Introduction Is “electric lock” a life-saving option for purely electric vehicles to protect themselves? This is a pain for the car owners who trust them the most. The path ahead of consumers who want to purchase new energy models suddenly appears at a crossroads.

Is “electric lock” a life-saving option for purely electric vehicles to protect themselves? This is

The road ahead for consumers to purchase new energy vehicles suddenly finds itself at a crossroads. One is the long delivery cycle, and the other is the power supply which is secretly and ruthlessly locked by the manufacturer. Can new energy vehicles still be viably purchased? Car owners who have purchased new energy vehicles look up to the sky and sigh: Why don't manufacturers respond? No reminder?

How to improve battery energy density to solve users' range anxiety?

Currently, the most common batteries on the market are ternary lithium and lithium iron phosphate, and everyone should be aware of their characteristics. Ternary lithium battery will increase energy density under different ratios of raw materials and will cooperate with the battery thermal management system to safely ensure the daily use of the power battery. Most models equipped with ternary lithium batteries have a pure NEDC electric range of more than 500 kilometers, and some can even claim to have a range of 700 kilometers. But lithium-ion is a “bad boy”. He is very active and disobedient. No matter how advanced your thermal management system is, overloading it will cause it to become more active, eventually causing the "BOOM" to catch fire and explode. the car was gone, even other people's cars were gone.

When promoting battery capacity, manufacturers usually mention the maximum value, but rarely mention the safety value. After all, cruising range is the biggest selling point for electric vehicles. For example, the battery capacity of the BMW X1 plug-in hybrid is officially called 24 kilowatt hours, but the actual usable capacity is 18.5 kilowatt hours. The capacity is low and the cruising range is naturally low. 30% Purely Electric cruising range is definitely 30% off.

However, these are plug-in hybrids, and when the battery is flat, there is still an internal combustion engine to back them up. However, pure electric vehicles do not have an internal combustion engine to replenish the power. and users can only rely on fast and slow charging to recharge. How the battery management system safely distributes current to each cell can effectively prevent spontaneous combustion. Although many manufacturers have started to comment on battery cases and use safer materials inTo create “armor” level cases, the impact of the lithium-ion blast is quite powerful. “Conservative” manufacturers usually set a narrow range for safe battery capacity values, and deep discharge can be around 60%. In order to make the cruising range figures look good, the “radicals” can set the deep discharge at 80% or 90%, or even up to 95%. Therefore, whether it is traditional car companies or new car companies, they suddenly discovered at some point that as long as users cannot overcharge, lithium ions can be retained more effectively through the management system battery thermal. The “electric lock” skill was therefore activated, so that the huge cost of recall would not be incurred.

Use “Power Locking” to share rising manufacturing costsion of raw materials?

Whether it is traditional car manufacturers or new car manufacturing forces, using "locked power" to ensure the safety of ternary lithium batteries is a bad idea. They were “kidnapped” by. , in order to prevent the battery pack from catching fire and exploding, and thus causing subsequent recall costs, "locking the power" to reduce the risk is the most immediate solution.Yes, but reducing battery life is also very obvious, which is inconsistent with the initial propaganda. Generally, manufacturers "lock electricity" secretly, using the strategy of boiling frogs in hot water to accomplish the task of "lock electricity" invisibly.

The increase in raw materials is caused by the global environment and is inevitablee. The price of nickel metal exceeded $100,000 per tonne for the first time in early March on the London Metal Exchange in the United Kingdom, setting a record high. The increase in raw materials will inevitably lead to an increase in battery cell prices. As battery suppliers increase prices, batteries, as the most important components in the manufacturing process of new energy vehicles, will affect manufacturing costs.

Here we have to talk about the Weimar brand. Initially, Weimar can also choose from four battery suppliers: Ningde, Gushen, Lishen and Suzhou Yuliang, mainly to provide more choices for consumers. However, as raw materials increase, “Ningwang” raises prices first. As a new force in automobile manufacturing, WM Motor is bound to suffer financial losses and cannotunable to bear the surge in costs caused by rising prices. From self-selection of battery cell suppliers to “what I use, you use”? The integrity of the Weimar brand has collapsed.

Not only can WM not bear the increase in supplier prices caused by the increase in raw materials, but GAC Aian also cannot bear it. Their charger battery cells have been replaced with CATL lithium batteries and several others. no choice but to "power lock" just to ensure the product is safe and does not explode.

Conclusion:

Consumers have become the “victims” of rising raw material prices and product recalls that manufacturers secretly “lock down” for safety reasons, which results in shorter and shorter batteries. the life. Very bad feeling. Electric vehicle usersNortherners will experience a more difficult driving environment in the future, while users in the South will actually have more peace of mind if they choose lithium iron phosphate batteries if they are not chasing battery life.
