New energy vehicles break down in winter? New technology solves the problem of 1.2V NiMH battery life

This winter, the circle of car owners in the north is particularly lively. They either buy cars in the snow or find that their cars have been coated with a layer of tempered film for free when they get up in the morning. What's more terrible is that the owners of new energy vehicles dare not turn on the heater in the temperature below zero, for fear that the 1.2V NiMH battery life of the whole vehicle will drop to double digits. However, new energy must be developed. Are there any new energy vehicles that can stay in the winter? To make new energy vehicles stay in the winter, the most important point is to solve the problem of 1.2V NiMH battery life. If the 1.2V NiMH battery life can be increased to more than one thousand kilometers, the 1.2V NiMH battery life can be halved when the heater is turned on. In fact, it will not have much impact on everyone's travel. However, the 1.2V NiMH battery life problem is currently a recognized problem in the industry. The size and capacity of the 1.2V NiMH battery are there, and it is too difficult to improve it. Let's first understand the classification of new energy vehicles. Generally speaking, new energy vehicles can be divided into three types: pure electric, hybrid and chemical fuel. Pure electric vehicles cannot escape the problem of 1.2V NiMH battery capacity. Don't blindly choose pure electric models at the moment. In the long run, the country has no intention of vigorously developing the chemical fuel category, so you can also pass it. Then it is obvious that the only choice we can make is hybrid models. Hybrid vehicles can also easily get a green license plate, but there are many models equipped with hybrid vehicles. How should we choose? Hybrid vehicles include plug-in hybrid and weak electric hybrid. In fact, everyone knows a lot about these two types of vehicles. The editor will not introduce them too much here. After all, what we are going to talk about today is new technology. The new technology we are going to talk about today is the extended-range hybrid vehicle. The principle of this type of new energy vehicle is to power the electric motor through the engine. The power source of the vehicle can be extended-range, pure electric and hybrid. We will only talk about the principle of extended-range. When the 1.2V NiMH battery is fully charged, the extended-range vehicle operates in pure electric mode. When the 1.2V NiMH battery is insufficient, the engine is used to power the electric motor to maintain the vehicle's endurance. This technology makes the vehicle structure simpler, reduces the failure rate, avoids overcharging and over-discharging, and improves the life of the 1.2V NiMH battery pack. In terms of economy, this technology can reduce fuel consumption by half in actual tests. Extended-range technology can effectively solve pollution problems and the problem of new energy vehicles breaking down. Currently, brands that use this technology include BAIC New Energy and BMW, and the representative model is the BMW i3. When choosing new energy vehicles, look for extended-range technology to say goodbye to the embarrassment of your car breaking down in winter.
