Counterfeit battery packs look almost identical to genuine ones and are usually cheaper. But many counterfeit batteries lack safety components or protective devices, and these are the proof of the quality of genuine batteries. For example, genuine lithium-ion battery packs typically use primary batteries with safety precautions to prevent overshoot, overdischarge, overcurrent protection circuits, and isolation overcurrent protection devices. The battery in the gray market not only poses a huge risk to consumers, but also causes original equipment manufacturers (OEMs) to lose their revenue sources. However, it is difficult for the counterfeiters to eradicate, and related issues have been repeatedly banned. In FY2017, the US Customs and Border Protection (CBP) seized and destroyed nearly 32,000 fakes, a 52% increase from 2014, including a wide variety of items, not just counterfeit batteries. However, as CBP pointed out in its November 2017 blog: “The counterfeiters always focus on counterfeiting popular products such as smartphones or cosmetics. Maybe you remember the suspension board from late 2015 to early 2016. The boom, many of which use counterfeit batteries, eventually cause fires and pose serious safety hazards." In fact, consumer electronics is the second-largest pirated product in the US, so it's no surprise that counterfeit batteries have become a major problem. According to Scout CMS blog post, smartphone batteries are attractive to consumers who are cheap, "But the downside is that the complex design of smartphone batteries can cause failures - even without hacking." A simple and economical anti-cloning method Did you know that the battery fuel gauge IC can prevent counterfeiting and is very simple and economical? The fuel gauge IC with integrated SHA-256 security certification protects against counterfeit batteries in a variety of end markets, including finance, consumer, medical, computing and gaming. The secure authentication feature in the fuel gauge uses a unique key to prevent the creation of illegal copies, making it less useful to steal keys from a single IC. ICs with multi-step key generation provide a very good way to prevent manufacturing site leak keys. It is best to generate the key by challenge-response instead of writing directly to the IC. To further protect against key theft, the IC should be able to withstand optical, electrical, timing, and power analysis, as well as physical detection through reverse processing. Maxim's MAX17201, MAX17205, MAX17211, and MAX17215 ModelGaugeTM m5 fuel gauge ICs fully meet these safety certification standards. These FIPS 180-4 compliant ICs have a SHA-256 security certificate and a 160-bit key. The factory uses a multi-step key generation method to generate a unique key for each battery, as shown in Figure 1. First, Secure1 is generated using a secure hash algorithm, and then Secret2 is generated using the same hash algorithm and the unique ROM_ID of the chip. Secret1 is overwritten, and Secret2 is stored in the IC, and each IC is different. Battery pack manufacturers do not need to know Secret1 or Secret2 to minimize the risk of key compromises and the two separate challenges used are safe at the factory. Figure 1. Diagram showing a unique key for each MAX172xx fuel gauge IC Figure 2 shows the process of securely authenticating the battery in the host software. The host software generates Secret2 using Challenge2, Secret1, and ROM_ID. The host software then performs a challenge-response method for security authentication to verify that the fuel gauge knows Secret2. The host software must guarantee the secure storage of Challenge2 and Secret1. Figure 2. Graphical host software performs safety certification on the MAX172xx fuel gauge IC These fuel gauge ICs are designed to prevent theft of keys from the IC. The key cannot be physically read from the fuel gauge and can only be verified by challenge-reply. As a counter measure against reverse processing, the IC has optical detection immunity. 1 and 0 stored in non-volatile memory are physically indistinguishable. The fuel gauge IC is capable of withstanding electrical detection, such as microprobes and electron beam probes, because the keys are not stored in clear text in non-volatile memory. Its physical design uses a top metal layer to conduct power, ground and other signals without critical information. Critical information is covered by electrically offset metal areas. If someone tries to remove the top metal layer, this action will cause the chip to not work. The confidentiality of all signal layers cannot be found intact, whether it is micro-detection or voltage contrast. The IC can also prevent timing analysis and power analysis (the timing of the SHA calculation is independent of the key, and the power consumption during the internal key access is independent of the value of the key). In addition, timer values ​​are stored in the Life Record Register to provide countermeasures against cloning. High precision without battery characterization The MAX17201, MAX17205, MAX17211, and MAX17215 ICs use the ModelGauge m5 EZ algorithm to achieve high accuracy without battery signature analysis. The ModelGauge m5 Ez algorithm combines the excellent short-term accuracy and high linearity of the Coulomb counter with excellent long-term stability of the voltage fuel gauge and temperature compensation. The IC automatically compensates for aging, temperature, and discharge rates over a wide range of operating conditions and provides accurate state of charge (SOC) in milliampere-hours (mAh) or percentage. Prevent your battery from being shammed - choose a fuel gauge IC that not only provides the accuracy you need, but also prevents cloning, hacking, and other illegal behavior.
