Imagine if the batteries in electric cars could be changed as easily as the batteries in a flashlight or camera. Researchers from the University of California at San Diego and local experts engineering company developing technology that would do it.

American engineers have proposed to use instead of bulky hard to remove the batteries for electric rechargeable batteries from several compact plug-in modules. The researchers have already tested the new technology on the 4-door Volkswagen Golf 2002 release.

This technology completely changes the rules of the game. The idea itself may seem simple, but its implementation requires the solution of some of the technical issues to improve the reliability and practicality of the system, – said one of the sponsors of the project M-BEAM.

Replacement battery packs can also be used as storage for solar installations and portable power generators.


To confirm the viability of its technology, the scientists will make a rally car with removable rechargeable battery packs. On the road the car will make a few short stops, only to change the battery.

This requires a completely different approach to the control of battery power. Storage capacity increases as modules are connected in parallel, which requires careful control of stray current between modules – said the head of the research team, Professor Raymond de Kallafon of the Jacobs School of Engineering at the University of California in San Diego (USA).

A team of scientists is developing algorithms for the evaluation of the charge and current control for concealed body, which is part of the system that controls each battery module. Algorithms provide simultaneous and coordinated work of all battery packs, which differ in terms of the charge, chemical composition, age and state.

Scientists presented their findings in a scientific journal in the forum IFAC World Congress in South Africa. Summary of resource material provided PhysOrg.


Researchers believe that the removable rechargeable battery modules can solve many problems of modern electric vehicles. Hot-swappable battery modules and integration will increase the reserve of which the majority of electric vehicles varies from 110 to 160 miles on a single charge. According to them, regular charging takes too much time (from 4 to 12 hours), and the fast, which lasts only 30 minutes, passes through a battery of powerful current that shortens life and reduces safety.

According to the researchers, the cost of an electric vehicle can be reduced by 10 000 dollars, if you do not build in a battery modules, and lease them. In addition, more than 40 percent of citizens are uncomfortable with the fact that their electric vehicles charged from an electrical outlet that can not be found on the roadside.

Another plug-in modules can be removed from the car and recharge at home. A combination of different types of drives can reduce energy consumption and increase the reserve. Battery modules may also be used in the home system backup power.

Currently, researchers are working to reduce the weight of the battery modules. As well as other systems, this requires a well-developed infrastructure. According to the developers, plug-in modules to be available in any store across the country.

The control system battery provides protection against electric shock. Scientists hope that the new development will change the perception of mobile energy storage for electric vehicles .
