Description

Technical Field

[0001] The invention relates to the field of vehicle-mounted starting batteries, and in particular to detection and control of starting batteries when a vehicle is started. Background Art

[0002] Traditionally, lead-acid batteries are used for starting batteries in cars. The charging process of car batteries usually includes two stages: main charging and floating charging. For lead-acid batteries, the main charging method is mainly adopted during the initial charging. After the voltage reaches the rated value (such as 28V), it will switch to floating charging mode. As described in the patent CN114701510A entitled "A method for detecting battery faults, ECU, system and vehicle", the vehicle ECU will collect the voltage at both ends of the battery to determine whether the battery is faulty. In actual applications, when the ECU detects that the voltage at both ends of the battery is higher than a specific threshold (such as 28V) before starting, the ECU enters the overvoltage protection state, prohibiting the engine from starting, thereby prohibiting the generator from charging the battery to avoid battery overcharging.

[0003] In the process of replacing lead-acid batteries with lithium-ion starting batteries, because the existing lithium-ion starting batteries (generally using lithium iron phosphate batteries or sodium-ion batteries) have a high single-cell voltage platform (such as a lithium iron phosphate battery platform voltage of 3.2V, a single-cell overcharge protection voltage of 3.6V or above) and there is a load dump phenomenon, when a battery pack of 8 lithium iron phosphate batteries is used, the total voltage can reach 28.8V after the battery pack is fully charged. In actual applications, the total voltage of the lithium-ion starting battery exceeds the protection threshold (such as 28V) detected by the ECU, resulting in the ECU detecting overvoltage protection and the inability to ignite and start the engine. At this time, the battery pack voltage can only be manually discharged to reduce it.

[0004] Therefore, there is an urgent need for a starting battery detection control method and device applicable to lithium batteries that can solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a starting battery detection control method, device and vehicle starting method, so as to reduce the probability of triggering ECU overvoltage protection when the vehicle is started and achieve the effect of stable starting.

[0006] In order to achieve the above-mentioned object, the present invention provides a starting battery detection control method, comprising: connecting a unidirectionally conductive step-down branch in parallel to a charging switch of a starting battery, wherein the conduction direction of the step-down branch is opposite to the charging direction; controlling the charging switch of the starting battery to be turned on when a vehicle is about to start; detecting the total voltage of the starting battery, and comparing the total voltage of the starting battery with a starting limit threshold when the vehicle is started; when the total voltage of the starting battery exceeds the starting limit threshold, controlling the charging switch to be disconnected so that the step-down branch again lowers the output voltage of the starting battery based on the total voltage, and the vehicle continues to be started; when the output voltage of the starting battery does not exceed the starting limit threshold, the vehicle continues to be started.

[0007] Preferably, the single cell voltage of each cell in the starting battery, the total voltage of the starting battery, and the discharge current value of the starting battery are detected in real time, and the discharge current value is compared with the discharge detection threshold to determine whether the starting battery is in a discharge state. When the starting battery is not in a discharge state, and when any of the single cell voltages is greater than or equal to the overcharge protection threshold and the total voltage of the starting battery is greater than or equal to the full charge protection threshold, the charging switch is disconnected. When the starting battery of the present invention is charged and discharged, the total voltage of the starting battery is controlled below the starting limit threshold, thereby reducing the probability that the total voltage of the starting battery is greater than the starting limit threshold when the vehicle is started. Furthermore, when the starting battery is not in a discharge state, the scheme performs overvoltage protection to prevent the charging switch from being turned off in the discharge state from affecting the discharge, generating a large amount of heat, and damaging the components of the charging and discharging circuit.

[0008] Specifically, the charging switch is turned on immediately when the discharge current value is greater than or equal to the discharge detection threshold, the single cell voltage is less than or equal to the overcharge recovery threshold, and the total voltage is less than or equal to the charging recovery threshold, the overcharge recovery threshold is less than the overcharge protection threshold, and the charging recovery threshold is less than the full charge protection threshold.

