1. Multi-mode common rail system technology is to decompose the traditional single vehicle system into multiple independent standardized small power modules, so that the vehicle electrical system has full power, modularization, multi-unit, distributed, high reliability and strong fault tolerance and other features to achieve cost reduction and efficiency increase and intelligence;2. For complete vehicle companies, the multi-mode common rail power system can effectively reduce the R&D, procurement and production costs of the company, while reducing costs, it can also improve the performance of the complete vehicle, and the stability of the complete vehicle is better;3. It is more conducive to the battery replacement mode of vehicle-electricity separation, reducing the cost of consumers' car purchases;4. Improve the use environment of lithium batteries, making lithium batteries safer, with longer service life and stronger battery life;5. For consumers, it is safer, more comfortable and more convenient to use a car.
