Development of nickel-hydrogen batteries used toys
Tomy and Sanyo Electric announced on the 21st month on their joint development of a nickel-hydrogen pb994a battery, pb991a battery used toys "Eburi battery." The battery used in the unusually large current flow out of date will automatically limit the current flow, to prevent the temperature rise of the "PTC components", improve the battery safety in order to facilitate children's use. The battery will be Tomy's sales network in early November at the listing. 2 5, consisting of battery and charger package is priced at ¥ 3980, light 2 on the 5th battery price ¥ 1100. .
Ordinary Ni-MH rechargeable batteries have been mid-stream current is greater than ordinary batteries, at the electrode short-circuit the battery temperature to rise above 150 degrees Celsius. Toy manufacturers in general at the Toy factory's attention matters marked with "Do not use rechargeable satellite pro 2100 battery." 2 companies and the joint development of batteries because of cathode electrode Department at PTC containing components, the battery can heat the temperature controlled at 60 degrees Celsius.
Jin Shanghai to launch high-life battery for electric bike
Tianjin professional manufacturer of electric bike electric vehicles Da Chisholm Ltd. and Shanghai Industrial & Trade Co., Ltd., Shenzhen Electronics Technology Co., Ltd. three strong cooperation in the near future at Tianjin, Shanghai has also introduced the use of electric vehicles with the latest battery technology, "Da Rhone many "electric bike, battery life can be security for two years.
New satellite pro a100 battery , satellite pro a60 battery capture "water," "vulcanized" the two major technical difficulties, Life expectancy
Extended than that of ordinary products has doubled, greatly reduced the use of consumer costs, there is conducive to the promotion of electric vehicles.
Linear low-pin-lithium battery charger
LTC4006 has a quasi-constant frequency and constant off-time architecture, the architecture in the use of ceramic capacitors, even if circumstances do not produce audible noise. This IC has three models, respectively, with 8.4V (2 cell), 12.6V (3 cell) and 16.8V (4 cell) floating voltage, and its accuracy are ± 0.8%. Available charge current programming resistor to ± 4% typical accuracy. Electricity consumption for the instructions, a special feature of this charging current is expressed as micro-controller or A / D converter voltage. Resistor can be set using the total charge time for 1-3 hours. LTC4006 automatically recharge and trickle charge function.
LTC4006 job at - 40 ° C to 85 ° C temperature range to 1000 as a unit bulk purchase, each priced at 3.60 U.S. dollars.
LTC4006 performance summary:
2,3 or 4 for lithium-ion battery, charger controller complete
Up to 96% efficiency
Up to 4A of charging current
Automatically re-activate the built-charge termination functions
AC adapter current limit the maximum speed satellite a65 series battery , satellite 2100 battery charger
16-pin narrow SSOP package
