Hello,
My team is currently doing a project on electric vehicle. All the connections for the AC motor and lead acid batteries are done. Now, the next steps is monitoring the SOC and SOH of the lead acid battery pack.
The details of the battery pack is as below:
Battery types: Trojan deep cycle lead acid battery
Maximum current drawn from battery pack: 500 amps
Maximum and average voltage: 144 volts
So, may I know whether:
a) Is the BQ34Z110EVM suitable for monitoring such a high voltage and current battery pack?
b) From the datasheet, it shown that maximum charge and discharge current is 7A. If i scale down the 500 amps to 5 amps, will it affect the final output for SOC?
c) I'm planning to communicate the BQ34Z110EVM with Raspberry Pi, so that I can show out the SOC value on the LCD screen. May I know whether it is applicable to read the SOC data from the I2C port without using EV2300. Can I read the data by using the StateOfCharge() function, as shown in BQ34Z110 data sheet?
d) So if it is necessary to use the EV2300, is there any possible way to obtain the SOC and other data in register? The reason is i'm only planning to show the SOC,voltage and current data on my LCD screen while the electric car is running.
Thank you very much.
