The NiMH hybrid battery pack, which is removed from hybrid vehicles, has less capacity than the new battery modules. This hybrid battery is a good module if you can get one for around 1 USD. The capacitance of one module is 7.2V 6.5A. One module has six 1.2V cells. So, let’s check how we can reuse Hybrid Vehicle battery in our DIY projects.
You can add 2 modules each (Serial) and charge up to a maximum of 16.8v. It can be easily charged from the XH-M604 Charger Module using solar panels up to 170W (21A solar cell 36 panels). This is suitable for those who use 12v.
You can add up to three modules (Serial) and charge up to a maximum of 25.2v. This can also be charged from the XH-M604 Charger Module using solar panels from 200W upwards. (Solar cell 60/72 panels) This is suitable for those who use 24v.
Why most PWM chargers does not support charging Hybrid Vehicle Batteries
These battery modules cannot be charged with a standard PWM solar charging controller. Doing so will not result in real results and the modules will be wasted. A maximum of 8.2V should be given to one module, but it cannot be controlled by a PWM charger, it is even the same when you connect two modules. As the voltage of 16.8 is not supported by the PWM charge controller. Low charging can damage the modules in the long run.
If you have several NiMH hybrid battery modules, the first thing that you need to do is charge all the modules to the same voltage of 8.4V. After charging, check the voltage in individual modules with a multimeter and note it down. Leave it for a few days, check voltage again and arrange the pack from the lowest module to the highest module. You can parallel modules in this manner.
This is more suitable for 12v LED lights. 16.8v should be reduced to 12.5v. Use a 300W 20A Adjustable Voltage DC-DC Step-Down Converter to get 12V from these battery modules.
The use of these hybrid batteries is low risk and minimal maintenance. Also, it can be a cheap alternative as the hybrid battery price is extremely low.
