Di Holo Battery, kami telah membuat kerajinan paket baterai khusus selama lebih dari 18 tahun. Kami memahami bahwa mengembangkan solusi ketenagalistrikan baru menimbulkan pertanyaan penting mengenai kinerja dan keselamatan. Itu sebabnya kami membuat FAQ ini untuk menjawab pertanyaan umum dari para insinyur dan manajer proyek, membantu Anda dalam perjalanan paket baterai khusus Anda.
Desain Inti dan Pemilihan Komponen
Pertanyaan: Bagaimana Anda mengetahui jenis sel yang harus dipilih untuk proyek Anda?
Pemilihan sel adalah dasar kinerja baterai Anda. Pilihannya bergantung pada keseimbangan yang cermat antara persyaratan utama aplikasi Anda:
- Energy Density (Wh/kg) vs. Power Density (W/kg): Does your device need long runtimes (e. g., UAVs, medical devices) or high bursts of power (e. g., power tools, robotics)? Lithium Nickel Manganese Cobalt (NMC) cells provide higher kepadatan energi, while Lithium Iron Phosphate (LiFePO4) excels in siklus hidup.
- Cycle Life: How many charge/discharge cycles are required? LiFePO4 provides the longest cycle life, ideal for solar storage and industrial use.
- Operating Environment: Will the battery encounter extreme temperatures? Some chemistries, like sodium-ion batteries, are better for cold conditions.
- Safety Profile: Consider safety risks; LiFePO4 is known for its thermal stability.
Tentukan kapasitas dan voltase yang dibutuhkan perangkat Anda, termasuk penarikan arus. Sel yang berbeda memiliki kapasitas dan laju pelepasan yang berbeda-beda, jadi pertimbangkan faktor bentuk sel untuk memenuhi batasan dimensi. Insinyur Baterai Holo menganalisis faktor-faktor ini untuk merekomendasikan sel Kelas A dari pemasok terkemuka yang selaras dengan sasaran biaya dan kinerja proyek Anda.
Pertanyaan: Bagaimana Anda menentukan jenis bahan apa yang dibutuhkan untuk sebuah selungkup?
Saat memilih bahan penutup yang tepat, kami mempertimbangkan faktor-faktor seperti kebutuhan Peringkat IP, kapasitas berat, manajemen panas, dan kepatuhan terhadap peraturan (seperti sifat mudah terbakar UL94).
Jika Anda membutuhkan pilihan yang ringan dan terjangkau dengan ketahanan benturan yang baik dan bentuk khusus, plastik seperti ABS dan PC adalah pilihan yang sangat baik.
Namun, untuk perlindungan EMI berkekuatan tinggi, efektif, dan manajemen panas di lingkungan yang menuntut seperti lingkungan industri atau militer, logam seperti aluminium dan baja adalah pilihan yang ideal.
Kami siap membantu Anda memilih bahan terbaik untuk memastikan sel Anda aman, mengelola panas secara efektif, dan berintegrasi secara sempurna dengan desain produk Anda.
Pertanyaan: Bagaimana Anda berencana mengendalikan termal di dalam wadah baterai?
Efektif manajemen termal is non-negotiable for safety and longevity. Poor heat management results in worse performance, faster wear and tear, and potential safety issues. Here’s how we’re addressing it:
- Passive Cooling: We use thermally conductive materials like aluminum cases and thermal interface pads that naturally dissipate heat, ideal for moderate power demands.
- Active Cooling: For high-power situations, such as EV powertrains or advanced energy storage, we employ fans or liquid cooling to manage excess heat.
- BMS Integration: Our custom Battery Management Systems monitor cell temperatures in real-time. If overheating occurs, they can reduce charge/discharge rates or shut down systems to ensure safety.
The Role of the Battery Management System (BMS)
Question: Do all battery packs need a BMS to control the charge and discharging?
Not all battery packs need a BMS, but lithium-ion packs do. A BMS is essential for:
- Safety: It protects against overcharge, over-discharge, over-current, and short circuits.
- Pertunjukan & Longevity: It balances cells to ensure even wear and maximize cycle life.
- Monitoring: It provides data on the State of Charge (SoC), State of Health (SoH), and other parameters through protocols like CANBus or Bluetooth.
Question: How do you determine when the battery should be charged if it’s not being used or has been in long-term storage?
Lithium-ion batteries have a low self-discharge rate, but a specific protocol is needed for long-term storage.
We recommends storing batteries at 30-50% SoC in a cool, dry place. For inventory or seasonal use, the smart BMS enters a low-power “sleep” mode but periodically checks voltage. If the voltage drops below a safe threshold, it alerts the user for maintenance charging.
Question: Can resettable fuses be used in packs?
Resettable fuses, or PPTCs, aren’t good for the main protection in high-performance battery packs. They have higher resistance and can trip due to temperature changes, not just over-current.
Therefore, we prefer using dedicated solid-state switches in the BMS, along with regular fuses for those rare major failures. This approach allows us to build a solid, multi-layered safety setup.
Certification, Shielding, and Cost
Question: Is EMI/RFI shielding needed for battery packs?
For basic packs with just cells and basic protection, you usually don’t need to worry about EMI/RFI shielding.
However, for smart packs with features like BMS, communication systems, DC-DC converters, or high switching currents, shielding might be necessary.
It really depends on regulations and the sensitivity of the device you’re working with.
Question: Can Holo Battery help to certify battery packs for customers?
Absolutely. As an ISO-certified manufacturer, we have extensive experience helping clients navigate the certification process. We can manage and secure all the major international certifications for your battery pack, including but not limited to:
- UL 2054 / UL 2580 (North America)
- IEC 62133 (International)
- CE (Europe)
- UN38.3 (Transportation)
By using pre-certified cells and komponen, we ensure your product reaches the market quickly and compliantly!
Question: What are the development costs, including certifications for the battery?
Costs can vary significantly based on the project’s complexity, the amount of work required, and necessary certifications. The main factors affecting costs include:
- Custom Engineering: The complexity of the BMS, mechanical design, and thermal management.
- Prototyping: The number of prototype units needed for testing.
- Certification: The specific standards and regions you’re targeting.
- Tooling: Costs for custom molds or fixtures for large-scale production.
