperature differences are too great and that consequently three of the six temperature sensors 4 of a module n are faulty.
- the stop light may be a stop light.
- the step of prohibiting 112 the charging and discharging of the traction battery 1 is carried out by means of the battery control system 10 and consists of: when the vehicle 5 is in mode rolling, prohibit the electric power supplied by the traction battery 1 to the electric traction machine 6, the prohibition being carried out over an eighth predetermined period of time, for example between 50 and 70 seconds, typically 60 seconds in our example; when the vehicle 5 is in regenerative braking mode, prohibiting the electrical power supplied to the traction battery 1 during regenerative braking, the prohibition being carried out over a ninth predetermined period of time, for example between 50 and 70 seconds, typically 60 seconds in our example; and when the vehicle 5 is in charging mode, prohibit the charging current of the traction battery 1.
- the prohibition of the electric power supplied by the traction battery 1 to the electric traction machine 6 of the vehicle 5 and the prohibition of the electric power supplied to the traction battery 1 during regenerative braking are carried out in a linear fashion.
- the method 100 comprises a step of recording 113 a third malfunction code.
- This third malfunction code reflects that three of the six temperature deviations determined are too large and therefore three of the six temperature sensors 4 of the same module have failed.
- the battery control system 10 can store the third malfunction code in its ROM to indicate to the after-sales service the source of the malfunction.
- the method 100 further comprises the steps of
- Control 114 via the battery control system 10, an electrical isolation of the traction battery 1 vis-à-vis a high voltage network of the vehicle 5, this electrical isolation being able to be achieved, for example, by opening contactors of insulation which link the traction battery 1 to the high voltage network (not shown) of the vehicle 5; Operate 115, via the vehicle control unit 9, an active discharge of the high voltage network of the vehicle 5.
- This step of operating 15 an active discharge of the high voltage network can be carried out at the end of a predetermined duration, by example between 30 and 90 seconds, typically 60 seconds, counted from the triggering of the step of controlling 114 an electrical insulation of the traction battery 1 .
- these isolation contactors can be formed by: a first contactor connected to a positive output of the traction battery 1 and a positive input of the electric traction machine 6, of the converter 7 as well as at a charging station (not shown); a second contactor connected to a negative output of the traction battery 1 and to a negative input of the electric traction machine 6, of the converter 7 as well as to the charging station.
- These contactors are circuit breaker type contactors: when they are closed, the current flows from the traction battery 1 to the electrical components of the vehicle 5, in other words the current can flow in the high voltage network of the vehicle 5 ; when they are open, the traction battery 1 is electrically isolated from the high voltage network of the vehicle 5.
- the traction battery 1 is electrically isolated and is no longer electrically stressed.
- active discharge of the high voltage network is meant the fact of eliminating the voltage residual present in the high voltage network.
- this voltage residual can be transformed into heat in the electric traction machine 6 as well as in the converter 7.
- the residual voltage of the high voltage network is thus reduced from 400V to less than 60V. This residual voltage is thus eliminated between the insulation contactors and the electric traction machine 6, the insulation contactors and the converter 7 as well as between the insulation contactors and the charging station.
- the method 100 further comprises the steps executed for example by means of the battery monitoring system 10 of: turning off 116 the stop light of the vehicle 5; stop 117 prohibition of charging and discharging traction battery 1.
- This tenth predetermined period of time can for example be between 500 and 1500 milliseconds, typically 1000 milliseconds.
- the step of stopping 117 the prohibition of charging and discharging of the traction battery 1 consists of: when the vehicle 5 is in driving mode, stopping the prohibition of electric power supplied by the traction battery 1 to the electric traction machine 6, when the vehicle 5 is in regenerative braking mode, stopping the prohibition of electric power supplied to the traction battery 1 during regenerative braking; or when the vehicle 5 is in charging mode, stop the prohibition of the charging current of the traction battery 1 .
