Electric vehicles are already at 800V—is there really a need to push them all the way to 1200V? Source: WeChat Official Account “Frey Liu” Is 1200V the Next Frontier or Just Marketing Overkill? The Core Debate: Why the 800V “Sweet Spot” is Enough The EV industry is currently locked in a high-voltage arms race. While we’ve shifted from 400V to 800V/900V, some are already pushing for 1200V platforms. My Take: The performance dividends from the 800V transition are far from exhausted. Rushing to 1200V before solving existing cost and infrastructure hurdles is more about “tech-flexing” than improving the user experience. It will inevitably drive up costs with diminishing returns. 1.

Hot Take: A Sharp Critique of Donut lab’s First Solid-State Battery Test Report Source: WeChat Official Account “FreiLiu” 弗雷刘 Not long ago, the Finnish solid-state battery company Donut Lab made waves with a major announcement. They unveiled a battery cell technology boasting some truly staggering specs: Energy Density: 400 Wh/kg Charging Speed: Full charge in just 5 minutes Discharge Profile: Encourages full charge/discharge cycles Design Life: 100,000 cycles Operating Temperature: -30°C to 100°C Furthermore, the production process avoids rare materials entirely, utilizing “ubiquitous” eco-friendly materials that are free from geopolitical constraints. Perhaps most impressively, the production cost is reportedly lower than that of lithium-ion batteries with the same specifications. Today,

How to map the Neware aux testing channels? This is the latest version of the Neware aux channel; other older versions are still mapped here. The mapping method and location remain largely unchanged. The below tutorial will guide you how to map Neware aux testing channles in software. Open the Set-Mapping window, you can find the blue battery symbol if you have aux channels. (The blue means the aux channel can be mapped. You can not do the aux channel mapping if the aux channels’ color shows grey. ) Click link for “Neware BTS4000 Set up” to learn about how to open the Set-Mapping window. Below is the Set-Mapping window

The First All-Solid-State Battery Test Report Released by Donut Lab The Following is the Response from Google Gemini Publication Date: February 2026 Testing Entity: VTT Technical Research Centre of Finland Cell Type: 26Ah Solid-State Pouch Cell 1. Test Objectives and Scope The independent validation conducted by VTT focused on the Extreme Fast Charging (XFC) capabilities and thermal stability of Donut Lab’s solid-state battery (SSB) prototypes. The test aimed to verify the high-rate performance claims made by the Finnish startup during CES 2026. 2. Extreme Fast Charging (XFC) Performance 11C Charge Rate: The cell demonstrated an extreme charging capability, reaching an 80% State of Charge (SoC) in just 4.5 minutes. A

Third-Party Test Report for QuantumScape Single-Layer Solid-State Battery (Released October 27, 2021) The Following is the Response from Google Gemini 1. Overview of the Testing Entity The independent testing was conducted by Mobile Power Solutions (MPS), an ISO-17025 accredited laboratory specializing in battery characterization and safety testing. The validation focused on the performance of QuantumScape’s single-layer solid-state pouch cell prototypes. 2. Key Performance Metrics and Test Results Cycle Life and Capacity Retention: The cells demonstrated a cycle life exceeding 800 cycles at a 1C/1C charge/discharge rate. After 800 cycles, the capacity retention remained above 80%, meeting a critical benchmark for automotive-grade durability. Fast-Charging Capability: Testing verified that the cells can

How to evaluate lithium-ion battery capacity? Evaluating the capacity performance of lithium-ion batteries is primarily conducted through cycle life testing. The core of such tests is to simulate the battery’s aging process during charge and discharge cycles, while monitoring key indicators such as capacity fading and internal resistance growth. I. Core Testing Method: Cycle Life Testing 1. Testing Principle Cycle life testing is conducted in a controlled environment (regulating temperature and humidity) by subjecting the battery to repetitive charge and discharge cycles to simulate real-world usage. By periodically measuring the battery’s actual discharge capacity and comparing it against the initial capacity, engineers calculate the capacity retention rate or fade rate
