Good find Bob!
I really like the presentation by an actual firefighter as he did a wonderful job explaining BESS pertinent to the firefighting trade (Tom Moloughney style).
I also admire the fact he did not condemn them, and admitted they play a critical role in the EV charging infrastructure.
Better disconnecting means accessible at a safe distance and within site (just like electrical motor/solar disconnecting rules), isolation of the equipment particularly from any fuel supply equipment/venting etc and additionally signage indicating the presence of Lithium Ion battery's within the equipment would be a great start
I really like this model

New charging stations open ‘northern gateway’ for electric vehicle travel
A Manitoba driver is celebrating what he described as a first-of-its-kind journey from just north of Winnipeg to Thompson in a fully electric vehicle — a trip made possible by new charging stations his company helped install across the province. He hopes the growing network will soon make most...
Free at Mercedes Benz High-Power Charging (HPC) network, running from April 11 to April 12, 2026. During the two-day event, all electric vehicles will be able to charge at no cost at participating locations across the province of BC.

The actual cause revealed:
A remote technician put the unit in diagnostic mode (which bypassed a bunch of safety features) and accidentally turned on the battery heater. After baking for 26 hours the battery caught fire.
Here is the incident summary from Technical Safety B.C.
"A remote technician from California accessed the charger online in New Westminster and placed it in a diagnostic mode. This mode allowed the manual functioning of lowvoltage components like HVAC and heaters, bypassing normal automated temperature controls. The technician inadvertently activated the battery heater. In diagnostic mode, the integrated safeties were bypassed meaning the heater would not shut off even if the battery got dangerously hot. Over the next 26-hours, the charger was left in diagnostic mode with the battery heater on. The charger’s BMS detected rising temperatures and issued a critical alert when the battery pack reached 55°C. The charger could not automatically turn off the heater because of the safety bypass in diagnostic mode. At this point, the system relied on alerts to prompt human intervention. The alerts were silent email alerts sent to Speed Charge representatives that did not require immediate acknowledgement and did not escalate. The alerts went unnoticed and were not acted on."
