The Qin DM-i Super Hybrid does require charging. This super hybrid system offers excellent acceleration advantages when fully charged, and its fuel efficiency in a depleted state is also quite impressive. The engine utilizes split cooling technology, allowing for very precise engine temperature regulation. Relevant information about automotive batteries is as follows: Introduction: Automotive batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to lead-acid batteries, which are mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. Working Principle: It uses a lead plate filled with sponge lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharge, chemical energy is converted back into electrical energy.

As an owner of the Qin DM-i for two years, this car is designed for you to charge it. Before my last long-distance trip, I specifically tested it - the acceleration is exceptionally quiet and smooth when fully charged, while the engine noise becomes more noticeable when the battery is low. However, what surprised me most was its convenience. During the period when there were no charging stations in my neighborhood, I drove for half a month relying solely on gasoline. The system intelligently maintains battery power automatically, with fuel consumption around just over 5 liters, which is still much more economical than traditional gasoline cars. Of course, it's better to charge when possible - after all, in pure electric mode, the cost per kilometer is less than one-tenth of fuel expenses, and fast charging can replenish over half the battery in just thirty minutes.

From a cost perspective, charging is particularly economical. My daily commute is 30 kilometers, and the electricity cost for a month of charging is only 60 yuan, whereas refueling would cost 300 yuan. The DM-i's shallow charging and discharging are also beneficial for lifespan, as prolonged low charge states can negatively impact battery health. The new model now supports fast charging, reaching 80% in just the time it takes to have a meal, making it much more convenient than the older models.

This car can still run without charging, but the experience is significantly worse. When fully charged, the pure electric mode offers zero vibration, with fast and silent acceleration; when the is low, the engine is forced to start, and there's a slight vibration felt in the steering wheel. I've tried not charging for two consecutive weeks, with fuel consumption stabilizing at around 4.8 liters. It's recommended to maintain at least 20% battery level, so the motor can still assist during rapid acceleration.

Charging is better for both the environment and the vehicle. Pure electric driving produces zero emissions, and maintaining a medium to high charge level for extended periods can reduce the number of engine start-stop cycles. My neighbor only refuels without charging, and after half a year, the pure electric range noticeably dropped from 55 kilometers to 48 kilometers. So even without a charging station, occasionally using the portable charger to top up is beneficial. Charging overnight with a household socket can provide enough power for two days of driving.
