It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The following description, in conjunction with the accompanying drawings... Figure 1-9 Further explanation is provided regarding modular rechargeable batteries and battery cells for electric vehicles.

[0038] Example 1

[0039] A modular rechargeable battery for electric vehicles, comprising:

[0040] The battery body 1 has a foldable lifting structure 2;

[0041] Positioning hole structure 3 is provided above the battery body 1;

[0042] Positioning structure 4 is located below the battery body 1;

[0043] The battery body 1 is also equipped with a power interface 5 and a chip and / or RFID tag and chip interface 6 with unique identification and charge / discharge count recording functions.

[0044] Furthermore, the number of positioning hole structures 3 and positioning structures 4 is two (*the number can be increased according to actual needs). The positioning structure 4 is used to position the lower part of the rechargeable battery 14 to the battery box 8.

[0045] Furthermore, the power interface 5 and the chip and chip interface 6 are located below the battery body 1 (*the position can be adjusted according to actual needs).

[0046] The battery body 1 can be customized in specific shape and size according to actual needs; the lifting structure 2 facilitates the lifting and transportation of the battery, and this structure can be folded and stored in the battery groove; the positioning hole structure 3 cooperates with the top cover of the box to ensure accurate battery positioning and prevent movement; the positioning structure 4 cooperates with the lower groove of the box to ensure accurate battery positioning and prevent movement; the power interface 5 is used for charging and discharging the power supply; the chip interface 6 is an interface module for identifying chips, which cooperates with the chip reading and writing devices of the matching charging and swapping devices / electric vehicles, etc., to realize information interaction.

[0047] 1. The modular intelligent charging battery for this electric vehicle (hereinafter referred to as "this battery") adopts a standardized design to ensure universal compatibility across the entire network:

[0048] ① The external dimensions, design (positioning, clamping, etc.) and charging / discharging interfaces of the battery are standardized to ensure compatibility with the battery box of intelligent electric vehicles and the charging box of intelligent charging equipment;

[0049] ② The design standards, specifications, locations, technical parameters, and hardware and software interface protocols of the battery identification chip and RFID tag (or IoT tags that can provide similar functions, hereinafter referred to as "RFID-like tags") are standardized to ensure smooth communication with the management system.

[0050] 2. This battery adopts a modular design, and one or more battery packs can be combined by connecting these batteries in series or parallel.

[0051] ① A battery pack (the specific number of battery cells can be matched according to the voltage and current indicators required by a battery pack and the design load voltage and current parameters of a single battery) can effectively meet the basic driving and driving needs of an electric vehicle, and each additional battery pack can increase the corresponding driving range.

[0052] ② Modular design can also effectively reduce the weight of each battery, making it easier for batteries to be produced, transported, tested and replaced, and more scalable and practical;

[0053] ③ Each battery pack can be charged and swapped individually. Once a battery pack is completely depleted, the entire battery module can be replaced, effectively protecting the battery and maximizing its theoretical lifespan. Alternatively, each battery can be charged individually as needed.

[0054] ④ The design of multiple battery packs allows for the separate charging of battery packs (or some module batteries within a pack) that need charging, while other battery packs can still effectively ensure the normal operation of the electric vehicle.

[0055] 3. Each battery has a unique identification chip (one item, one code) and an RFID-like tag;

[0056] ① The chip records the number of times the battery is charged and discharged (the number of charge and discharge cycles is linked to the battery life), and can interact in real time with smart electric vehicles, smart charging and discharging devices, management systems, etc. through the chip read and write interface, thereby effectively monitoring the circulation and usage of the battery, making its source traceable and its destination trackable.

[0057] Example 2

[0058] The present invention also includes a modular rechargeable battery unit for electric vehicles, comprising: a plurality of rechargeable batteries 14 as described in Embodiment 1, built into a battery box 8; a battery box cover 9 for sealing the battery box 8, with a cover handle 10 disposed on the top of the cover; a battery unit positioning structure 7 for connecting to the vehicle body, which is located on the battery box 8; the battery box cover 9 is provided with a plurality of cover positioning posts 11 for cooperating with the positioning hole structure 3; and a battery clamping link 15, which is connected to a battery clamping left link 21 and a battery clamping right link 22 for clamping the battery, respectively; the battery box 8 is provided with a charging interface 12 and an energy storage power interface 13 for reverse power supply.

[0059] Furthermore, it includes: a thermal insulation layer 16, the bottom, perimeter and top of which are respectively provided with thermal insulation medium 17.

