Tadiran presenteert de 6e generatie Pulseplus HLC

Tadiran presents the latest in its PulsesPlus HLC battery range, doubling power output on its previous offering.

Recently Tadiran launched the C-type HLC which represented a huge improvement from a power perspective in comparison to former generations. Now Tadiran presents the P6 generation, small sized HLC-1020P6 which again doubles the power capability of the renowned PulsesPlus battery.

This technology enables a small component in a ½ AAA form factor to deliver power for all available radio protocols together with additional advantages: It needs less installation space which is especially important for IoT applications (small smart sensors). Secondly, smaller cells with the power of considerably larger products are just more cost-efficient.

Requirements for an electric energy source in the metering and IoT industry are demanding. Despite a long lifetime of up to 20 years these de-centralised systems have the need to cover high current peaks of various radio protocols existing in the market. To provide a reliable solution for this industry, Tadiran invented the PulsesPlus technology around the Millennium which combines an ultra-low self-discharge lithium thionyl chloride battery with a hybrid layer capacitor (HLC). The battery stores the energy while the hybrid layer capacitor is providing the power for pulses.

Both components are made from high quality raw materials refi ned in a precisely engineered manufacturing process.

The result is a perfect-match power supply for any long-term application in even harsh environments.

Nevertheless, there is always room for improvement to add value to the market by new innovative solutions. Consequently, in the past the lithium thionyl chloride system was optimised in capacity, self-discharge and voltage loss. The time was therefore right to focus research on the hybrid layer capacitor, responsible for providing power for radio and other pulses over the full temperature range from –40 up to +85 °C. The task was to gather more power capability into a given form factor.

Figure 2 shows the development of the Tadiran HLC performance over the years undergoing a pulse of 350 mA at –40 °C.

The performance of the 1st HLC in 2000, generating a voltage of appr. 1.3V after 1.000 msec, has improved generation on generation. While the B-type model (developed in 2008) was designed to deliver appr. 2.7V under defined conditions, the P6-type is the fi rst system that clearly exceeds the 3.0V barrier.

Tadiran has been successful in getting ahead of that level with the new P6 HLC. Due to its particularly small size, it generates cost savings which makes it a perfect match for future applications: small size, high and reliable power capabilities, and competitive pricing.

At the same time the other advantages of the HLC technology stay valid:

• just one power providing component up to 3.9V level

• no balancing needed

• extra low self-discharge over entire lifetime

• no negative aging effects

• high equivalent capacity to cover long pulses. SEI
