Description

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels, adopt new vehicle power devices), and combine advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles and new technologies and structures. New energy vehicles are different from fuel vehicles and mainly rely on on-board power batteries to provide energy. Electric vehicles consume electric energy during driving, and the battery energy needs to be replenished when the electric energy is consumed. The energy replenishment form is to convert the energy of the power grid or other energy storage devices into the energy of the battery, and this process is called charging. The state regards the development of new energy as an important measure to improve the environment and save costs, and with the continuous development of new energy technology, the market share of electric vehicles is growing, and electric vehicles have replaced fuel vehicles in an unstoppable manner.

[0003] With the continuous growth of the number of electric vehicles, the charging problem has become an important factor restricting the popularization of electric vehicles. When charging an electric vehicle, many owners plug in the charging gun after parking and start charging at the same time. Taking 18:00 as an example, which is usually the time when people go home, at this time, it is the peak of electricity consumption, and if charging is performed during the peak period of electricity consumption, the voltage of the power grid will also decrease, thereby affecting the charging power. Environmental factors such as temperature and humidity can affect the conversion efficiency of the charging pile. After a long time of driving in the outdoor environment, the vehicle will be in a low-temperature, high-temperature, or high-humidity environment, and the charging acceptance ability of the battery will decrease, and if charging is performed immediately, the charging efficiency will also be affected.

[0004] The charging efficiency of new energy vehicles is affected by many factors. If the charging gun is plugged in immediately, the charging efficiency will often be affected due to the inappropriate timing. SUMMARY

[0022] The present application will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0023] The following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical terms used in the present application have the same meanings as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present application are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0024] In order to solve the problem of low charging efficiency of new energy vehicles due to improper charging time, the present application provides a new energy vehicle charging system, as shown in Figure 1 The charging module is electrically connected with the control module. The control module is configured to obtain charging mode information of a user, and send a charging instruction to the charging module; and the charging module is configured to respond to the charging instruction and start charging.

[0025] The user controls the charging module to charge through the control module. The user can charge immediately after plugging in the charging gun, or start charging at any time period set in advance, so as to charge the new energy vehicle at the appropriate time and achieve the best charging effect and improve the charging efficiency.

[0026] In some embodiments, the control module includes a central control host unit, which is configured to obtain immediate charging information of a user, and send an immediate charging instruction to the charging module.

[0027] In some embodiments, the charging module includes a charging gun unit and a charging machine unit, and the charging module is configured to obtain charging preparation state information after the charging gun unit is connected with the charging machine unit. When the charging preparation state information is standard charging preparation state information, the charging is started in response to the immediate charging instruction. The standard charging preparation state information includes normal CC connection, normal CP connection, normal charging seat temperature, and normal charging gun electronic lock state.

[0028] CC is a charging connection confirmation signal, and the on-board charger judges whether the charging gun and the charging port are completely connected by detecting the resistance value between CC and PE. The CC signal connection refers to the charging connection confirmation signal in the electric vehicle charging system. When the CC signal connection is normal, the whole vehicle can normally charge. During the charging process of the electric vehicle, the CC signal is used to confirm the connection state of the charging plug and the vehicle, and to inform the vehicle charging system to start charging. When the CC signal connection is normal, the vehicle charging system will detect that the charging plug has been correctly connected and start charging.

[0029] CP is a charge control confirmation signal, and the on-board charger judges whether the charging connection device is completely connected by detecting the CP signal, and can confirm the maximum power supply current of the current power supply device.

[0030] The charging gun plug can generally withstand temperatures between -20°C and 50°C. After the vehicle is exposed to high temperatures for a long time or travels a long distance, the temperature of the power supply box rises, causing the temperature of the battery to rise. In this case, if charging is immediately performed, it can accelerate the aging and damage of the in-vehicle circuit, can cause a fire, and can also affect the charging efficiency of the battery.

[0031] In some embodiments, as shown in FIG. 1, the control module further includes a remote monitoring unit. The central control host unit is further configured to: obtain timing charging information of a user, send a first timing charging instruction to the charging module, the timing charging information including a start charging countdown time length; send a timing instruction and the start charging countdown time length to the remote control unit.