[0009] Specifically, the overcharge protection threshold is 3.6V, the overcharge recovery threshold is 3.4V, the full charge protection threshold is 28V, the charge recovery threshold is 27.8V, and the discharge detection threshold is greater than or equal to 1A and less than or equal to 10A.

[0010] Specifically, when the vehicle is started, the charging switch is turned on after the discharge current value is greater than or equal to the discharge detection threshold and lasts for a first period of time. After the starting battery starts to discharge and continues for a period of time, the total voltage of the starting battery will decrease to a range less than or equal to the starting limit threshold, and will continue to decrease. At this time, there is no need to detect the total voltage and single cell voltage of the starting battery, and the charging switch can be turned on directly, thereby improving the timeliness of the charging switch on while ensuring a certain degree of safety.

[0011] The first duration is 2 seconds. Of course, the first duration can also be selected as other values ​​according to the setting needs.

[0012] Preferably, the charging switch is a MOS tube or a relay switch, and the starting battery is a lithium battery.

[0013] Preferably, the voltage-dropping branch is composed of a diode or a plurality of diodes connected in parallel or a diode and a voltage-dropping resistor connected in series.

[0014] The present invention also provides a starting battery detection control device, comprising a processor, a memory, one or more programs and a unidirectional step-down branch, wherein the unidirectional step-down branch is connected in parallel to the charging switch of the starting battery, and the conduction direction of the step-down branch is opposite to the charging direction; the one or more programs are stored in the memory and are configured to be executed by one or more processors, and the programs include instructions for executing the starting battery detection control method as described above.

[0015] The present invention also provides a vehicle starting method, comprising: connecting a unidirectionally conducting step-down branch in parallel to a charging switch of a starting battery, wherein the conduction direction of the step-down branch is opposite to the charging direction; activating a vehicle ECU unit using a vehicle key; performing a starting battery detection, wherein the starting battery detection is the starting battery detection control method as described above; continuing to start the vehicle comprises: detecting the output voltage of the starting battery, determining whether the starting battery output voltage is less than or equal to the starting limit threshold, and if so, allowing ignition to start the engine, and otherwise prohibiting ignition to start the engine.

[0016] The present invention also provides a vehicle starting control system, comprising a starting battery, a battery management module, a current detection circuit, a discharge switch and a charging switch, wherein the current detection circuit detects the charging current and the discharging current of the starting battery, the battery management module collects and obtains the single cell voltage and the total voltage of the starting battery, obtains the charging current and the discharging current detected by the current detection circuit, and controls the on-off action of the discharge switch and the charging switch, and a unidirectionally conducting step-down branch is connected in parallel to the charging switch, and the conduction direction of the step-down branch is opposite to the charging direction; the battery management module comprises a processor, a memory and one or more programs, wherein the one or more programs are stored in the memory and are configured to be executed by the processor, and the program comprises instructions for executing the vehicle starting method as described above.

[0017] Compared with the prior art, the present invention connects a unidirectional buck branch in parallel at the charging switch. After receiving the start command, the charging switch is first controlled to be turned on to prevent the current passing through the buck branch from being too large during startup, causing the unidirectional conductive element of the buck branch to overheat; then the total voltage of the starting battery is detected. When the total voltage of the starting battery exceeds the starting limit threshold, a fault signal is not output to allow manual discharge to consume electricity, but the charging switch is turned off, so that the unidirectional buck branch consumes part of the voltage, so that the output voltage of the starting battery is pulled down, reducing the probability of triggering the ECU overvoltage protection when the vehicle is started, achieving stable startup efficiency, simple control and low cost, better starting effect, and improving the starting effect, flexibility and convenience of the lithium-ion starting battery.

