Hi,
I'm wondering if is ok to use a DC/DC Boost Step-up regulator (like **broken link removed**, LTC3862-2 or LTC3873-5) as charger for a lithium ion battery pack (42V 2A charging specs). I want to build a simple charger with those specifications :
For safety I have to know if this development plan is right. The result will be publish as an opensource project.
Any help will be appreciated,
Olivier
I'm wondering if is ok to use a DC/DC Boost Step-up regulator (like **broken link removed**, LTC3862-2 or LTC3873-5) as charger for a lithium ion battery pack (42V 2A charging specs). I want to build a simple charger with those specifications :
- input DC source (input 18-24V/4A),
- output a precise 42V +/- 1% for charging ,
- output current limiting (empty battery is like 0 ohm wire, a shortcut!! ) - I don't know if DC/DC can control this
- output shutdown when Icharge=1/100C (of battery capacity). - by adding a Attiny + FET
- reverse polarity protection with a Schottky diode
For safety I have to know if this development plan is right. The result will be publish as an opensource project.
Any help will be appreciated,
