With the continuous progress of science and technology, the application of armored vehicles in the military field is becoming more and more extensive. However, the problem of starting the power supply of armored vehicles in low temperatures is also becoming more and more prominent. In order to solve this problem, this article will introduce a scheme of low-temperature starting power supply for armored vehicles and evaluate its performance.
1. Low-temperature starting power supply scheme for armored vehicles.
1.1 Program Introduction.
Armored Vehicle Cryogenic Starting Power Supply is a kind of starting power supply specially designed for armored vehicles, which uses advanced battery technology and a unique heating system to quickly start the engine of armored vehicles in a low temperature environment. The power supply is mainly composed of a battery pack, a heating device and a control unit.
1.2 How it works.
The working principle of the cryogenic starting power supply for armored vehicles is as follows:
1) Battery pack: This power supply adopts advanced lithium-ion battery technology, which has the characteristics of high energy density, long life and fast charging. In a low-temperature environment, the battery pack is preheated by a heating device to improve the activity of the battery.
2) Heating device: The heating device adopts the electric heating method, and the heating power is adjusted through the control unit, so that the battery pack can be heated up quickly in a low temperature environment. At the same time, the heating device can also preheat the engine to further improve the success rate of starting.
3) Control unit: The control unit is the core part of the low-temperature starting power supply of armored vehicles, which is responsible for monitoring the temperature and power status of the battery pack, adjusting the power output of the heating device, and controlling the entire starting process.
2. Evaluation of the performance of low-temperature starting power supply for armored vehicles.
To evaluate the performance of the low-temperature starting power supply for armored vehicles, we conducted the following experiments:
Experiment 1: Cryogenic priming experiment.
We placed the cryogenic starting power supply of the armored vehicle in a simulated low-temperature environment and recorded its start-up time at different temperatures. The experimental results show that the start-up time is gradually extended with the decrease of temperature. However, below -20, the power supply can still maintain a fast start-up speed. Table 1 shows the specific data

Experiment 2: Reliability experiment.
In order to evaluate the reliability of the cryogenic starting power supply of armored vehicles, we conducted several starting experiments at different temperatures and recorded the success rate of each experiment. The experimental results show that the success rate decreases gradually with the decrease of temperature. However, below -20, the power supply can still maintain a high success rate. The specific data are shown in Table 2

Experiment 3: Comprehensive performance experiment.
In order to comprehensively evaluate the performance of the low-temperature starting power supply of armored vehicles, we conducted a series of experiments in the simulated harsh environment, including low-temperature start-up, high-temperature start, continuous start, and continuous power ** tests. The experimental results show that the power supply has good comprehensive performance and can maintain stable start-up effect in various harsh environments.
III. Conclusion. In this paper, a scheme of low-temperature starting power supply for armored vehicles is introduced, and its performance is evaluated. The experimental results show that the power supply can quickly start the engine of the armored vehicle in the low temperature environment, and has high reliability and comprehensive performance. Thus, this scheme can be used as an effective solution for solving the problem of starting armored vehicles in a cryogenic environment.
