On March 10th, Guangqi Yama has sent a new generation of power battery safety technology. The biggest highlight should be the power battery system of three-yuan lithium battery as a module in acupuncture experiment. Will not get fire (only smoke). In the information released by GAC ENA, this power battery system for acupuncture test is based on a ternary lithium battery, but the electrolyte, diaphragm, and module have a large extent around safety demand. Increase.
The final “author has something to say”:
This time, there is no fire burning in the premature process of the magazine battery system. As a result, it does reflect excellent security. However, during the test, the steel needle penetrates the vicinity of the battery housing (or the thermostable battery, or the housing involving the transfer to heat) to 686.7 degrees Celsius, although the manufacturer promotional magazine battery system can bear Up to 1400 degrees Celsius high temperature.
Associated China introduces the latest standards for new energy vehicles to reserve 5 minutes of escape time, the magazine battery can withstand the technical indicators of up to 1400 degrees Celsius, is the thermal out of control with ternary lithium battery system The fire burning accident rate is highly prominent.
It should be noted that the safety of the Guangzhou Automobile ENA Based Battery System is the high temperature resistance of the electrical core (electrode material, diaphragm and electrolytic solution), and a mandatory layer (spacious warehouse pad). High efficiency of high temperature resistance, thermal management control policies (water-cooled plate thermally transfer and fast-derived energy-saving “(24-hour data monitoring active cooling cooling) high efficiency, extroverted from the inside out, soft and hard A synthetic solution.
However, an electric vehicle combustion accident is adapted to different types of battery systems in the past, most of the battery system heat is out of control. In other words, if you want to simultaneously prevent the safety hazards of electric vehicles, you must start from the battery positively sub-aviation quality, voltage, diaphragm, and electrode liquid level. From the “radiation” module, housing, thermal management control strategy and BMS monitoring capabilities of the electrical circle, are auxiliary technical category.
Then the problem is coming, the magazine battery system issued by Guangqi Eman isWhat type of three-yuan lithium battery is used?
1, ultra-high heat-resistant and stable battery:
To ensure that the power battery cell is not thermally out of control. Guangqi Yan’s battery positive material uses nano-scale coating and doping techniques, which can effectively improve thermal stability, and the application of new additives for electrolyte also help to improve the life of the battery, reduce battery short circuit risk, especially It is such an electrolyte additive to greatly reduce thermal out-of-control reaction.
2, super-insulating battery safety cabin:
Guangqi Eman’s new battery technology called the bomb clip battery is therefore true The nanoporous heat insulating material and the high temperature resistant upper housing are directly separated by each of the cells. Realize the heat loss of the three-dimensional lithium battery does not spread to adjacent electrical cells. At the same time, the high temperature resistance of the battery system is also important, and it is guaranteed The high temperature of 1400 degrees Celsius still protects the battery assembly, which is very rare.
3, speed cooling system for speed cooling:
Power battery high power charge and discharge can easily result in rapid increase in battery temperature, especially in hot summer When using high-power charging piles, if there is no reliable battery temperature control system, the chance of battery thermal out-of control will increase, and this time, the splitting battery mentioned in Guangqi Eman, through the full bonding liquid cooling system, High-speed heat dissipation channel, high precision thermal path design, realizing the heat dissipation area by 40%, heat dissipation efficiency increases by 30%, effectively preventing thermal spread.
4, the fifth-generation battery management system of the full-time control:
Can the front three-point technique keep the power battery do not self ignite? It is definitely not, because the integrity of the power battery is inconsistent, and it is inevitable that the power battery does not have a bump touch. At this time, it is necessary to monitor the power battery data monitoring, the ballifier battery is through the latest generation of batteries Managing system chips to achieve 10 24-weather data acquisition per second, monitoring battery status. When an abnormal is found, the battery speed cooling system is immediately started to cool down. Pre-registration to ensure the safety of power batteriesreliable.
Guangqi Ean’s new power battery safety technology is really a bit, but will not cause battery costs to increase the price to the consumer head? The author also consulted the manufacturer, the conclusion of manufacturers is a battery system that is equipped with a magazine battery system security technology. It is 5.7 percentage of weight energy density with respect to the same common battery assembly volume energy density, and the cost is 10%. It is possible to improve the battery capacity and reduce it or use CTP battery technology and nickel 55 batteries. This is the case, and there is a chance to analyze it with you later.