[0060] Preferably, it further includes:

[0061] The insulation layer sensor 20 is located inside the insulation layer 16;

[0062] Sensor contact 19 is disposed on the rechargeable battery 14;

[0063] A rechargeable battery sensor 18 is disposed below the rechargeable battery 14.

[0064] Each rechargeable battery 14 has two battery positioning holes 3, which cooperate with the upper cover positioning post 11 of the battery box upper cover 9. When the battery box upper cover 9 is pulled up, the battery clamping link 15 drives the battery clamping left link 21 and the battery clamping right link 22 to move to the left and right respectively, away from the positioning structure at the bottom of the battery. When the upper cover assembly is lowered, the upper cover positioning post 11 on the battery box upper cover 9 enters the battery positioning hole 3, and the battery clamping link 15 drives the battery clamping left link 21 and the battery clamping right link 22 to move to the right and left respectively, clamping the positioning structure at the bottom of the battery, so that the position of the upper cover and the battery is stable.

[0065] The vehicle's battery system can be configured with either thermal insulation or ambient temperature settings. In the thermal insulation mode, when the battery temperature drops to a set temperature of -5°C, the temperature sensor (thermal insulation sensor 20) in insulation layer 5 transmits data to the vehicle management system. The vehicle management system can then automatically activate the heating mode, and the insulation medium 17 in insulation layer 16 begins heating. Heating stops when the battery temperature reaches the set temperature of 5°C. This prevents the battery from draining too quickly in cold winter conditions, ensuring the vehicle can be started at any time.

[0066] This invention also has the following features:

[0067] a) Each battery module has a unique code, essentially giving each battery an ID card. All battery module identification information is centrally and uniformly stored in the cloud server's database, ensuring that the identification information is unique across the entire network. The cloud server provides data query and submission interfaces, allowing for queries at any time.

[0068] b) Each battery is equipped with an identification chip and a dedicated, unique RFID tag (or an IoT tag that can provide similar functionality, hereinafter referred to as "RFID-like tag"). The identification information in the chip and the RFID-like tag is written and cannot be erased or rewritten, ensuring that the identity cannot be maliciously copied or tampered with.

[0069] c) Other battery attributes, power level, and number of charging cycles are also stored in the chip. The chip is readable and writable, and the information is encrypted to ensure that the information is not maliciously tampered with.

[0070] d) Information reading and writing devices for matching identification chips and RFID-like tags. These devices are configured in handheld PDAs, electric vehicles, and smart charging and swapping devices as needed. They can read and write information in the chips and RFID-like tags in real time and present it to the user through a display device. These devices have real-time Internet access (LAN, WIFI, 4G, or 5G can be used). They can interact with the cloud server through the data query and submission interface provided by the cloud server. The interactive data is encrypted to achieve secure and real-time two-way transmission of information.

[0071] e) Information aggregated in real time to the cloud server can be sorted and filtered, and then the effective information can be fed back to the user (for example, through a mobile APP).

[0072] ② When the battery level exceeds 50%, record 0.5 charging attempts. When the battery level is below 50%, record 1 charging attempt. The remaining battery level can also be displayed to the system in real time.

[0073] ③ Type RFID tags can be identified using composite identification tags (e.g., a combination of a high-performance anti-metal 3D RFID tag and a regular QR code), which facilitates equipment identification and inventory management by different scanning devices.

[0074] 4. Real-time information interaction enables quick payment and battery swapping at smart battery swapping stations. The cost of replacing a battery at a swapping station is as follows:

[0075] ① Pay the minimum necessary battery replacement service fee;

[0076] ② Pay the price difference between the new and old battery modules (i.e., the price difference between the battery life and remaining capacity of the battery module to be replaced and the price difference between the battery life of the fully charged battery module to be replaced).

[0077] 5. Through real-time interaction with the management system, the battery achieves full life-cycle monitoring, which can effectively assist battery recycling organizations in carrying out unified and fixed-point secondary recycling of waste batteries, reducing environmental pollution and promoting resource reuse.

[0078] This solution provides a standardized modular rechargeable battery that can be freely plugged in and out. When used in conjunction with a smart electric vehicle, a smart charging and swapping device for modular batteries in electric vehicles, and a modular battery management system for electric vehicles, it enables real-time monitoring of battery power and charge / discharge cycles, complete separation of battery charging and usage scenarios, rapid battery pack replacement and payment settlement, and effective tracking of the entire battery lifecycle. This provides a faster and cheaper user experience than refueling, and solves range anxiety!