[0022] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0023] refer to Figure 1 The present invention discloses a vehicle starting system, including a starting battery 30, a battery management module 10, a current detection circuit 23, a discharge switch 22 and a charging switch 21, wherein the current detection circuit 23 detects the charging current and the discharging current of the starting battery 30, the battery management module 10 collects and obtains the single cell voltage and the total voltage of the starting battery 30, obtains the charging current and the discharging current collected by the current detection circuit 23, and controls the on-off action of the discharge switch 22 and the charging switch 21, and the charging switch 21 is connected in parallel with a unidirectionally conducting step-down branch 40, and the conduction direction of the step-down branch 40 is opposite to the charging direction.

[0024] The vehicle system includes a vehicle ECU, a starter and an engine, a generator, and a vehicle starting system. The vehicle ECU controls the starter and the engine, and the engine operates. The starting battery supplies power to the starter and the engine to start the starter and the engine. After the starter and the engine work normally, the generator is driven to generate electricity, and the generator generates electricity to charge the starting battery 30.

[0025] refer to Figure 1 The battery management module 10 is connected to the starting battery 30 to detect the single cell voltage of each single cell in the starting battery 30, the total voltage of the starting battery 30 (the voltage between B+ and B-), and the detection temperature of the starting battery 30 in real time. The battery management module 10 is also connected to both ends of the current detection circuit 23 to obtain the charging current value and the discharging current value of the starting battery 30. The battery management module 10 is also connected to the discharge switch 22 and the charging switch 21 to control the on and off of the discharge switch 22 and the charging switch 21. The battery management module 10 is also connected to the output voltage of the starting battery 30 (the voltage between P+ and P-) to obtain the voltage value output to the vehicle system. In this embodiment, a unidirectionally conducting step-down branch 40 is connected in parallel to the charging switch 21 of the starting battery 30.

[0026] The charging switch 21 is a MOS tube or a relay switch, and the starting battery 30 is a lithium battery.

[0027] The step-down branch 40 is formed by connecting one or more unidirectional conductive devices in parallel, and the unidirectional conductive device is a diode. Of course, the step-down branch 40 is not limited thereto, and can also be formed by connecting a diode (the diode can be a single diode or multiple diodes in parallel) and a step-down resistor in series. Of course, a MOS tube can also be used instead of a diode as a unidirectional conductive device.

[0028] refer to Figure 2 The present invention provides a startup battery detection control method 100, comprising steps S11 to S14.

[0029] S11, when the vehicle is about to start, the charging switch 21 of the starting battery 30 is controlled to be turned on.

[0030] S12, detecting the total voltage U0 of the starting battery 30, and comparing the total voltage U0 of the starting battery 30 with a starting limit threshold when the vehicle is started.

[0031] S13, when the total voltage U0 of the starting battery 30 exceeds the starting limit threshold, the charging switch 21 is controlled to be disconnected, so that the step-down branch 40 again lowers the output voltage of the starting battery 30 based on the total voltage U0. Generally, the output voltage of the starting battery 30 can be kept below the starting limit threshold, and step S14 is executed. When the total voltage U0 of the starting battery 30 does not exceed the starting limit threshold, step S14 is directly executed.

[0032] It is determined whether the total voltage U0 of the starting battery 30 is less than or equal to the starting limit threshold. If so, the charging switch 21 is controlled to be turned off and then step S14 is executed. If not, step S14 is directly executed.

[0033] S14, continue the process of starting the vehicle. The process of continuing the process of starting the vehicle can be seen Figure 4 Steps S2 and S3.

[0034] When the starting battery 30 is in a non-discharging state, the battery management module 10 also disconnects the charging switch 21 when any of the single cell voltages is greater than or equal to the overcharge protection threshold, and disconnects the charging switch 21 when the total voltage U0 of the starting battery 30 is greater than or equal to the full charge protection threshold. The full charge protection threshold is less than or equal to the start limit threshold.

