【Chemical Machinery and Equipment Network Market Analysis】Since the release of the "Energy-saving and New Energy Vehicle Technology Roadmap 2.
0" in 2020, the enthusiasm of the industry to develop hybrid technology has been rekindled in a very short period of time, and by the end of 2021, almost all mainstream self-owned brand car companies have launched their own hybrid system architecture, such as Great Wall Motor's lemon hybrid DHT; Changan Automobile's Blue Whale iDD; Geely Automobile's Raytheon Zhiqing Hi· X hybrid system, etc
.

The entry of mainstream car companies has made the once somewhat "lonely" hybrid models suddenly become lively
.
And from the feedback of the market, hybrid is also going all
the way.
According to the latest data released by the China Association of Automobile Manufacturers, from January to July 2022, the cumulative sales of plug-in hybrid vehicles in China reached 674,000 units, a year-on-year increase of 1.
7 times, higher than the growth level
of pure electric vehicles of 1 times.

Hybrid, which is more popular with consumers

In fact, from 2021, the growth rate of hybrid vehicles began to be higher than that of pure electric vehicles, and this growth rate began to expand
further in 2022.
Some analysts pointed out that the rapid growth of the hybrid vehicle market is the result of
industrial competition.
Because compared with pure electric models, hybrid models without range anxiety and more cost advantages are more likely to win the favor
of consumers.

At present, although the cruising range of most pure electric vehicles has exceeded 500km, range anxiety and charging anxiety are still lingering shadows for consumers
.
Plug-in hybrid models have both pure electric and hybrid modes, and their comprehensive cruising range is often twice
that of pure electric models.

In terms of cost, since the beginning of this year, new energy vehicle subsidies have further declined, and at the same time, due to the sharp rise in the price of battery raw materials, pure electric vehicles have staged multiple rounds of price increases, ranging from thousands of yuan to tens of thousands of yuan, which makes consumers' car purchase costs skyrocket
.
In contrast, the acquisition cost of hybrid models with less power will be relatively lower
.
At the same time, the subsequent battery maintenance and maintenance costs of hybrid vehicles will be lower
.
In addition, under the continuous high operation of oil prices, the cost of use of hybrid vehicles will be much
lower than that of fuel vehicles.

Of course, many people believe that compared with electric vehicles, the core advantage of hybrid models is not in terms of cost, but in terms of basic support, in the case of electric vehicle charging infrastructure is not perfect, hybrid models are one of the high-quality options to meet the convenience of
consumers.

Very different hybrid battery

Obviously, at a time when the energy density of the battery is difficult to greatly increase, and the problems of charging difficulty and slow charging are becoming increasingly prominent, hybrid can better meet the actual needs
of consumers.

At present, hybrid models have a variety of power types
such as mild hybrid, gasoline-electric hybrid, plug-in hybrid and range extender.
However, no matter what form it is, the requirements for power batteries for hybrid models are very different
from those of pure electric models due to different architectures.

First of all, in order to ensure that the engine always runs in the most fuel-efficient and economical working conditions, hybrid models have high requirements for the charging and discharging performance of power batteries
.
In contrast, the battery discharge rate of general pure electric vehicles is about 1~3C, while the discharge rate of hybrid vehicle batteries should reach 10C
.

Secondly, in pure electric mode, the mileage of hybrid vehicles is generally 50-200km, and the power is generally not large
.
However, under the same driving range, hybrid batteries require more times to charge and discharge than pure electric models of the same class, so the cycle life of the battery is required
.

Overall, the core requirements of pure electric vehicle power batteries are energy density, cost and safety, and what is needed is an energy-density battery with sustainable output; Hybrid models pay more attention to the instantaneous power, pulse cycle life and low-temperature starting performance of the battery, and need a more instantaneous explosive power battery
.

