BYD Qin PLUS EV blade (lithium iron phosphate) power battery is selected, the single battery is 3.2V135AH, the aluminum shell is as square as a blade, and there are 2 single blade cells. It can measure voltage and internal resistance, and train students to master the basic knowledge of BYD blade (lithium iron phosphate) battery.
ii. Features
1. The single battery is placed on the platform. With the help of a digital multimeter, students can measure the voltage of the single blade battery. Understand the 3.2V voltage platform and basic parameters of the blade (lithium iron phosphate) battery.
2. With the help of the self-provided charger, the single battery can be recharged.
3. With the help of the internal resistance tester, students can measure the internal resistance of the undissected blade (lithium iron phosphate) battery.
4. The training bench is composed of a platform and a teaching board. The teaching board is placed vertically, and a three-dimensional composition structure diagram is drawn to introduce the basic knowledge of this type of single battery, so that students can quickly master the basic parameters of the blade (lithium iron phosphate) power battery.
5. The training platform has four casters, which can move flexibly. At the same time, the casters have self-locking device, which can fix the position.
6. The training bench is equipped with a complete cutaway blade (lithium iron phosphate) single battery, which truly reproduces the internal structure of the blade (lithium iron phosphate) battery, allowing students to truly see the components of the blade (lithium iron phosphate) single battery.
7. The training bench is equipped with a teaching resource package software V1.0. Using three-dimensional animation mode, the internal structure of the blade (lithium iron phosphate) power battery cell is described in detail. Each main component can be opened, and has basic parameters and performance descriptions. The intelligent courseware is installed with a U disk, and can be played directly after being inserted into the computer, which is suitable for practical teaching.
