AI Customer ServiceJump-starting the BMS is a process that can be used to revive a lithium-ion battery pack that has a 0V output. According to the information above, this process can be done in cases where the BMS has tripped and is preventing the battery from functioning normally. To jump-start the BMS, you need to short the B- and P- connections on the BMS.
Under the hood on the right side you'll see two fuse/relay boxes. Pull lid on the one closest to the front of the vehicle. You'll see a red colored latch which you pull up on. It then swivels out of the way exposing a metal stud which is where the positive lead of the battery pack is attached.
Discard the pack if the voltage does not rise to a normal level within a minute while on boost. Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short.
First, locate the B- and P- connections on the BMS. They are usually marked on the circuit board or can be found in the wiring diagram for the battery pack. Once you have located the connections, carefully touch the metal wire or other conductive material to both connections at the same time.
Generally speaking, however, most BMS will completely disable the battery (go into protection mode) if the cells fall below around 2.4 volts or so. Once this happens, both charging and discharging is disabled. The only way to solve this is to access the individual cell groups and charge them to within range of the BMS.
The Cadex analyzer restored 91 percent to a capacity of 80 percent and higher; 30 percent were inactive and needed a boost, and 9 percent were non-serviceable. All restored packs were returned to service and performed flawlessly. This study shows the large number of mobile phone batteries that fail due to over-discharging and can be salvaged.
