Corolla eFX got back on track with a new Powerfinn PAC-800 charger feeding its traction battery pack!
I
had noticed that two Finnish companies Powernet and Powerfinn would
have suitable chargers to replace my faulty brandless chinese made
charger. I made a query for both of them and was quickly replied from
Powernet that they cannot sell to private persons. I cannot understand
this kind of business approach although it is a very typical one within
companies aiming for industrial markets. I was happy and also relieved
when Powerfinn was ready to see if we could find a solution for my
case:)
Powerfinn
did not have a suitable charging curve ready to fit my top balanced 24
series connected LiFePO4 cell's so I made an order for a Powerfinn
PAC-800 charger and software work to get a charging curve that I
wanted:constant current until 87,6V end voltage with a 2A charge cut off
current. The charger it self was nicely priced, but the software work
doubled the price. If software work is not needed the PAC-800 is very
competetively priced in my opinion. If there would be a simple user
configurable version of the PAC-800, it would be a superb product for
all EV builders;)
The
charger itself is a very nicely built device. It has an active PFC
which keeps the input current so low that I am able to use an indoor
heater to heat up my car on winter while charging from a 16A schuko
socket.
