Control circuit for operating a electrical energy store - A simplified explanation of the abstract
This abstract first appeared for US patent application 18079583 titled 'Control circuit for operating a electrical energy store
Simplified Explanation
The control circuit described in the abstract is designed to operate an electrical energy store by using electrical switching means, a suppressor diode, and an electrical attenuation element to protect the switching means from overvoltage and attenuate transients caused by switching operations.
- The control circuit includes at least one electrical switching means in the current path for charging or discharging current.
- A suppressor diode is connected in parallel to the electrical switching means to protect it from overvoltage when opened.
- An electrical attenuation element is connected in parallel to the suppressor diode to attenuate transients caused by switching operations, especially when the switching means is opened.
- The innovation can be applied to electrical energy stores and electrical consumers, such as hand-held machine tools, with exchangeable battery packs.
Potential Applications
The technology can be applied in various electrical energy storage systems, including portable devices like hand-held machine tools, to enhance safety and efficiency.
Problems Solved
1. Protection from overvoltage when the electrical switching means is opened. 2. Attenuation of transients caused by switching operations, ensuring smooth operation of the system.
Benefits
1. Improved safety for the electrical energy store and connected electrical consumers. 2. Enhanced reliability and longevity of the system components. 3. Efficient operation with reduced risk of damage due to transients.
Potential Commercial Applications
The technology can find applications in industries utilizing hand-held machine tools, electric vehicles, and other portable electronic devices with exchangeable battery packs.
Possible Prior Art
One possible prior art could be the use of suppressor diodes in electrical circuits to protect components from overvoltage. However, the specific combination of electrical switching means, suppressor diode, and attenuation element as described in this patent application may be a novel innovation.
Unanswered Questions
How does the control circuit handle high-frequency transients?
The abstract mentions attenuation of transients, but it does not specify the frequency range or the mechanism used to address high-frequency transients.
What is the expected lifespan of the electrical attenuation element?
While the benefits of the technology include enhanced reliability, the durability and lifespan of the electrical attenuation element are not explicitly mentioned in the abstract.
Original Abstract Submitted
A control circuit for operating an electrical energy store has at least one electrical switching means, arranged in a current path for a charging or discharging current, for interrupting the charging or discharging current and with a suppressor diode, connected in parallel to the electrical switching means, for protecting the electrical switching means from an overvoltage when the electrical switching means is opened. An electrical attenuation element is connected in parallel to the suppressor diode in order to attenuate transients caused by a switching operation of the electrical switching means, in particular by an opening of the electrical switching means. The disclosure also relates to an electrical energy store and/or an electrical consumer with a control circuit according to the disclosure, and to a system consisting of an electrical consumer designed as a hand-held machine tool and at least one electrical energy store designed as an exchangeable battery pack.