[0032] The remote monitoring unit is configured to: in response to the timing instruction, start timing and record the timing time length, and when the timing time length is equal to the start charging countdown time length, send a second timing charging instruction to the charging module.

[0033] The central control host unit has a charging mode selection switch interface, which is divided into "immediate charging / timing charging" modes. In the timing charging mode, the charging start time can be adjusted, such as starting after 1 hour or starting after 2.5 hours, with 0.5 hours as a time period. The countdown time signal is sent by the central control host to the CAN network, and the remote control unit receives the timing charging mode.

[0034] In some embodiments, the charging module is configured to: after the charging gun unit is connected to the charging machine unit, obtain charging preparation state information; and when the charging preparation state information is standard preparation state information, start charging in response to the first timing charging instruction and the second timing charging instruction.

[0035] When the user selects the "timing charging mode" on the central control host, the charging module will receive the first timing charging instruction. At the same time, the remote monitoring unit will also start timing from zero. For example, set to start charging after 1 hour, when the remote monitoring unit timing time length reaches 1 hour, it will send a second timing charging instruction to the charging module. At this time, the charging module has received the first timing charging instruction and the second timing charging instruction, and if the CC connection is normal, the CP connection is normal, the charging seat temperature is normal, and the charging gun electronic lock state is normal, the charging will be started.

[0036] ​In some embodiments, the charging unit further comprises a battery management system unit, and the control module further comprises a mobile phone vehicle application unit.

[0037] The BMS battery management system unit comprises a BMS battery management system, a control module, a display module, a wireless communication module, an electrical device, a battery pack for powering the electrical device, and an acquisition module for acquiring battery pack battery information.

[0038] The BMS battery management system realizes the following functions: measurement of battery terminal voltage; energy balancing between single batteries, i.e. equalizing charging of single batteries to make each battery in the battery pack reach a balanced and consistent state; measurement of total battery pack voltage; measurement of total battery pack current; SOC calculation: accurate estimation of the state of charge (SOC) of the power battery pack, i.e. the remaining battery capacity, to ensure that the SOC is maintained within a reasonable range and prevent damage to the battery due to overcharging or overdischarging; dynamic monitoring of the working state of the power battery pack: during the battery charging and discharging process, the terminal voltage and temperature of each battery in the battery pack, the charging and discharging current, and the total voltage of the battery pack are collected in real time to prevent overcharging or overdischarging of the battery; real-time data display; data recording and analysis: selection of problematic batteries to maintain the reliability and efficiency of the entire battery pack; communication networking function.

[0039] In some embodiments, the mobile phone vehicle application unit is further configured to send a timing charging start instruction to the remote control unit. The remote monitoring unit is further configured to send a third timing charging instruction to the charging module in response to the timing charging start instruction. The charging module is configured to start charging in response to the first timing charging instruction and the third timing charging instruction when the charging preparation state information is standard preparation state information.

[0040] When the user has selected the "timing charging mode" on the central control host unit, the user can directly start charging through the mobile phone vehicle application installed on the mobile phone even if the set charging time has not arrived. At this time, the charging module will receive a third timing charging instruction, and if the CC connection is normal, the CP connection is normal, the charging seat temperature is normal, and the charging gun electronic lock locking state is normal, the charging will be started.

If the CC connection is normal, the CP connection is normal, the charging seat temperature is normal, and the charging gun electronic lock locking state is normal at this time, the charging module will start charging immediately in response to the immediate charging instruction. The user can check the real-time battery information at any time on the mobile phone vehicle application.

[0044] When the charging gun is inserted into the charging port, the user selects the "timing charging" mode on the central control host and sets the charging to start after two hours. At this time, the central control host unit sends a first timing charging instruction to the charging module and sends a timing instruction and a start charging countdown time length to the remote monitoring unit, wherein the start charging countdown time length is two hours. At this time, the remote monitoring unit starts timing. When the timing time length reaches two hours, the second timing charging instruction is sent to the charging module.
