Description

A method and system for improving battery life

Technical field

The present invention relates to the field of vehicle control technology, and in particular, to a method and system for improving battery life.

Background technique

In order to improve the driving experience of the majority of drivers, the truck was designed to provide an on-board high-power inverter for cooking and boiling water when parked, and a parking air conditioner for resting when parked. Therefore, larger-capacity lead-acid batteries came into being. . However, excessive use and failure to recharge in time have become the main factors affecting the life of these large-capacity lead-acid batteries. How to improve the working environment of lead-acid batteries and prevent high claims is the current research direction of major truck factories.

Currently, in the field of trucks, the main methods to extend battery life are low-voltage battery audible and visual warnings and low-voltage power outages. By monitoring the battery voltage, when the battery voltage reaches a certain level, the truck instrument image color and buzzer are used. The controller will warn the driver and inform the driver that the battery voltage is too low at this time and pay attention to replenishing the battery. When the battery voltage continues to be low for a period of time, the controller will cut off the power supply circuit by controlling the main power switch to avoid further battery loss. However, it will give a warning when the battery voltage is low. Merely informing the driver of the current situation, but not taking any further action, has limited improvement in battery life, and deviates from the customer's willingness to continue using electricity. It only considers preventing further battery loss, but does not take into account that failure to replenish power in time will cause irreversible vulcanization damage to the battery. .

Therefore, how to avoid battery loss and thereby extend battery life is an urgent technical problem that needs to be solved.

Detailed ways

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the appended claims.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

Referring to Figure 1, Figure 1 shows a flow chart of a method for improving battery life provided by the present invention. As shown in Figure 1, the method includes the steps:

Step S101: Determine whether the vehicle voltage is overloaded when the generator is working.

Specifically, the power distribution controller IDB determines in real time whether the vehicle voltage when the generator is working is greater than the set threshold; when the vehicle voltage is less than the set threshold, it is determined that the vehicle voltage is in an overload state; when the vehicle voltage is greater than When setting the threshold, it is judged that the vehicle voltage is in a low load state.

It is easy to understand and give an example. You can judge whether it is overloaded by the vehicle voltage when the generator is working (taking 28V as the boundary, it is 28±0.2V when balanced, when the load is small, it is higher than 28.2V, when the load is large, it is lower than 27.8V).

When the vehicle voltage is 27.1V, the power distribution controller IDB determines that the generator is seriously overloaded at this time. IDB sends a request to the engine ECM to increase the engine speed. At this time, the vehicle voltage rises to 27.5V, and IDB determines that the load of the generator is still relatively high. At this time, the IDB uses the door opening signal and the inverter output to determine the driver's intention (whether to get out of the car and use electricity).

Step S102: When it is determined that the vehicle voltage is overloaded, adjust the engine speed to increase the power generation of the generator, and continue to determine whether the vehicle voltage is overloaded when the generator is working.

Specifically, when it is determined that the vehicle voltage is overloaded, the IDB is used to send a speed increase request to the engine ECM, and the engine is used to increase the generator speed; when the generator speed is increased, the IDB is used to continuously monitor the vehicle voltage, and when the engine ECM When the vehicle voltage is still less than the set threshold, it is determined that the vehicle's power consumption is still in an overload state.

For easy understanding, let’s take an example. When the vehicle voltage is 27.1V, the power distribution controller IDB determines that the generator is seriously overloaded. IDB sends a request to the engine ECM to increase the engine speed. At this time, the vehicle voltage rises to 27.5V, and IDB determines that the generator is generating electricity. The load of the machine is still relatively large. At this time, the IDB uses the door opening signal and the inverter output to judge the driver's intention.

In one embodiment, the operating status of the vehicle is determined based on the vehicle speed signal and the braking signal;

When it is detected that the vehicle speed signal is 0 and there is a braking signal, it is determined that the vehicle is in an idling state; when it is determined that the vehicle is in a non-idling state, it is prohibited to adjust the engine speed.

It is understandable that the engine speed can be adjusted to increase the generator speed, thereby increasing the generator's generating power. However, automatically increasing the engine speed during driving will deviate from the driver's original intention of controlling the vehicle and cause danger, so the vehicle speed signal is used If it is 0 and the parking brake signal exists at the same time, it can be confirmed that the vehicle is starting in place, and the increase in engine speed will not cause danger.

Step S103: When it is determined that the vehicle voltage is still overloaded, it is determined based on the door opening signal, the vehicle output power and the vehicle interior temperature whether the driver or passengers get out of the vehicle to use electricity.

Specifically, the vehicle door opening signal is monitored based on the door touch sensor; the vehicle output power is monitored based on the inverter; the interior temperature is monitored based on the air conditioning controller;

When it is determined that the vehicle door is open, the vehicle is monitored for high power output, and the temperature inside the vehicle is similar to the temperature outside the vehicle, it is determined that the driver and passengers get off the vehicle and use electricity.

