Mobile lithium electricity energy storage multi-function power car diesel power compared with environmental mute on the millisecond timescale, rapid response, solar phase change heat storage material power quality is excellent, and off-grid photovoltaic principle process seamless switching multiple advantages, such as critical loads can be applied to protect electric power supply and distribution network, temporary capacity of power supply, improve the capacity distribution network power not work, and many other scenarios. The vehicle optimization cabinet layout adopts advanced shock damping system, installed and off-grid dual-mode seamless switching software and hardware devices, photovoltaic power generation principle, process and application of water mist fire protection system for the first time, configure the remote monitoring data platform, has formed a number of invention patents. Recently, the solar energy lamp simple circuit diagram comprehensive energy company in jiangsu province and China electric cooperative research and development of new energy research institute research center of mobile lithium electricity energy storage multi-function power car officially released. System with special motor vehicles as the carrier, ontology by special chassis, energy storage lithium iron phosphate batteries, energy conversion systems, intelligent monitoring system, solar phase change heat storage material water mist fire protection system and remote monitoring platform system. Solar hot water circulation system, this is the first domestic mobile lithium electricity energy storage power, solar hot water circulation system can replace diesel generators to participate in power doesn't work, the successful implementation of process load uninterruptible power supply, power distribution network end users can get effective promotion service satisfaction.