Ultra-high power lithium-ion battery

In the face of the differentiated needs of the market, Sandton New Energy Technology Co.
, Ltd.
(hereinafter referred to as "Sandton New Energy") keenly laid out the segment of high-power batteries, and after more than three years of technical research and repeated experimental verification, successfully developed ultra-high-power lithium-ion batteries and systems
with independent intellectual property rights.

It is understood that the cycle life of Sandton New Energy ultra-high power lithium-ion battery system exceeds 10,000 times, which is far better than the current power batteries on the market, which can meet the requirements of hybrid models for battery cycle life to the greatest extent, and can also extend the user's battery replacement cycle and save use costs
.

It is worth mentioning that Sandton New Energy ultra-high power lithium-ion battery has both fast charging and fast discharge capabilities
.
The battery can be fully charged within a few minutes, greatly reducing the user's energy replenishment anxiety, which is more obvious
in the 800V high-voltage fast charging platform that car companies are currently pursuing.
In addition, the continuous discharge rate of the battery can reach 70C, which is dozens of times that of electric vehicles on the market at present; The pulse discharge power capacity reaches 7000W/kg, which is dozens of times that of ordinary batteries, even under low-speed road conditions, it can fully meet the power request of the drive motor and quickly release electric energy
.

Of course, the large current required for fast charging of power lithium batteries will also bring safety risks such as thermal runaway, so Sandton New Energy has made improvements
in the thermal management system and heat dissipation system of the battery.

In terms of system design, Sandton New Energy adopts the industry's first liquid cooling system integration + superconducting vapor chamber thermal management integration scheme, the heat exchange efficiency is 2~4 times higher than that of the traditional liquid cooling system, effectively solving the temperature rise problem of the battery system at high rate, the system supports continuous 5C and peak 10C discharge, and the temperature can be controlled under all-weather working conditions of no more than 40 °C
.

In terms of module process, Sandton New Energy has standardized module stacking, and thermal runaway protective materials are used to partition between modules to achieve no thermal diffusion
in the battery system.
The system also has the functions of active early warning and passive protection of thermal runaway to ensure the safe and reliable operation
of the whole life cycle of the system.

Seize the opportunity of hybrid batteries

As an innovative enterprise specializing in providing lithium battery energy R&D and production solutions, Sandton New Energy has formed a complete industrial chain layout
from core materials to power batteries since its establishment in 2011.
In 2018, Sandton New Energy was the first in the industry to mass-produce ternary soft pack cells with an energy density of 260wh/kg, making it a "dark horse"
in the field of new energy power batteries.

With years of deep cultivation in the field of lithium-ion power batteries, Sandton New Energy closely follows the market demand, continuously improves technical capabilities and optimizes product solutions
.
The ultra-high-power lithium-ion battery launched this time will not only greatly meet the needs of hybrid models, but also seek more share
for it in the power battery market.
It is reported that the battery system has been installed on a large domestic car factory and will be officially put on sale
soon.

At present, the industry generally believes that hybrid vehicles are in the stage
of gaining momentum.
Focusing on China, driven by the "3060 dual carbon" goal, the direction of the automotive industry towards energy conservation and electrification has been further clarified
.
In the "Energy-saving and New Energy Vehicle Technology Roadmap 2.
0" released in October 2020, it is clearly mentioned that by 2035, China's annual sales of energy-saving vehicles and new energy vehicles will each account for half, and all traditional energy-powered passenger cars will be converted to hybrids, so as to realize the comprehensive electrification transformation
of the automotive industry.
This is also one of the
reasons why many Chinese car brands mentioned at the beginning of the article are actively deploying hybrids.

According to this, CITIC Securities Research Report pointed out that at present, China's hybrid vehicle market has gradually transitioned to the consumption-driven stage
.
In the long run, hybrid vehicle sales are expected to reach 4 million units in 2025, accounting for 30%
of the new energy passenger vehicle market.
In the context of the rapid increase in the penetration rate of hybrid models, companies related to the industrial chain are expected to continue to benefit, and Sandton New Energy, which is actively deploying in the field of power batteries, will obviously take the lead
.
