Break through the traditional power battery testing thinking-IT6000C two-way programmable DC power supply

With the globalization of the concept of green travel, the sales of new energy vehicles are increasing year by year. By 2025, the global sales of new energy vehicles will increase to 11 million, and it will continue to climb to 30 million in 2030. As the core part of new energy vehicles, the reliability and endurance of power batteries are directly related to the development of new energy vehicles. Therefore, the test of power batteries is urgent. In the power battery testing industry, solutions such as “high-power resistance discharge” or “DC power supply + DC Electronic load” can surely meet today’s power battery testing needs? The answer must be say no.

Therefore, the test of power batteries is urgent. In the power battery testing industry, solutions such as “high-power resistance discharge” or “DC power supply + DC electronic load” can surely meet today’s power battery testing needs? The answer must be say no.

As a professional instrument manufacturer, ITECH has launched the latest power battery charging and discharging test program, which not only breaks through the traditional thinking from the hardware architecture solution, but also helps users save the cost of high power consumption; it also aims at the unique power battery in the software function. Work mode, increase the communication interaction of BMS.

Breakthrough 1: IT6000C two-way programmable DC power supply-energy feedback, green and energy-saving

With the development of batteries, from the original 1.5V dry battery to the power battery up to 800V/50KW, there are roughly three scheme models: DC power supply + high-power resistance box, DC power supply + energy-consuming electronic load, DC power supply + Regenerative load, but ITECH does not introduce any of the above solutions, but a brand-new two-way programmable DC power supply that integrates bipolar power supply and regenerative load functions with only one IT6000C. .

(1) Compared with the source-load separation scheme, the two-way feedback power supply has the advantage of power battery testing?

The power battery is the power source of the car. Of course, there is a complete braking energy recovery system on the car. When the battery is running, the battery is discharged; the energy recovered during braking charges the battery in the reverse direction. Imagine the situation of daily driving and going out, often starting or braking, the actual power battery curve is as shown in the figure below, the current has a source and a sink, and it is converted to the battery test. If the city conditions are simulated, the test will be charged and discharged from time to time. Switch quickly.

At this time, the IT6000C solution has a great advantage and can realize fast current switching. However, if the source + electronic load is implemented, two devices need to be controlled, and the control switching takes time, which will affect the speed of current switching, so it cannot be regarded as the optimal power battery test program.

In the same way, such a set of equipment can be used not only as a power battery test device, but also as a simulated power battery device to test other energy management systems for vehicles.

(2) The energy feedback efficiency is as high as 95%, saving electricity costs

In the general battery discharge test, the energy is dissipated in the form of heat by the electronic load or resistance box, resulting in a waste of resources. If this part of the energy is converted into electrical energy for use by other equipment, it can help users save a lot of money. An electricity bill. IT6000C series power supplies have an energy feedback efficiency of up to 95%, which saves energy and avoids fan noise caused by traditional solutions due to heat dissipation.

Breakthrough 2: High power and small size, saving laboratory space

The power of the power battery is generally as high as 40KW~50KW. If a set of charging and discharging equipment is equipped according to the traditional scheme, it will occupy about 3 37U cabinets. Using IT6000 series equipment, taking 15KW as an example, the volume can be reduced to 3U. , Which greatly saves laboratory space.

ITECH IT6000C series two-way programmable DC power supply, with its comprehensive functions, excellent performance and rich supporting software capabilities, successfully breaks through the traditional power battery testing thinking, and greatly reduces the testing space, saves electricity costs, and reduces The operational complexity of the test platform greatly improves the reliability and safety of the overall system. Easily restore your environmentally friendly, cool and green test environment!