To facilitate understanding, for example, any door is opened (the door opening and closing status is monitored through the door touch sensor) and continues for more than 30 seconds, and the indoor temperature (monitored through the indoor temperature sensor and outdoor temperature sensor) is monitored by the air-conditioning controller (monitored by the indoor temperature sensor and outdoor temperature sensor). The outdoor temperature is approximately equal), indicating that the driver and passengers do not pay attention to the closed environment control (cooling or heating function) of the cab at this time; in addition, the inverter monitors (monitors the output through the power chip) to have high power output, combined with the door opening status , it was determined that the driver and passengers had used electricity to cook and stir-fry under the car.

Step S104: If so, turn off other electrical equipment in the vehicle until the voltage of the entire vehicle is maintained within a safe range to extend the life of the battery.

Specifically, when it is determined that the driver and passengers get out of the car to use electricity, turn off the in-car entertainment system, lighting system, refrigerator, wiper and air conditioner, and keep the engine and generator running normally to allow the vehicle voltage to rise back to a safe range.

To facilitate understanding, for example, any door is opened (the door opening and closing status is monitored through the door touch sensor) and continues for more than 30 seconds, and the indoor temperature (monitored through the indoor temperature sensor and outdoor temperature sensor) is monitored by the air-conditioning controller (monitored by the indoor temperature sensor and outdoor temperature sensor). The outdoor temperature is approximately equal), indicating that the driver and passengers do not pay attention to the closed environment control (cooling or heating function) of the cab at this time; in addition, the inverter monitors (monitors the output through the power chip) to have high power output, combined with the door opening status , it is determined that the drivers and passengers have used electricity for cooking and cooking under the car (worrying about polluting the environment inside the cab); the power distribution controller IDB communicates with the air conditioning control panel to turn off the air volume and communicate through the door opening signal and the high power output of the inverter. The large screen turns off the audio-visual entertainment system, indoor lights, low beam lights, high beam lights, refrigerators, wiper systems, etc., only keeping the engine and generator running normally, saving electricity to reduce the power supply load of the generator, and ultimately realizing the overall The vehicle voltage is maintained at 28±0.2V, and the battery can be effectively charged; as the battery power recovers, the load of the generator gradually decreases, and the vehicle voltage continues to rise above 28.2V. The IDB gradually restores the power supply and related systems according to the functional priority. power consumption to maximize energy utilization.

Optional, any door is open (the door opening and closing status is monitored through the door touch sensor) and lasts for more than 30 seconds, and the indoor temperature monitored by the air conditioning controller (monitored through the indoor temperature sensor and outdoor temperature sensor) does not change much (indoor and outdoor temperature sensors). There is still a difference of about 5℃ in the outdoor temperature), indicating that the driver and passengers still need to control the closed environment of the cab (cooling or heating function) at this time; in addition, the inverter monitors (monitoring output through the power chip) to have high power output. Combined with the door opening situation, it is determined that the drivers and passengers have used electricity to cook and stir-fry under the car (worrying about polluting the environment in the cab) but there are still people in the cab, and the basic needs of cooling or heating need to be ensured; the power distribution controller IDB passed The door opening signal and the high power output of the inverter communicate with the air conditioning control panel to reduce the air volume and maintain the indoor temperature at 28°C (the acceptable temperature for the human body for cooling in summer)/16°C (the acceptable temperature for the human body for heating in winter). The large communication screen is closed. The audio-visual entertainment system, indoor lights, low beams, high beams, refrigerators, wiper systems, etc. are turned off to keep the engine and generator running normally, save electricity, and reduce the power supply load of the generator, ultimately maintaining the vehicle voltage at 28 ±0.2V, the battery can be charged effectively.

In one embodiment, as the battery power recovers, the load of the generator gradually decreases, the vehicle voltage continues to rise to above 28.2V, and the IDB gradually restores the power supply to the relevant systems according to the functional priority (temperature sensing>light sensing>entertainment sensing) and power consumption to maximize energy utilization.

It should be noted that the truck battery is generally used to start the vehicle and provide power when the vehicle is stopped. After use and discharge, it needs to be recharged in time while the engine is running to prevent the battery from failing to recharge effectively and causing the plates to become vulcanized and eventually decay and lose power. power supply capability. To this end, regulation is required to ensure that the generator's power generation can meet the vehicle's power supply needs.

It is understandable that the power supply of commercial vehicle generators is limited. When multiple high-power electrical appliances are used at the same time, it will cause the battery to lose power and reduce its service life. Through the method of this application, the damage speed of the battery can be delayed and the service life of the battery can be increased. , and it can also ensure that the battery is effectively charged, so that the vehicle can start normally, while avoiding battery loss and further damage to the battery.

It can be understood that this application combines the vehicle voltage to determine whether the vehicle voltage is overloaded when the generator is working and whether the generated power meets the vehicle power consumption and battery replenishment requirements; when it is determined that the vehicle voltage is overloaded and the vehicle voltage is too low, When the generated power is insufficient, adjust the engine speed to increase the generator's generated power, and continue to determine whether the vehicle voltage when the generator is working is overloaded and whether the output generated power is sufficient; when it is determined that the vehicle voltage is still overloaded and too low, Based on the door opening signal, the vehicle output power and the temperature inside the vehicle, it is determined whether the driver and passengers get out of the car to use electricity; if so, other electrical equipment in the vehicle will be turned off until the voltage of the vehicle is maintained within a safe range to extend the life of the battery.
