Battery testing system for power banks

Battery testing system for power banks(BTS-4000-6V4A-CCDC-USB) is based on Neware BTS4000, it shares all the main feature of BTS4000, such as 0.05%FS accuracy, 10Hz data acquisition frequency, based on Ethernet communication, etc.

In another way, as a testing system for power banks, it has its own special features:

1. There are 8 channels for each set, but as you can see from the above picture, each channel consists 3 USB port(1 standard USB port for charging, and 2 Micro USB ports for discharging, the maximum output current can be up to 4A, according to the currently popular power banks, normally there are 2 outputs Micro USB ports, one is 1.5A and another is 2.5A);

2. The best matched software for BTS-4000-6V4A-CCDC-USB is BTS7.5.3. And here are 2 example scripts for testing power banks by using BTS-4000-6V4A-CCDC-USB.

Tests operation notes of BTS-4000-6V4A-CCDC-USB need attention

1. For power banks charging step, generally use "CV-constant voltage charge", and for power banks discharging step, please use "CR-constant resistance discharge"(for the 2A Port please set up the resistance value as 2.5Ω, and for the 1A Port please set up the resistance value as 5Ω).
2. When start up power banks tests, please don't set up protection in the BTS software, cause mostly power banks have its own protection board;
3. For regular battery tests, the cut-off current is necessary for CV charge, but for power banks, because of its own protection board, so we don't need to set up the cut-off current. In this case, please modify the value of CVCCHARGEMODE in BTS.INI to 1. Operation guide: Please close the BTS application firstly, go to the installation directory(normally C:\Program Files (x86)\NEWARE\BTSClient7.5.5) and open the BTS.ini file.
Locate the following segment and modify the value from 0 to 1.
[CVCHARGEMODE]
MODE=1

BTS4000 is based on Neware 4th-generation testing system, and was introduced into the market in 2008. It's the upgrade version of the most popular battery test equipment series of BTS3000.

BTS4000 applies all the applications of BTS3000, plus EV battery pulse test, HPPC test and DCIR (direct current internal resistance) test.

Comparing with BTS3000, BTS4000 greatly improved the hardware response time, data acquisition frequency and result accuracy.

BTS4000 is the perfect test system in Neware's line of high quality, dependable test systems.

BTS4000 can be configured with multi-current range channels, which have a current control range of 0A to 3000A. These multi-current range channels can be configured for voltage ranges of 0V to 110V. The accuracy for current and voltage on these channels is ± 0.05% FS.

BTS4000 is now widely used by research institutes, colleges and universities and EV battery manufacturers all around our country.

The Picture on the left side is a high power BTS4000 with 2 channels.

The highest power of BTS4000 can be up to: 5V3000A or 60V500A or 110V180A

Typical high power model of BTS4000 could be: 60V20A-4CH, 60V40A-2CH, 60V60A-2CH, 60V100A-4CH, 60V200A-1CH, 60V300A-1CH, 60V500-1CH, 110V100A-1CH, 110V180A-1CH.

For the clients who use Neware BTS3000, problems arise when they use upgraded version BTS4000,especially when it comes to the software operation. The channel can only be seen through “mapping”. Today, let’s talk about channels mapping in BTS4000.

Step 1: Start software, you’ll notice none of the functions can be used before you log into the client account. Choose from menu “user -> User Login” and log into the system with user name‘admin’ and password ‘neware’.


Step 2: Right click in the main working area, choose “reset map”.


Step 3: From the popped-up “Set mapping” window, double-click the last node, the relevant channel will appear.
Step 4: Drag the channel one by one to the right window with the mouse. If there are too many channels,click right on the right working area, then choose “The Main Channel Default Mapping->1*8”, and all the channels will be mapped successfully.



Step 5: Right click and choose “Save Map”, then the data of channel mapping will be saved.


Step 6: Return back to the main interface of the BTS software,all the channels of the equipment can be seen. And you can start test by right clicking on any of the channels.

Of course, here's the mapping video of BTS4000, you can definitely learn how to map channels in BTS4000.

While electric vehicles offer many advantages--including reducing greenhouse gas emissions and the country's dependence on imported petroleum--at least one barrier stands in the way of their large-scale adoption: "range anxiety." The current 2014 electric Nissan Leaf, for example, has a range of just 84 miles on a fully charged battery. With support from the National Science Foundation, researchers at George Washington University, led by Stuart Licht, think they have developed a novel solution, and they're calling it the "molten air battery." It could extend EV range by a factor of 50, up to 4,000 miles or more on a charge.

These new rechargeable batteries, which use molten electrolytes, oxygen from air, and special "multiple electron" storage electrodes, have the highest intrinsic electric energy storage capacities of any other batteries to date. Their energy density, durability and cost effectiveness give them the potential to replace conventional electric car batteries, said Licht, a professor in GWU's Columbian College of Arts and Sciences' Department of Chemistry.

The researchers started with iron, carbon or vanadium boride for their ability to transfer multiple electrons. Molten air batteries made with iron, carbon or vanadium boride can store three, four and 11 electrons per molecule respectively, giving them 20 to 50 times the storage capacity of a lithium-ion battery, which is only able to store one electron per molecule of lithium. "Molten air introduces an entirely new class of batteries," Licht said.

Other multiple-electron-per-molecule batteries the Licht group has introduced, such as the super-iron or coated vanadium boride air battery, also have high storage capacities. But they had one serious drawback: They were not rechargeable. Rechargeable molten batteries (without air), such as a molten sulfur battery, have been previously investigated, but are limited by a low storage capacity.

The new molten air batteries, by contrast, offer the best of both worlds: a combination of high storage capacity and reversibility. As the name implies, air acts as one of the battery electrodes, while simple nickel or iron electrodes can serve as the other. "Molten" refers to the electrolyte, which is mixed with reactants for iron, carbon or vanadium boride, then heated until the mixture becomes liquid. The liquid electrolyte covers the metal electrode and is also exposed to the air electrode.