[0035] refer to Figure 2 The battery management module 10 compares the discharge current value of the starting battery 30 with the discharge detection threshold to determine whether the starting battery 30 is in a discharge state, and disconnects the charging switch 21 when the starting battery 30 is not in a discharge state and any of the single cell voltages is greater than or equal to the overcharge protection threshold and the total voltage U0 of the starting battery 30 is greater than or equal to the full charge protection threshold. It is determined whether the discharge current value is less than the discharge detection threshold. If so, it is determined that the starting battery 30 is in a non-discharge state, otherwise, it is determined that the starting battery 30 is in a discharge state.

[0036] The above operation can be performed before starting, that is, before the vehicle starts, it also includes step S10, disconnecting the charging switch 21 when the discharge current value is less than the discharge detection threshold and any of the single cell voltages is greater than or equal to the overcharge protection threshold or the total voltage U0 of the starting battery 30 is greater than or equal to the full charge protection threshold.

[0037] Among them, the battery management module 10 also detects the single cell voltage of each battery cell in the starting battery 30, the total voltage U0 of the starting battery 30, and the discharge current value of the starting battery 30 in real time, compares the discharge current value with the discharge detection threshold, the single cell voltage and the overcharge recovery threshold, the total voltage U0 and the charging recovery threshold, and immediately turns on the charging switch 21 when the discharge current value is greater than or equal to the discharge detection threshold and the single cell voltage is less than or equal to the overcharge recovery threshold and the total voltage U0 is less than or equal to the charging recovery threshold, the overcharge recovery threshold is less than the overcharge protection threshold, and the charging recovery threshold is less than the full charge protection threshold.

[0038] Specifically, the overcharge protection threshold is 3.6V, the overcharge recovery threshold is 3.4V, the full charge protection threshold is 28V, and the charge recovery threshold is 27.8V. Among them, each threshold parameter is stored in the memory. In addition, the above thresholds are not limited to the above specific values, and specific values ​​can be set according to actual needs.

[0039] Among them, the battery management module 10 also executes step S15 after the vehicle enters the starting process, detects the charging and discharging status of the starting battery 30, and when the starting battery 30 is in the discharging state, turns on the charging switch 21 after a first delay. The first time length can be 1s, 2s or other time lengths. The battery management module 10 determines that the starting battery is in the discharging state when the discharge current value is greater than or equal to the discharge detection threshold. The discharge detection threshold is greater than or equal to 1A and less than or equal to 10A. In this embodiment, the discharge detection threshold is 5A. Step S15 is generally performed after step S3.

[0040] The better, reference Figure 3 Before starting the vehicle in step 14, step S14a is also included to determine whether the starting battery exceeds other safety protection conditions. If not, the vehicle starts, and if so, step S16 is executed to output a fault and prohibit ignition and start the engine. Among them, step S14a can be located before step S12, or after step S12, or performed simultaneously with step S12. Of course, step S16 also includes corresponding safety protection measures, such as turning off related switches, turning on cooling equipment, etc. Among them, step S14a is the safety protection of the starting battery such as overcurrent protection and overtemperature protection. This part is common knowledge in the field and will not be described in detail here.

[0041] The present invention also discloses a starting battery detection control device, including a processor, a memory, one or more programs and a unidirectional buck branch 40, wherein the charging switch 21 of the starting battery 30 is connected in parallel with the unidirectional buck branch 40, and the conduction direction of the buck branch 40 is opposite to the charging direction; the one or more programs are stored in the memory and are configured to be executed by one or more processors, and the programs include instructions for executing the starting battery detection control method 100 as described above. The processor is a processor of the battery management module 10, and the memory is a memory of the battery management module 10.

[0042] refer to Figure 4 The present invention also discloses a vehicle starting method, including steps S1 to S4.

[0043] Step S1, using a vehicle key to activate the vehicle ECU unit. Then, the starter battery detection control method 100 is executed.

[0044] Next, the operation before the vehicle starts in the starting battery detection control method 100 is performed: the charging switch 21 of the starting battery 30 is controlled to be turned on, and the total voltage U0 of the lithium battery is compared with the starting limit threshold when the vehicle starts. When the total voltage U0 of the starting battery 30 exceeds the starting limit threshold, the charging switch 21 is controlled to be turned off, so that the step-down branch 40 again lowers the output voltage of the starting battery 30 based on the total voltage U0, and then step S2 is performed. If the total voltage U0 of the starting battery 30 does not exceed the starting limit threshold, step S2 is directly performed.

