PRODUCT SHOWCASES
🏗️ Product Overview
EW-EMS-P Portable Series is a lightweight energy storage mobile power supply launched by Beijing Engine Welder Technology Co., Ltd. for field low-power operations, emergency repairs, communication support and other scenarios. The whole machine adopts a compact trailer cabinet design, which is small in size, light in weight, and can be towed and deployed by a single person. With zero emissions and low noise, it is the preferred cleaning power solution to replace small diesel generators.
The whole machine is equipped with liquid cooling temperature control and pack grade gas fire protection. The protection level is IP54 and C4 industrial anti-corrosion. It can operate stably at -20 ℃ ~ +50 ℃ and 0 ~ 95% RH humidity.
⚙️ Key Advantages
- Compact and lightweight, flexible deployment: Machine size ≤ 2640 × 1500 × 1960mm, self weight ≤ 4.5T, trailer chassis, can be transferred and deployed by one person, no lifting equipment required
- Lithium iron phosphate safety cell: 314Ah high-capacity LFP cell, excellent thermal stability, cycle life 8000 times (0.5C charge and discharge, 70% capacity retention rate)
- IP54 + C4 anti-corrosion: Adapts to harsh environments such as high humidity and salt spray, and works outdoors 24/7
- Pack Grade Gas Fire + Liquid Cooling Heat Dissipation: Reasonable cell temperature difference control and reliable thermal management
- 系统效率 >85%: Efficient energy conversion to reduce long-term operating costs
- CE + Marine Certification: The P241 model supports overseas exports and meets the needs of international projects
