Tesla patent hints at more reliable batteries through ‘dynamic’ management system



It’s no exaggeration to state that Tesla’s business hinges on its own battery technologies. Fortunately for the organization, its batteries are among the very finest in the business now. This is very notable in the case of all Tesla’s electric automobiles, as well as its own energy storage products. In terms of vehicles, Tesla’s battery tech has reached a point where it’s capable of supporting the requirements of circuit forcing, as is true with this Model 3 Performance’s Track Mode. In terms of battery life storage, the high quality and functionality of Tesla’s batteries have been so impressive in South Australia it appears to get started an energy storage motion .

Considering Tesla’s reputation for never staying , however, it’s nearly certain the firm ’s batteries may enhance over time. This was cited by Tesla’s President of Automotive Jerome Guillen to CNBC last November, when he noted that the firm ’s technologies consistently evolves. In his section, the executive noted that “the style of this (battery) cell is not frozen,” indicating upcoming improvements in the near future.

A recently published patent factors to one of these battery tech improvements. Titled “Multi-Channel along with Bi-Directional Battery Management System,” the patent describes a means for Tesla to push the envelope on its own battery management system much further. In the patent’therefore announcement, Tesla noted the rising requirement for battery-based power is putting an emphasis on the operation demands of management systems, which ensure proper operation in a variety of products such as electric vehicles and electricity storage components.

While battery handling systems perform vital functions, the components themselves could be subject to several external elements. In the event of electric automobiles, the machine may be subject to mechanical shock and vibration, varying environmental temperature, multiple power domains and also a large number of interference sources that may deteriorate signals between the centralized management control and multiple battery integrated circuits. Considering batteries are the only power source for electric vehicles, instances involving a failure of this system may render an electric car inoperable. With this in mind, Tesla notes there is a need for a battery management system that’s “more robust and lively. ”

Tesla’s patent clarifies what could be dubbed as a redundant battery management strategy, comprising a primary client coupled inside a multi-channel, bi-directional and daisy-chained communication loop. The electric vehicle manufacturer also outlined a method for differentiating a failure location in a battery management system. Tesla describes these as follows.

“The battery management system could incorporate a host (for example, a microcontroller that manages at a system level) and customers (for instance, battery management integrated circuits that manage battery cells inside the system). In embodiments, the host may be implemented in various structures including the earlier mentioned microcontroller and manages the entire system by transmitting commands and receiving responses from at least one of their customers. Each client may monitor and restrain corresponding battery cells to directly measure the electric and physiological status of the cells, such as voltage, quantity of staying electrical charge and temperature of every cell. For instance, the client 120a may monitor the cells 130a. It’s noted that every client may monitor a different number of cells. The client 120a may perform measurements (e.g., voltage, charge, temperature, etc.) and perform specific functions (e.g., bleed-off charge from a battery mobile, etc). ”

Tesla additionally discussed its rationale supporting its usage of daisy-chain loops because of its battery management system.

“The host and every client may communicate orders and responses using a daisy-chain transmission path loop, in which the daisy-chain loop could incorporate a set of cables that transmit electric signals therethrough. In embodiments, the daisy-chain loop may connect the port of the host to the interfaces of their customers in string so that communication may serially happen on one or many stations inside the loop. “

“The battery management system is able to provide redundant communication paths due to the way it can bi-directionally communicate along the daisy-chain loop and because the 2 channels used over the daisy-chain loop every allow access to completely independent and redundant battery management systems. In particular, the host is able to communicate at a clockwise path around the serially connected customers as well as communicate within an counter-clockwise management across the loop. This bi-directionality permits the host to speak with each client if there is a single failure over the daisy-chain loop. This criterion applies to both stations. ”

Ultimately, Tesla notes that these systems will end in what could be called “dynamic redundancy” round its battery management systems. This, needless to say, could foster a new generation of battery packs that are more reliable than the firm ’s leading batteries.

“One skilled in the art may recognize the usage of a multi-channel signaling system as well as a bi-directional signaling structure inside the battery management system results in dynamic redundancy throughout the machine itself. As an instance, if a primary or secondary circuit should fail on a client, the host may convey a redundant command to the client using a distinct and fully operational channel. The multiple channel structure ensures that even egregious error of an sub-system, like the transmission of spurious data, won’t be able to interfere with normal operation of a mathematical subsystem operating on a different channel. In addition, the bi-directionality of this machine allows for compensation to happen in case of a comprehensive path failure somewhere inside the loop. ”

The last months have seen an influx of published patents for Tesla. One of these comprise an automatic tire inflation method patent that could pave the way for off-road capacities for your firm ’s vehicles, even a smart patent that would allow Tesla to address panel interruptions during automobile assemblya patent that describes coloured solar roof tiles, and just a system that utilizes electric cars as a way to improve automobile positioning.
