Himfr.com Reports Atmel Introduced The Most Secure Battery-management Solutions

Recently, Atmel Corporation (Atmel Corporation) announced the launch of a new lithium-ion

(li-ion) battery management chip set for high-cell Number of automotive and industrial applications, such as electric / hybrid vehicles, electric bicycles or non-stop power supplies. Atmel is the only able to provide the highest security level with all the necessary features a complete two-chip protection solutions provider.

ATA6870/71 chipset with a hot-swap feature 6 cut-off frequency (cut-off frequency) lower than 30 Hz, integrated ADC and a stack of micro-controller power, without external filters, so than competing solutions require fewer external components. These features with Atmel's cost-effective 30-V CMOS technology, compared with existing solutions to save up to 60% of the cost.

ATA6870 is the industry's first cell contains a control high number of lithium-ion battery all the features needed for battery management IC, integrated 6 for voltage monitoring, battery balance and battery temperature measurement precision 12-bit ADC, as well as hot-swappable and stackable for the micro-controller integrated power supply and other unique features.

Atmel's product marketing manager for automotive high-voltage Claus Mochel said: "The safety and efficiency of batteries and automotive batteries for industrial applications is critical. Atmel's ATA6870 and ATA6871 new security concept with unparalleled and advanced parallel battery voltage measurement and equalization techniques are ideal to address these issues battery management solutions. "

Lithium-ion batteries from overcharging and deep discharge is very sensitive in these cases are likely to fire or explosion. In order to prevent this from happening, Atmel used its secondary protection device ATA6871, provides a special security policy, monitor the battery cell voltage and temperature to prevent thermal runaway of lithium-ion batteries or explosion occurred.

Once the battery cell in which an abnormal occurrence of the above, it will be through the Emergency Relay device off. ATA6871 with no external micro-controller or software will be able to run the built-in self-test program, with monitoring by the hardware thresholds, can provide the highest level of security monitoring capabilities of lithium-ion batteries. Even if the primary device is damaged, you can also ensure that the work properly.