[0045] S2, detecting the output voltage of the starting battery 30, and determining whether the output voltage of the starting battery 30 is less than or equal to the starting limit threshold. In this solution, the starting limit threshold is the overvoltage protection threshold of the vehicle ECU.

[0046] S3, if yes, then allow ignition to start the engine.

[0047] S4, if otherwise, output fault information and prohibit ignition and starting the engine.

[0048] Specifically, the following example illustrates a specific method for starting a vehicle according to the present invention:

[0049] When the vehicle is not in the starting state, the discharge current value, single cell voltage and total voltage of the starting battery 30 are detected in real time, and the charging switch 21 is turned off when the discharge current value is less than the discharge detection threshold, and any single cell voltage is greater than or equal to the overcharge protection threshold or the total voltage U0 of the starting battery 30 is greater than or equal to the full charge protection threshold. The charging switch 21 is immediately turned on when the discharge current value is greater than or equal to the discharge detection threshold, the single cell voltage is less than or equal to the overcharge recovery threshold, and the total voltage U0 is less than or equal to the charge recovery threshold.

[0050] S1, the user uses the car key to activate the vehicle ECU. At this time, the vehicle enters the state of starting. S11, the charging switch 21 of the starting battery 30 is controlled to be turned on, and then step S12 is executed to determine whether the total voltage U0 of the lithium battery is less than or equal to the starting limit threshold when the vehicle is started. If so, step S14a is executed to perform other safety tests. If not, step S13 is executed to control the charging switch 21 to be disconnected so that the step-down branch 40 can lower the output voltage of the starting battery 30 again based on the total voltage U0, and then step S14a is executed to perform other safety tests. In step S14a, it is determined whether the starting battery exceeds other safety protection conditions. If not, step S14 is executed to allow the engine to be ignited and started. If so, corresponding safety protection measures are executed, faults are output, and the vehicle is prohibited from igniting and starting the engine.

[0051] Subsequently, after the user starts the engine, the engine starts to start and drives the generator to generate electricity, thereby charging the starting battery 30, and continues to monitor the discharge current value, single cell voltage and total voltage of the starting battery 30, and disconnects the charging switch 21 when the discharge current value is less than the discharge detection threshold and any of the single cell voltages is greater than or equal to the overcharge protection threshold or the total voltage U0 of the starting battery 30 is greater than or equal to the full charge protection threshold.

[0052] After the vehicle key is pulled out or the vehicle is turned off, the ECU controls the engine and the generator to stop working, and stops charging the starting battery 30. If the starting battery 30 discharges to external loads such as inverters and lights, the charging switch 21 is turned on for a first time delay when the discharge current value is greater than or equal to the discharge detection threshold, and the charging switch 21 is turned on immediately when the discharge current value is greater than or equal to the discharge detection threshold, the single cell voltage is less than or equal to the overcharge recovery threshold, and the total voltage U0 is less than or equal to the charging recovery threshold.

[0053] That is to say, in the non-starting process, the present invention can use the voltage monitoring of both the single cell voltage and the total voltage to perform overvoltage protection on the starting battery 30, ensuring that the total voltage of the starting battery 30 will not exceed the starting limit threshold in most cases, and even if the total voltage exceeds the starting limit threshold in special cases, it will not exceed too much, and the step-down branch can reduce the output voltage of the starting battery 30 to a range less than or equal to the starting limit threshold by turning off the charging switch 21. After the ignition is allowed to start the engine, if the vehicle supplies power to the on-board equipment to discharge the starting battery 30, the charging switch 21 can be turned on in time to prevent the unidirectional conducting device of the step-down branch from overheating and damage.

[0054] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
